Replacing rear shock absorbers on a VAZ 2115: DIY video instructions

On a VAZ-2115 car, the rear struts are replaced in case of mechanical damage to the unit or when the service life has been significantly exceeded. The shock absorbers must be replaced in pairs. If you install one new one and leave the second one alone, this will affect the ride. Even if one spring is working, it needs to be replaced - this is a prerequisite. The springs are changed in the same way.

troubleshooting

To identify damage to shock absorber struts and their elements, you need to perform the following steps:

1. Pay attention to the smoothness of the ride when driving, especially on uneven roads.
2. Take a closer look to see if the body is skewed on the rear side.
3. Look at the coils of the springs to see if there are any traces of impact on them. If so, the springs will need to be replaced. After all, if they break, the shock absorber will also not be able to work normally.
4. Press down on the left and right sides of the body, then release sharply. The body should swing a maximum of three times. If more, then the rack has become unusable and needs to be replaced.
5. If there are no signs of damage, carefully inspect the condition of the anthers. There should be no cracks or cuts on them. Otherwise, you will still have to remove the struts and replace the anthers.

Try to promptly replace all suspension components that have become unusable. After all, the slightest malfunction will lead to the car starting to pull to the side, and discomfort will be felt when driving over bumps.

How to determine if a shock absorber is faulty

The first thing to do is conduct a visual inspection. Oil stains on the shock absorber itself, boot or rebound buffer warn that it needs to be replaced. Also, uneven tire wear may be an indication of problems with the rear suspension strut.

When driving at a speed of more than 80 kilometers, the car's handling noticeably deteriorates, the steering reacts late to road irregularities, and the car's swaying does not subside.

But the most reliable way is to inspect it at a specialized service station stand.

What tools are needed for repair?

When working, you will need the following set of tools and materials:

1. Spring tightening device.
2. Pliers.
3. Heads for “13”, “17”, “19”, as well as ring wrenches with the same dimensions.
4. Hammer.
5. Ratchet driver.
6. A device for unscrewing the nut from the shock absorber rod.

Penetrating lubricant WD-40 is a must; you can’t do without it, since the spring mounts are located in places where there is constantly high humidity. In addition, dirt and dust penetrate there, so the threads become dirty and the nuts are difficult to unscrew. Therefore, clean all elements in advance and treat them with penetrating lubricant.

Signs of breakdown

Therefore, the car owner’s task is to monitor the condition of the suspension and front struts in particular, identify signs of breakdown in time and replace the units.

If your racks are really reaching the end of their service life, you can determine this by the following signs:

• The car behaves unstably on the road;
• When driving over obstacles, the car sways strongly;
• When entering turns and braking, the car is unstable;
• The braking distance increases noticeably;
• There are traces of oil on the body;
• There is a noise or knocking noise from the front of the car.

Some, even with such obvious signs of malfunction, continue to ignore the car’s need to replace the front struts. If you do not take any action, the consequences may be as follows:

• The car will bounce on every bump;
• Controllability in corners will decrease significantly, the car will pull to the side and turn around;
• Tires will lose their quality and wear out in the shortest possible time;
• Soon you will have to go to the wheel alignment.

If the replacement of the front struts on the VAZ 2114 is carried out in a timely manner, these problems and huge financial costs can be avoided.

Before you get started, we recommend watching a video on how to make the replacement. This is a useful lesson that will provide the necessary knowledge and concepts about the location of certain components of the unit.

If you decide to do everything yourself, then follow the specified algorithm. This will allow the replacement to be completed efficiently and without unnecessary manipulation.

1. Place the car on a flat area, preferably with a hole. Loosen the bolts on the front wheels. Be sure to turn on the handbrake and secure the wheels with chocks. You need to think about safety first.
2. Use a jack to lift the front of the car, then remove the wheel. Please note, when changing the front suspension elements, it is better to do this on two wheels at once, even if one of the struts is in satisfactory condition.
3. Lift the hood and look for the bolts that secure the struts to the body. Look for them on the left and right, near the windshield.
4. There is a plastic cap on the glass that needs to be removed. To do this, use a simple flathead screwdriver. The plastic element is pryed off and thus easily removed.
5. Unscrew the mounting nuts holding the rack on top of the body.
6. A brake hose with a bracket is attached to the rack. This element is also removable.
7. Using a wire brush, be sure to clean all the fastening elements of the struts to the body and chassis of the car.
8. Now take the pliers in your hands and use them to unscrew the nut. The one that holds the tie rod end joint to the A-pillar.
9. A puller removes the hinge from the shock-absorbing strut arm. If this is your first time changing them and no one has removed them before, be sure to tighten the nut a few turns, which will protect the threads.
10. Near the place where the fist is attached to the stand, there are nuts that should be removed. Just first mark where the adjusting bolts are located. This way you won’t have to go to a wheel alignment after replacing suspension elements.
11. Using a hammer, knock out the bolts that hold the element and the fist. The nodes release, allowing you to pull your fist down and reach the worn post.
12. Place the new part, then proceed to reassemble the unit in the reverse order. During the procedure, do not forget to check other components for defects, malfunctions, oil leaks, and so on.

When the procedure is completed, put on the wheels, but do not tighten the bolts tightly. By lowering the car from the jack, you can fully fix the bolts

This is an important rule that, unfortunately, many people forget.

Preparing for repairs

When replacing the rear struts of a VAZ-2115 with your own hands, you need to follow a certain sequence. Only in this case the repair will take place as quickly as possible. Rear struts are much easier to change than front struts - there are no steering ends, and there is no need to adjust the wheel camber and toe angles.

Vehicle preparation:

1. Place the car on a viewing hole or overpass.
2. Install wheel chocks under the front wheels.
3. Loosen the bolts securing both rear wheels.
4. Lift one side, completely unscrew the bolts, and place a reliable support under the body. Then do the same on the second side.
5. As a result, the suspension should be completely unloaded. You cannot work on a loaded suspension - it is dangerous.

You cannot place supports under the beam - in this case the suspension will be loaded. If you only need to replace the silent block of the VAZ-2115 rear pillar, then you only need to unscrew the lower fastening. There is no need to completely remove the assembly.

Leading manufacturers

When choosing new nodes, you should think about what exactly you want to get and what it will be like for you in the future. We recommend installing collapsible struts, since their design can be disassembled into parts, thereby simplifying and reducing the cost of suspension repairs. This is one of the key advantages of collapsible units.

KYB (Kayaba)

Look at the front element assembly in the photo to first understand what exactly this component of your car looks like. Choosing a manufacturer is a fairly pressing issue, since each of the options presented today has its own advantages and disadvantages. We invite you to familiarize yourself with them in the table.

From this we can conclude that spare parts from Kayaba are the optimal solution that will last a long time, reliably, and will not be afraid of harsh Russian winters, during which many analogues among the A-pillars simply will not be able to function normally, causing problems for you.

Removing the rack

After preparation, make sure that all threaded connections are treated with lubricant, the car is installed securely and will not fall during repairs. The step-by-step repair looks like this:

1. Remove the shield located in the luggage compartment that protects the upper mount of the shock absorber strut.
2. Remove the pad and support washer. All these steps do not need to be done if you only need to replace the silent blocks on the VAZ-2115.
3. Unscrew the nut that secures the shock absorber to the rear beam.
4. When removing the strut there is no need to compress the spring.
5. Lower the shock absorber and remove the lower cushion and support washer.
6. Slightly press the shock absorber rod down.
7. Remove the spring and protective cover, cover, bump stop.
8. Remove the shock absorber completely.
9. If there is no gasket on the spring, it should be at the top of the cup.

When replacing the rear struts on a VAZ-2115, it is imperative to install new gaskets, anthers and bump stops. Otherwise, the shock absorbers will not be able to work properly.

Abstract on replacing shock absorbers VAZ-2115

Here is a video tutorial on how to replace the rear shock absorbers on a VAZ-2115 with your own hands.

Shock absorber: its role in suspension

Car shock absorber. This is a mechanism in the car suspension that serves to partially compensate for vibrations (damping) that occur during movement, or to completely absorb them.

By providing the car with an even ride, the springs serve as protection for the car's chassis from overloads when driving on uneven roads and rough terrain. In a suspension, the shock absorber acts as an element to increase its elasticity together with the spring and torsion beam.

They are divided according to the types of springs:

• single-pipe gas;
• two-pipe gas;
• two-pipe oil.

The VAZ-2115 model has standard oil springs installed at the factory. In the future operation of the car, owners often make their own changes to the gasoline, depending on their driving style.

There are 3 types of shelves with different capabilities. You have to select them depending on which roads are moving. Oil (hydraulic). quite elastic. Designed for drivers who prefer a moderate, stable ride or frequent trips on unpolluted roads.

The role of shock absorbers in ensuring the safe operation of a car is often not considered by many, especially novice car owners. And this can lead to unpleasant and even catastrophic events. In the event of a malfunction or even partial loss of function of the shock absorber, the car wheel loses contact with the road.

As a result, the braking distance increases in the event of critical braking. When cornering, the car's stability deteriorates, the chassis and tires are subjected to higher loads, which leads to their wear, and so on.

How to determine a shock absorber

First do a visual inspection. Oil stains on the shock absorber itself, the log file, or the recoil buffer are warning signs that replacement is needed. Additionally, uneven tire wear may indicate obstructions in the rear suspension.

When driving at speeds of more than 80 km, the car's maneuverability increases noticeably, the steering responds late to road irregularities, and the car's swing does not subside.

But the surest way. This is a check at a special service station with a shield.

Replacement tool rear shock absorbers VAZ-2115

Once a faulty shock absorber is detected, it must be replaced. You can replace 100 or without the help of others. To do this you must have the following tools:

• wrench for loosening the damper nut;
• ordinary jack;
• pins, vices and pullers;
• hammer, chisel and pliers;
• keys and combination keys 13, 17, 19, 22, 24;
• ball key.

Procedure for replacing shock absorbers

Before removing the rear shock absorber of the VAZ-2115, you must use a glass rear support . Remove the plastic plug and unscrew the nut that secures the rod. For this, a special key is used, which simultaneously fixes the rod and unscrews the nut.

Finally, after pulling the nuts and washers with the rubber cushion, we raise the car with a jack and remove the rear wheel to gain access to the lower part of the mount

We fix the nut with an open wrench 19 and unscrew the bolt with a wrench 19, lubricate it with pre-penetrating oil, unscrew and remove the bolt from the hole, the rear shock absorber from landing. It's best to use a flat-head screwdriver, carefully supporting the bottom. The strut housing is on the side, lowered, and the shock absorber is removed.

The rubber gasket remaining inside the glass is removed with the same screwdriver. We disassemble the old shock absorber, removing the spring, rubber sleeve, cup, housing, chopper, and then in reverse (reverse) order we mount these parts onto the last strut.

Having replaced the spring, the last turn should take a position in the lower cup of the rear shock absorber, in which the end of the spring should not extend beyond the cup. And at the end of installing the rack, it should be oriented towards the wheels. Before installing the shock absorber, it is recommended to immediately put on the upper eraser and, to ensure that it does not change its location, use electrical tape to attach it to the spring coil.

At the end of the kit, the rear trim is installed in the reverse order, the upper nut and lower bolt securing it are tightened.

Do I need to change the spring?

A spring is a very durable element, but with prolonged use it can become unusable. Cracks appear, elasticity and length decrease. Diagnosing the condition is very simple:

1. Visually inspect the springs for cracks and deformations. If they occur, then the springs must be replaced.
2. Apply a load of 325 kg*s (or 3188 N). On export models of the car, the length will be 182 mm. For those produced for the domestic market, the length should be more than 201 mm. If less, then the spring must be replaced.

The springs that were installed on the VAZ-2115 are marked in the form of the letters A and B. The former are capable of working with higher loads. Be sure to install new springs with the same class.

When to change shock absorbers and struts

The first reason for replacement is leakage. Its appearance is accompanied by various types of knocking noises in the front and/or rear suspension. It's quite easy to check this yourself. Firstly, you need to carefully monitor the operation of the shock absorption system. Secondly, you need to approach the front wheel of the car from the side, put your hands on the hood or fender, and then rock it 2-3 times. When the shock absorber compresses to its lowest point, you must suddenly remove your hands. Most likely, everything is fine with the stand if the car rocks easily once and then stops.

The shock absorber/strut must be replaced if cracks appear on the surface of the part. In addition, it is better to purchase new parts if it is clear that the car has different stiffness on the right and left sides. The suspension should work equally well on all sides and not knock. Defects also appear in the form of shaking when driving.

Assembly of the unit

After purchasing all the new components, you only have to do a few simple steps:

1. Compress the spring using a puller. It must be installed in such a way as to engage at least three turns.
2. Install rubber pads on the spring; they can be secured with tape or tape.
3. Place the bump stop on the rod and the boot on top.
4. Install the rod into the hole in the body and tighten the nut.
5. Secure the lower part of the shock absorber to the rear beam by aligning the holes and inserting the bolt. Tighten the nut.

Check the tightness of all threaded connections. After a run of 50-100 km, it is recommended to re-tighten all the nuts. When replacing the rear struts of a VAZ-2115, use nuts with plastic bushings - they are much more reliable.

Let's summarize

As you can see, the procedure is not complicated, you just need to know what and how to do. For a beginner, the event will take up to 4 hours, but if you have the skills, you can complete it in 1.4-2 hours. It is advisable to check the results of work performed for the first time using the wheel alignment method or go to a car service center and use a special stand. The price of the service is affordable, but you will be convinced of your competence as a repairman. There is no definite answer to how regularly rear struts require replacement - it all depends on the quality of spare parts, intensity and care of operation, and driving style.

Replacing the front struts of a VAZ 2114

And now more about how to replace the front strut supports of a VAZ 2114 with your own hands. First, you should prepare the car for work - disconnect the battery, install stops under the rear wheels so that the car cannot be moved. And we begin:

1. Raise the side to be repaired using a jack.
2. We remove the wheel. Need I say that you need to loosen the bolts in advance?
3. Place the brake pipe to the side so as not to damage it.
4. Using keys “17” and “19”, unscrew the bolts securing the strut to the hub. These bolts and nuts can be thrown away immediately - reuse is unacceptable. Firstly, there is a plastic lock on the thread, and it is designed for a small number of tightenings. Secondly, metal fatigue affects and the bolt can become deformed when tightened.
5. On a VAZ 2114, the front strut can be replaced without removing the spring. But you still have to unscrew the nut and remove the tie rod end.
6. Using a key set to “13” you need to unscrew all three nuts that secure the support bearing housing to the car body.

After this, the entire rack assembly can be removed and a new one installed in its place. As you can see, replacing the front struts of a VAZ 2114 is not that difficult. But if you install an old spring, you will have to tinker with disassembling the old unit - this can be problematic, since long-term use takes its toll on it. Rust appears, the metal “sticks”, sometimes even penetrating lubricant cannot help.

The repair procedure is the same on both sides. Installation of a new rack is carried out in the reverse order

It is important to observe the tightening torque of threaded connections, since your safety depends on it. Use a torque wrench for convenience.

At this point, the replacement of the front struts of the VAZ 2114 is completed, you can continue to use the car.
