Video of replacing the crosspiece VAZ 2105, 2106, 2107

Rules for choosing a cross

This is what the part looks like

On VAZ 2106, auto mechanics advise changing the crosspieces as a set. In some cases, 3 crosses are replaced at the shank. The best parts are made in Germany. Products from the following manufacturers are installed on the VAZ 2106.

1. Trialli with oiler. Made of steel and uniformly hardened over the entire surface. Such parts can withstand significant dynamic and statistical loads.
2. Kraft. Made from anti-corrosion stainless steel alloy. The manufacturer provides a warranty on the part.
3. Weber, GKN and other foreign manufacturers. The disadvantage of such products is the need to adjust the retaining rings.
4. Domestic products. Plus - affordable price.

Replacing the crosspiece on a VAZ 2106 car involves dismantling the cardan. To do this you will need an inspection hole or a jack. Removal and installation are carried out using keys “12”, “13”, “27” and a hammer.

The suspension bearing is installed using a tension puller and an old flange. The release spring is disconnected from the bracket using pliers, then it is dismantled. The cardan is jammed with a screwdriver. Unscrew the nuts and remove 1 end of the cardan. The plank and plate of the suspended structure are dismantled. The cardan is removed. The location of each part is noted so that the balancing of the shafts is not disturbed. The retaining rings are dismantled. Using a puller or vice, remove the bearing. If an anvil is used for this, then the cover of the 2nd bearing should not rest against the plane of this device.

The VAZ 2106 cardan is turned over 180°. Similar actions are carried out with the 2nd bearing. If the process is carried out without a puller, then the blows are made on the crosspiece or on the 2nd part of the cardan (with a transverse crosspiece). The bearing is pulled out of the fork. The transverse cross is disengaged. The puller is installed on the 2nd pair of bearings.

Which crosspieces to put on the “six”

If you listen to the opinion of service station specialists, they recommend replacing both universal joint crosspieces, even if only one of them fails. But not everything is so simple. The crosspiece located at the front of the driveline travels much longer than the rear one. There are situations when a part in the shank is changed three times, but near the outboard bearing there is no need to replace it. When choosing crosspieces for your car, you should not chase a low price, since repairs will ultimately cost more. Let's look at some hinge manufacturers that you can trust with your choice:

1. Trialli. Made of high carbon steel and evenly hardened over the entire surface. The product is able to withstand high impacts of dynamic and static nature. The seal has an improved design, which increases reliability and protection against dust and sand getting inside the bearings. The Trialli crosspiece is made of high carbon steel, which increases the reliability of the mechanism
2. Kraft. The part is made of a special stainless alloy that is resistant to corrosion. The manufacturer provides a guarantee of high quality, which is embedded in multi-stage control during manufacturing. Kraft universal joints are made of a special stainless alloy that is resistant to corrosion
3. Weber, GKN, etc. The crosspieces of these and other imported manufacturers are of good quality, but sometimes the stoppers have to be adjusted to the location.
4. The most affordable option for a universal joint is a domestically produced part. There is no need to talk about the quality of such a product, so it depends. The advantage of domestic crosspieces is their affordable cost, but the quality of such products leaves much to be desired

Before purchasing and installing a universal joint, be sure to consider the size and shape of the cups

Attention should also be paid to the hinge pins. They should not have any burrs, marks or other defects.

For domestic cars, it is better to give preference to crosspieces with a grease fitting, i.e., serviceable ones, which will allow you to periodically renew the lubricant in the bearings. The seals must not have any defects, such as visible tears or manufacturing defects.

When choosing a cross, attention should be paid to the size and shape of the cups

Table: parameters of the universal joint for the “classic”

Step-by-step installation of the part

Before installation, the crosspieces are checked and lubricant is applied to the parts. For lubrication, use “Fiol” or another substance of similar effect. The bearing housing is inserted into place, the forks are pressed into place. Then the retaining rings are installed. They hit the forks with a hammer. All gaps existing between the bottom of the bearing and the ring disappear. To check the free movement of the main part, use a feeler gauge. The stroke should not exceed 0.04 mm. Otherwise, a larger diameter ring is installed.

The rings come in 5 sizes, each with its own color. If the thickness of the part is 1.5 mm, then the product is not painted.

Disassembling the cardan to remove the cross

Replacing the crosspiece involves installing a new outboard bearing. This procedure is carried out after dismantling the cardan and crosspiece. Then unscrew the front shaft nut. The puller is fixed to the fork. Using a hammer, the fork is moved and pressed from the splines. The outboard bearing fixing bolts can be unscrewed with a 13 key.

The main part is knocked out of the shaft. Reassembling the cardan is carried out in the reverse order. If the above process is carried out without dismantling the cardan, then an assistant will be required.

Signs of a faulty VAZ 2107 suspension bearing and how to check the driveshaft yourself

The first signs of malfunction and wear of the VAZ 2107 (PP) suspension bearing are vibration and knocking of the cardan when the car begins to move. After accelerating the car, the knocking gradually disappears, turning into vibration and noise. If there were no problems with balancing the axle before, but knocking suddenly appeared, then it is necessary to immediately diagnose the PP.

Diagnosis is performed in the following order:

1. Place the car on an overpass, lift or pit;
2. Locate the driveshaft under the car;

1. Check the play of the PP by moving the part by hand in the axial direction - free movement is not allowed;
2. Rotate the cardan and listen to how the bearing works - vibration, rolling, grinding, knocking are not allowed;
3. Inspect the product body, including the tightness of the bearing seals - lubricant leakage is not allowed;
4. Make sure that the outboard bearing and bracket are not loose;
5. The presented videos show how the VAZ 2101-2107 suspension bearing (injector) hums, as well as how to determine if the intermediate support is faulty.

How to change the crosspiece 2106 with your own hands

In the article you will learn for what purposes the 2106 crosspiece on the cardan shaft is needed, as well as how to replace it with your own hands. The Six is ​​one of the few cars that can be repaired independently, without the help of specialists at service stations. Unfortunately, everyone tries to earn as much as possible, and mechanics are no exception. Along with replacing the crosspiece, they will force you to install a new driveshaft, and this significantly increases the cost of service. Moreover, you can also run into “black” craftsmen who will include in the cost of repairs those items that were not actually completed. But we have moved away from the topic of conversation, let's still look at how a car is repaired.

Replacing cardan crosspieces on VAZ 2101-VAZ 2107

Welcome! Cardan crosspieces - in total, the Zhiguli driveshaft uses two crosspieces, one is installed in the central part, and the other in the place where the driveshaft is connected to the gearbox; replacement is easy if the car is new or if the cardan transmission has recently been rebuilt, but in the case when the cardan haven’t touched them for 5 years, the crosspieces will be much more difficult to change, since they rust and begin to be removed very reluctantly, if this is the case for you, then stock up on special ones. in addition, a puller for crosspieces (Actually, it is needed in any case, but the work can be done without it), a soft metal hammer and kerosene (Or any other similar liquid).

Note! You can change the cardan crosspieces using the following set of tools: Wrenches “13” and two of the same but size “19”, you will also need socket heads, approximately sizes “11” and “27” and of course a wrench, because the sockets heads without it are nothing, just beautiful elements, all this will come in handy with an ordinary hammer and a hammer made of soft metal (In the event that the cardan transmission has not been touched for a long time), there will also be special pliers needed to remove the retaining rings and, by the way, about the retaining rings themselves don’t forget the rings for the crosspieces, they will definitely need to be replaced with new ones, you will also need mandrels with which the bearings on the crosspieces can be pressed out, a universal puller and Cobra-type pliers!

Summary:

Where are the crosspieces located on the driveshaft? We will not only show where they are located, but also provide a photo of what they look like. You most likely have already looked a little lower and noticed this photo, which shows the location of the crosses with red arrows, and the small photo shows one of the crosses, next to it There are four retaining rings, the same ones we talked about just above.

When do you need to change the crosspieces on the driveshaft? Signs that the crosspieces have become unusable are the following: Vibration in the body, clicks, extraneous knocks in the lower part when the gear is engaged and when the gas is suddenly released. After the signs appear, you need to crawl under the car and check the crosspieces for wear with your hand, how to do this is described in the video Very little detail below:

Replacing the crosspiece of a VAZ 2106 - nothing is easier

So what does the cross do? With its help, it becomes possible to bend the driveshaft. Pay attention to how the rear axle flange and the gearbox shaft are located relative to each other. That's right, the axis of the second one is located higher, therefore, you need to somehow cheat in order to transmit the rotation. The driveshaft must “break” in two places so that movement from the gearbox to the rear axle is transmitted without any problems. In addition, the center of gravity of the entire propeller shaft must be such that axial runout does not occur. Don’t forget about the VAZ 2106 suspension bearing; it is used to attach the shaft to the bottom of the car. If it is destroyed, the axial runout increases, which leads to failure of the crosspieces.

Auto repair school – DIY car repair

External view of the VAZ 2107 cardan cross
When the car is not loaded, its axle is located lower than the gearbox. If the car is heavily loaded or driving on an uneven road, the bridge constantly moves up and down. A driveshaft is attached to the bridge. Consequently, its angle of inclination is also constantly changing. The purpose of this shaft is to transmit torque from the engine to the wheels. A cross-shaped joint called a cross is attached to it. It allows you to effectively transfer torque from the engine to the wheels regardless of the position of the cardan.

Replacing the driveshaft crosspiece of a VAZ 2106

Replacing the driveshaft crosspiece of a VAZ 2106

So, let's start, as always, briefly and without unnecessary, unnecessary information! It is better to take the original VAZ crosspiece. My choice fell on a domestic plant, the cost is about 120 UAH ($5). It is also worth buying 4 locking rings. Old ones, as a rule, break and become deformed during dismantling.

Before starting work and removing the cardan, it is necessary to make marks (.) on all parts and joints of the cardan, otherwise, if it is not assembled correctly, it will knock, vibrate, and generally fail.

The cardan is connected with 4 x 13 bolts to the rear axle shank. We unscrew them

Next, unscrew the mounting of the outboard bearing.

Remove the cardan from the gearbox

Remove the retaining rings from the crosspiece. We didn’t have a special puller, we used ordinary pliers

While the cordan is removed, we get into the car, “accelerate” and take an outrageous photo!))

(don't forget to remove the handbrake)

Next we knock out the cross. If there is a tube of suitable diameter, then this is good. In this case, available materials were used: a socket wrench (for replacing wheels), an adjustable wrench (placed under the crosspiece), and a hammer.

Knock out the old one, insert the new one

We remove the landing cups from the opposite edges of the cross and insert it into the seat. Carefully put the cups back so as not to scatter the needles in them.

Cardan shaft. Crosses and stuff. All questions. | Topic Author: Worley

It's about selection, operation, replacement, etc. Go.

Alexey (Zayd) The vaunted GKN lasted for two years.

Alexey (Zayd) driveshaft of a VAZ 2107 car - disassembly and assembly | VAZ 2107 driveshaft repair https://car-exotic.com/vaz-cars/vaz-2107-car-transmiss..

Gennady (Dritan) Good day. A question arose here about the cardan. It creaks when driving, there is no way to localize where exactly (shank, crosspiece, etc.) the problem is. Will lubricating the fastening parts, for example with lithol or wd40, help? Or is there another reason? PS pillows and other fastenings are intact

Alexey (Zayd) Gennady, I think that if it creaks (rotational creaking), then anyway, replacing the crosspieces is a good place to start. In most cases, after long-term use, it’s just a nightmare - just rust. And here lubricant will not help - stupidly change it and that’s it. After removing the cardan, be sure to check the tightness of the shank nut. Well, that’s all along the way.

Gennady (Dritan) Alexey, thank you very much, I’ll take it into account. I'll check everything soon

Alexey (Zayd) GKN - myth debunked.

Alexey (Zayd) Installed https://avtopasker.ru/goods/466.htm https://avtopasker.ru/goods/1862.htm By the way, a strange thing - the crosspiece is the cheapest of those offered - https://avtopasker.ru/ catalog/index.php? search=? 4?? 4?? .. Well, we'll see.

Vladimir (Gauri) Alexey, It's time to change the crosspieces or the crosspiece shorter sound (ringing) when moving backwards. Which crosspiece to choose from? and should we change both of them or is it just the building that is damaged?

Alexey (Zayd) Vladimir, I usually change both at once. GKN lasted for 1.5 years. The rest are also roulette.

Maxim (Dash) Guys, this garbage appeared, when you start driving, the car starts to shake (vibrate terribly), what could be the problem?

Alexey (Zayd) Maxim, the problem may be in the clutch. The likely result is failure of the release bearing.

Maxim (Dash) Alexey, I just replaced it over the weekend

Alexey (Zayd) Maxim, Unfortunately I won’t tell you more. Work to figure out why. Much has been said about disadvantages similar to those described by you. At least more than you said. — the type (brand) of clutch, the temperature at which this occurs (usually when overheating in the heat), etc. are not mentioned.

Maxim (Dash) Valio clutch. Plastic release occurs after 5 minutes from start

Alexey (Zayd) Maxim, Valeo is a respected brand. Work softly, for a long time and reliably. If not a fake.

Maxim (Dash) Today I changed the crosspieces and the suspension bearing. A whistling appeared when driving. As the speed increased, the whistling intensified. What’s the problem?

Alexey (Zayd) Maxim, please name the manufacturer of the crosspieces. We won't buy these.

Maxim (Dash) Alexey, ANDYCAR

Alexey (Zayd) Maxim, Czech Republic. Or is it still native China? O_O https://avtopasker.ru/goods/29275.htm

Removing the cardan.

1. We carry out the work on an inspection pit or a lift. Remove the handbrake cable spring.

2. Apply marks to the joint between the cardan and the gearbox flange. Using a 13mm wrench, unscrew the four self-locking nuts. At the same time, we hold the cardan from turning with a large screwdriver.

3. Remove one end of the cardan.

4. We note the relative position of the cardan and the centering flange of the elastic coupling...

5. Next, bend the 4 locking tabs on the seal ring near the elastic coupling...

6. ...and move the holder along with the seal towards the cardan.

7. Using a 13mm socket, unscrew the two nuts and remove the safety bar.

8. Holding the cardan, use a 13mm wrench to unscrew the two nuts and remove the outboard bearing plate from the mounting studs to the body. It is secured to the body through rubber washers.

9. We take out the cardan from the splines of the elastic coupling flange and remove it.

• We first mark the relative positions of the parts (cardan joint forks) so as not to disturb the factory balancing of the cardan shaft during assembly.
• Then we mark the locking rings and their seats in order to install them in their standard places during assembly. Remove the retaining rings (four from each hinge).

• We press the bearings out of the hinge fork using mandrels of a suitable diameter.

• Since the bearings are not pressed in completely (the joint cross rests against its fork), we remove the bearing using pliers
• We disconnect the cardan joint by moving its crosspiece in the direction of the removed bearing, slightly turn the crosspiece and remove it from the hinge fork.

• Press the opposite needle bearing out of the hinge fork.
• We carry out steps 3 and 4 for other needle bearings and remove the cross.
• We do the same with the second cross if necessary.

As you can see, replacing the crosspiece on a VAZ 2106 with your own hands is not particularly difficult.

If necessary, replace the intermediate bearing

• Unlock the nut securing the front shaft fork. We unscrew it and press the fork using a puller from the front shaft.

• Remove the dust deflector from the front shaft.
• Screw the nut onto the threads of the front shaft so that it is flush with the shaft itself
• We compress the intermediate shaft support (we apply force to the inner race of the bearing) and unscrew the nut.
• Remove the support along with the bracket from the propeller shaft

• We unscrew the bolts securing the bracket to the support, remove all the washers and disconnect the bracket from the intermediate shaft support.

Defective parts

• We thoroughly clean the parts with a brush before inspecting them.
• To cull the cardan transmission elements you will need: a bore gauge, a dial indicator.
• Since we have removed the cardan and disassembled it (albeit partially), we check the integrity of the welds. Drive shaft splines so that they do not contain wear marks
• For the rear cardan shaft, we check the presence of balancing weights, the condition of the seams and measure the diameters of the fork holes for the needle bearing. Dents of pipes and misalignment of the holes of the cardan forks are not allowed.

• We check the condition of needle bearings, oil seals, their cages and spider spikes for damage and significant wear.

• At the same time, check (while the cardan is removed) the condition of the rubber coupling of the cardan.
• The presence of cracks, mechanical damage or detachment of rubber from steel liners is not acceptable.
• We check the intermediate support for deformations. Cracks or ruptures of the elastic clip, as well as peeling of the rubber, are not acceptable. Replacing the defective support assembly
• We check the intermediate support bearing, rotate its inner race in two directions, while pressing it against the outer race (the inner race should rotate smoothly). We check the bearing seals for mechanical damage.
• We replace all defective parts.

We assemble the cardan in the reverse order, taking into account the features given below:

• Before installing the front shaft fork, lubricate the splines of the fork and shaft with grease.
• When installing the front shaft fork, tighten the nut securing it with a torque wrench 8.1-10 kgf•m (79.4-98 N•m) and tighten the nut with a chisel.
• When installing the oil seal race, the oil seal itself with the flange onto the front driveshaft splines, we fix the oil seal race by bending its three “tendrils”.
• Using an oil syringe, coat the splined part of the front driveshaft. Remove excess grease with a rag. We unscrew the grease nipple and screw in the plug in its place.

• Lubricate the needle bearings and stud surfaces of the universal joint with grease.

• Having installed the bearing races, we determine the gaps between the end part of the bearings and the upper edge of the annular groove located on the hinge fork using a flat feeler gauge. The permissible gap is within 1.5-1.66 millimeters.
• We select the thickness of the locking rings based on the obtained gap values ​​(we measure the rings with a micrometer).
• After installing the rings, we apply a couple of blows with a rubber hammer to the hinge forks from the reverse sides (this ensures the contact of the needle bearing races with the locking rings and the free movement of the cross).

Lada 2106 “Red Garnet” › Logbook › Replacing crosspieces

Good day to all!

Yesterday we replaced the universal joint crosspieces. Due to noise during gear shifting. As it turned out, the bearings on the crosspiece were worn out.

How to determine crosspiece wear

If, when lowering the pedal, when shifting gears, or during sudden acceleration or braking, you hear a knocking sound in the cardan drive, vibration of the axle, this indicates severe wear of the crosspiece and bearings. It is urgent to carry out work to replace these worn-out parts. You can, of course, ignore the symptoms, but then there is a high probability that the bearing will collapse and the cardan will fall out someday right on the road. The gearbox may also be damaged.

You should have the following tools at hand: open-end wrenches 12 and 13, a copper or aluminum adapter, compression pliers, a hammer, a socket wrench 13 and 27. If it becomes necessary to replace the outboard bearing, you will need a tension puller and an old flange of the elastic coupling.

Removing the cardan on a VAZ 2106 Sequence of actions when removing the cardan

Using round nose pliers or pliers, disconnect the tension spring from the body bracket and remove it.

Mark with paint the joint between the gearbox flange and the cardan (this will be useful during assembly). Having jammed the cardan with a screwdriver so that it does not turn, unscrew the self-locking nuts (there are four of them) with a No. 13 wrench.

After the nuts are unscrewed, one end of the cardan can be easily removed.

The relative location of the elastic coupling flange and the cardan should also be carefully noted.

Bend back the 4 locking tabs on the seal ring near the elastic coupling.

Carefully move the cage towards the cardan (together with the seal).

Using a 13mm socket, unscrew the two nuts and remove the safety bar.

Using a 13mm wrench, unscrew the two nuts and remove the plate of the outboard bearing, secured to the body through rubber washers, from the studs that secure it to the body.

Remove the cardan shaft from the splines of the flexible coupling flange and remove it.

Which crosspiece is better to install?

Car service specialists say that if the time has come to change the crosspiece, then it is better to change them as a set, both of them. In fact, this is not always the case. The front crosspiece, as a rule, lasts much longer than the rear one. Sometimes three crosspieces are replaced at the shank, but at the outboard bearing the crosspiece remains fully functional.

Experts advise not to “kill the ears of the cardan”, and not to change the crosspiece unless necessary.

When purchasing, you should not save on cost, it will be more expensive. Quite good crosspieces made in Germany are of high quality and come complete with retaining rings, which come in very handy if the “original” ones break during disassembly.

Trialli reinforced crosspieces (with an oiler at the end of the tenon) - made of high-carbon steel, uniformly hardened over the entire surface. Withstands high static and dynamic loads. The improved seal design provides reliable protection from sand and dust to the bearing units.

The crosspieces (with oiler) are made of a special stainless steel alloy that is resistant to corrosion. The manufacturer guarantees high quality based on multi-stage control during the production process.

Crosspieces from Weber, GKN, etc. The only disadvantage of imported crosspieces is that the retaining rings often need to be adjusted.

Installation of crosspiece VAZ 2106

First, you should check the presence of lubricant in the new crosspiece on the inner surface of the bearing housings and the spikes of the crosspiece. If necessary, lubricate the crosspiece bearings with Fiol. Place seals and plastic plugs on the crosspiece. Insert the spider spikes into the fork. Place the bearing housings and press them into the fork holes. The bearing should go deeper than the groove for the retaining ring. Install retaining rings. Tap the forks with a hammer (preferably one with a plastic striker). The gap between the bottom of the bearing and the retaining ring is eliminated under the influence of impacts and gaps will appear between the ends of the crosspiece studs and the bearing housings. Use a feeler gauge to check the axial free play of the crosspiece - it should not exceed 0.04 mm. If the axial stroke is greater, replace the ring with a larger diameter. Retaining rings are available in five sizes. For clarity, each size has its own color. Rings with a thickness of 1.5 mm are unpainted, 1.52 mm are dark brown, 1.56 mm are blue, 1.59 mm are black, 1.62 mm are yellow. Check the balancing of the cardan drive and the ease of rotation of the hinge forks.

How to diagnose wear on crosspieces

Replacing the crosspiece in a VAZ 2106 is carried out after diagnostics:

• When, during rapid acceleration or braking of a car, when changing gears, a knocking sound from the cardan transmission or vibration of the axle is heard, all this indicates wear of the crosspiece and its bearings. There is an urgent need to replace the VAZ 2106 crosspiece, which has become unusable.
• If you don’t pay attention to these signs in time, then the result will be destruction of the bearing and the cardan falling out directly onto the road. The axle gearbox and the underbody of your car can also be damaged.

Buy a “VAZ” crosspiece, do not forget to purchase spare retaining rings (if they are not included in the kit), because old rings, as a rule, become deformed or break.

Tool required for replacement

Replacing the driveshaft crosspiece of a VAZ 2106 requires the following tools:

• Two open-end wrenches 13 and 12
• Socket wrenches 27 and 13
• Copper or aluminum extension
• Hammer
• Compression pliers with thin jaws to remove circlips
• Two mandrels for pressing out the cardan cross bearings.
• Universal puller
• Ticks
• Chisel
• Large screwdriver

We remove the cardan

Replacing the VAZ 2106 crosspiece with your own hands is not possible without removing the cardan from the car. So:

• We remove the cardan on a lift or inspection hole. Unhook the handbrake cable spring.
• Using a chisel, we apply marks at the junction of the cardan and the gearbox flange. Using a 13mm wrench, unscrew the nuts (there are four of them). Use a large screwdriver to secure the cardan shaft from rotating.
• Remove the rear end of the cardan.

• Use a chisel to mark the position of the cardan and flange of the rubber coupling

• Then we bend the locking tendrils of the seal ring near the rubber coupling
• We move the cage with the seal together towards the propeller shaft

• Using a 13mm socket, unscrew the nuts and take out the safety bar
• Supporting the cardan, unscrew the nuts using a 13mm wrench and remove the plate securing the outboard bearing from the studs. It is attached to the body using rubber washers.

• We pull the cardan out of the slots inside the rubber coupling flange and take it out

It is first recommended to watch how to replace the crosspiece of a VAZ 2106 video.

Signs of faulty crosspieces

The VAZ 2106 crosspiece, like any other car part, has a certain service life. Theoretically, the service life of the part is quite long, about 500 thousand km, but the real figures are 10 times less. Therefore, replacement has to be carried out after 50–70 thousand kilometers. This is due not only to the quality of the parts, but also to our roads and the intensity of vehicle operation. Lack of periodic maintenance of crosspieces only brings the need for their replacement closer. The following characteristic signs indicate that there is some problem with the hinge:

• blows and knocks;
• chassis vibrations;
• squeaks when driving or accelerating.

Clicks and bumps

Often problems with crosspieces appear when the seals are damaged and dust, sand, dirt and water get inside the bearings. All these factors negatively affect the service life of the product. When the joints wear out, clicks will be heard when changing gears while moving, impacts at a speed of about 90 km/h, and a crunching or rustling sound will also appear. If metallic sounds occur, it is recommended to twist parts of the cardan, for example, by placing the car on an overpass. If large play is detected, the crosspieces will need to be replaced.

When diagnosing the gap in the crosspieces, the gearbox must be in neutral gear.

Video: play of the cardan cross

If clicks appear in the cardan area on my car, but I am sure that the crosspieces are still in good condition and should move, then, most likely, there is simply not enough lubrication in the hinges, for which they need to be injected. If clicks appear, I advise you not to delay maintenance, since the bearings will break and it will no longer be possible to do without replacing the crosspiece.

Creaks

The cause of squeaks in the area of ​​the driveshaft is usually associated with souring of the crosspieces. The problem is clearly noticeable at the beginning of the movement and when driving at low speed, while the car creaks like an old cart.

The malfunction occurs when the hinges are not maintained, when the bearing simply cannot cope with its task. Sometimes, after removing the cardan, it is discovered that the crosspiece does not move in any direction at all.

Video: how the cardan cross creaks

Vibration

Malfunctions in the form of vibration with the universal joints can occur when moving forward or in reverse. The problem can be present with both old bearings and new ones. In the first case, the malfunction is caused by jamming of one of the hinges. If the vibration persists after replacing the crosspiece, then a low-quality part may have been installed or the installation was performed incorrectly. The crosspiece, whether old or new, should move in any of the four directions freely and without jamming. If you have to exert little effort when moving the hinge by hand, you can lightly tap the bearing cup; it may not be seated properly.

Vibrations in the driveshaft may be due to imbalance. The reason may lie in the impact on the cardan with something hard, for example, when hitting a stone. The balancing plate could also fall off the shaft. In such situations, you will have to visit a car service to eliminate the imbalance, and possibly replace the shaft itself.

Cardan vibrations are caused not only by the failure of the crosspiece. From personal experience I can say that the problem also manifests itself when the outboard bearing breaks, when the rubber in which it is held breaks off. The vibration is heard especially clearly when reversing and when starting to move in first gear. Therefore, before you start replacing the crosspiece, it would be useful to check the driveshaft support.

Replacement and repair of muffler for VAZ 2104–2107 cars

To replace the muffler you will need:

• inspection hole or lift;
• screwdriver;
• a set of car keys;
• hammer.

Removing and installing the muffler

To dismantle the “glushak”, repair it, and then return it to its place, follow this sequence of actions:

1. Drive the car into the inspection hole. Stop the engine and turn off the ignition. Wait until the exhaust manifold cools down.
2. Unbend the hooks of the rubber suspension straps of the muffler.

Using a screwdriver, straighten the hooks of the rubber straps on which the muffler is suspended

Unscrew the exhaust pipe fastening to the rubber cushion with a wrench

Loosen the clamp between the pipes of the main and additional muffler

Carefully knock the resonator out of the mount by hitting it with a hammer through a wooden spacer

Unscrew the exhaust pipe from the gearbox bracket

Carefully bend the stoppers and unscrew the exhaust pipe from the manifold

Install the new muffler in the opposite order of removal. However, do not use a used gasket. Before assembly, treat the pipes at the places where they are connected with clamps with graphite lubricant.

In 1979, at VAZ, a car was built especially for “dear Leonid Ilyich,” which received the common name “half past six.” This happened after the presentation of the VAZ-2105 and 2107 models to the country's leadership, the serial production of which was still quite far away, and Brezhnev wished to give such a car to one of his family members. The result was a unique car, the body and interior of which was a hybrid of a “six” and a “seven” - hence the name.
