The rear axle often operates at high temperatures (about 140 degrees). Under the influence of air, the composition of the lubricating fluid oxidizes, clots and sediment form, and viscosity decreases. As a result, the protective lubricant becomes useless. And the parts of the drive axle are destroyed. Changing the oil in the rear axle of a VAZ-2107 can significantly extend the life of the vehicle.
The design of the VAZ-2107 gearbox is a hypoid gear with offset axes. This structure reduces noise levels during grinding of mechanism parts. But at the same time, additional sliding can cause knots to jam. High-quality lubrication protects against the occurrence of this type of malfunction.
How much oil is in the gearbox of a VAZ 2101
Changing the oil in the gearbox rear axle on a VAZ 2101-VAZ 2107
The oil in the gearbox with all the mechanisms that rotate and rub against each other needs oil, just like the gearbox, there are gears inside it (they are iron ), which rub when they work together, and if they are not lubricated, they will quickly fail (they will appear on the cones or become completely deformed, and the gearbox will have to be replaced), and when lubricated they will already rotate and rub against each other with even less friction, and for that matter the wear parts will be reduced (they won't run as fast), not counting, I'll still have quieter gears in the gearbox, and so it won't buzz and vibrate as much as it would if you drained the oil completely and started the car.
Changing the oil requires a minimum of tools and a minimum of time, so it is useful to use tools: a wrench around "17" and a hex somewhere around "about 12", a useful cloth to clean the drain plug from all the dirt, wells and the oil itself, by the way, about 1.3 liters of transmission oil goes into the gearbox (the drain tank is about 2 liters. Take or even put a bowl, it’s just not convenient to pour oil into a small tank)!
Where is the rear axle gearbox located?
It is located in the center at the rear under the bottom of the car, there is a driveshaft (some people call it a helical shaft) and it is connected to this gearbox itself, in the photo below you can clearly see the gearbox as it circulates in the circle there are two more plugs that are needed only for filling oil (this is a drain plug, indicated by a red arrow) and for draining (this is a drain plug, indicated by a blue arrow), remember them correctly, because when reading the article, we will not point them out in the photo, but simply say: turn the plug, unscrew the drain plug so that you need to know their location.
When do I need to change the oil in the rear axle gearbox?
There is no specific threshold for changing the oil because different manufacturers have different properties, some claim that the oil should never be changed (There are many claims that the oil should not be changed, as for the control mechanism, everything wears out over time and needs to be replaced ), but every oil has additives that reduce the wear of the gears, and their anti-corrosion characteristics turn out to be such that the gears do not rot, so after a certain threshold the oil will reach 100. I have to change this from the gearbox to the rear axle . Then the oil was changed to 20,000–40,000 thousand km. mileage, depending on what we have already said about the properties of the oil, in addition to the operation of the car (where it is driven), you also need to look, for example, if you live in a rural area where there is one dusty and dirt road where you should then slip in the rain, then the oil in this case needs to be changed more often, this also applies to cars that drive a little more and brake and then move again (in the city there are so many cars stuck in traffic jams at all times) and most likely the oil becomes unsuitable for movement, i.e., with high joint strengths (as many engines are spinning) and traction of different types of trailers.
In addition to the above, you also need to change the oil after the expiration date (it is indicated on the packaging and is about 5 years), since during this period all its characteristics and additives are lost and the oil is no longer called oil By the way, it is just a stupid fluid . There are also unscheduled oil changes that you have to do when buying a used car (of course) once you start driving the newest car (they just fill new cars with oil that is short enough to fill, they save so much and even more, that after it starts, it is necessary to change the oil, since all the parts are worn out, and during grinding they wear out a little, and all their wear must be removed by changing the oil), and this also applies to old cars, because if you put a new one, for example gearbox, after its mileage (2500-3000 thousand km) it is necessary to change the oil to remove all chips from the new gear. (Carry items, so to speak)!
How much oil is required?
Many owners of domestic cars are interested not only in what kind of oil to pour into the VAZ 2107 gearbox, but also how much of it is needed. It is important not only how much oil is in the box, but also how much of it will go into the transmission when replaced.
In cars with four-speed gearboxes, the gearbox contains only 1.35 liters of oil, and in the case of five-speed gearboxes the capacity reaches 1.6 liters.
Many VAZ 2107 car owners are interested in the question: how much oil should be poured into the main components of the car, such as the engine, gearbox or rear axle? In fact, this information is included in every vehicle operating manual that is issued upon purchase at a car dealership. But if you are the owner of a used vehicle or for some other reason do not know what the main filling capacities of important units are, then this information will be provided in more detail below.
Changing the oil in the rear axle gearbox of a VAZ-2107
In VAZ-2107 cars, the greatest load falls on the rear axle gearbox. But this is not a problem if the unit is correctly assembled, installed and maintained correctly, taking into account the manufacturer’s recommendations. This way it is possible to avoid breakdowns and extend the life of the node. As a result, the gearbox lasts longer than even less loaded vehicle devices.
Based on the information in the instructions, the oil in the gearbox (for the rear axle and gearbox) is changed after the break-in is completed. The next time such work is performed is after 2000 kilometers, and then once every 60 thousand kilometers.
A design feature of the rear axle gearbox on the “seven” is the presence of a special type of hypoid transmission with shifted axles. Thanks to this engagement, it is possible to reduce noise during the grinding period of surfaces. But there remains a risk that the appearance of sliding along the contact line of the teeth can lead to jamming. To eliminate this effect, it is worth using a special transmission oil that contains extreme pressure additives. This lubricating fluid belongs to the GL-5 class, and its name is Hypoid.
To change the oil in the gearbox, you will need 1.35 liters. The operating algorithm is the same as when pouring new oil into the G7 gearbox. The optimal time for carrying out the activities in question is before the start of summer or winter. This is due to a special approach to the selection of oil, which should be selected taking into account viscosity. So, when operating a machine in cold conditions, a lower viscosity is required, and in the summer, when it is hot outside, a higher viscosity is required.
Oil change process
Except for the cases described in the maintenance card for the “seven”, changing the oil in the gearbox is necessary in the following situations:
- Appearance of silvery dust in the oil. If there is not dust in the oil, but small grains of metal, this indicates a serious breakdown of the machine. In such a situation, a regular replacement is not enough.
- The oil has turned black or coffee-colored. This problem indicates that moisture has entered the oil and the additives present in the oil are destroyed.
Replacing the lubricant in the rear axle gearbox is easy. If you follow the recommendations in the article, you can do the work yourself. Please note that the oil is drained after a trip. This is due to the fact that the liquid, in this case, is heated and comes out of the crankcase better. Be careful when doing this, as the oil can reach temperatures exceeding 90 degrees Celsius.
The algorithm of actions when changing the oil in the gearbox is as follows:
- Using a 17" key, unscrew the plug installed in the oil filling hole.
- Place an empty container in the area where the liquid will approximately drain.
- Take a twelve-socket hex wrench and unscrew the drain plug. This will remove the old oil.
Checking the level and condition of the oil in the gearbox
The level and condition of the oil in the gearbox is checked “cold”, when all the liquid collects in the crankcase.
The oil should be at the level of the filler hole, 2-5 millimeters below. To check, unscrew the filler plug and use a stick, wire, finger, or other improvised means to find out the level. The condition can be checked here by taking a small amount of liquid with a syringe and tube.
You can also assess the condition of the lubricant by unscrewing the drain plug for a few seconds. Tighten the filler first, so the oil will flow much more slowly. If the car has been sitting for several hours before, all foreign particles will settle in the crankcase, and you will get a clearer picture of the condition of the oil.
The presence of metal particles in the waste indicates that the gearbox components have a high degree of wear, and serious repairs and replacement of parts may soon be necessary.
Why do you need to change the oil?
As you know, the engine is the heart of any car. And the heart cannot function without blood. In this case, the blood is motor oil, which lubricates moving parts and also cools various components in the engine.
Over time, such a lubricant loses its characteristics, becomes dirty and cannot effectively cool the engine, which leads to various serious breakdowns. To prevent such problems with the engine, the VAZ 2107 oil change should be carried out every 15 thousand kilometers. Moreover, if the car is used in the city, it is best to reduce the service interval to 10,000 miles.
When to change the oil in the gearbox and axles of a VAZ 2107
The recommended oil change interval for the gearbox and axles of the VAZ-2107 is from 30 to 40 thousand km, depending on operating conditions. Thus, an early oil change may be required in difficult climatic and road conditions, frequent off-road trips or in traffic jams, which often cause sudden starts and braking, which leads to overheating of the transmission. In such conditions, it is necessary to check the condition of the oil as often as possible, which in a spoiled state has the following signs: cloudiness, blackening, insufficient level, specific odor or thick consistency.
Stages of replacing lubricant VAZ 2107
On classic Lada cars or the more familiar Zhiguli, a convenient drainage of used oil from the engine is provided. The oil filter is also easily accessible and can be reached from the engine compartment.
During the production of the VAZ 2107, a large number of modifications were produced, which were equipped with various engines. Experienced drivers note good maintainability, unpretentiousness in maintenance, as well as consumables.
Before starting to replace the lubricant, precautions should be taken. It should be noted that the drained waste will be at a high temperature. Since the replacement is carried out on a warm engine.
How much gear oil to fill in a classic gearbox
I think that every car owner knows very well that today there are VAZ 2107 models with both 4 and 5-speed gearboxes. Of course, the level of these two boxes is slightly different.
Of course, it is necessary to pour a little more into the 5-mortar for reasons that are understandable to everyone.
- 5-speed gearbox - 1.6 liters
- 4-speed gearbox - 1.35 liters
According to the manufacturer's regulations, service changes of engine oil on the VAZ 2107 are carried out after 8,000-10,000 kilometers or at intervals of 1 year. But some car owners consider this interval to be a little too high, recommending that it be shortened taking into account operating conditions.
When using this car in winter, you should select oil taking into account the climate zone, as well as the recommendations of AvtoVAZ. Viscosity 5W-40 will allow you to operate the car down to -30°C, and 0W-40 up to -35°C.
What kind of oil
Mineral or semi-synthetic oil with all-season viscosity SAE 75W-80, 80W-85, 80W-90 or 75W-90, which is most suitable for Russian operating conditions, is poured into the gearbox of a VAZ-2107 car. In addition, you still need to make the best choice in favor of a manufacturer with a good reputation: Mannol, Total, Eneos, ZIC, Castrol, Kixx, etc.
Also, when choosing an oil, pay attention to the current tolerance indicators API-GL-3, 4 or 5. The higher the indicator, the more oil additives. In the case of a VAZ-2107 with high mileage, you can limit yourself to API-GL-4 approval, and owners of cars from recent years of production can use GL-5. Below are suitable oils for the VAZ-2107 gearbox.
- Castrol Syntrans Transaxle 75W-90 API-GL-4
- Lukoil Transmission TM-5 GL-5 75W-90.

Leaks and problems
The higher the mileage of the VAZ 2107, the more problems appear, as in principle with any car. Most often this is due to natural wear and tear of the engine, causing oil to burn. Although the manufacturer allows for a small consumption.
There can be many reasons why an engine eats oil. And in each case they can be individual. But, over the years of the model’s existence, we can talk about the most common places where leaks occur.
If the breather is spewing or throwing oil, or if there is oil in the exhaust manifold, this may indicate a serious problem with the oil rings. In this case, you can try decoking with dimexide. But it is better to use special auto chemicals designed for these purposes.
A leak from under the valve cover may be due to a worn gasket. Sometimes simply replacing the gasket does not solve the problem. Since the cover itself may have significant curvature. Therefore, in some cases it will have to be replaced.
A white emulsion in the engine or on the oil filler cap may indicate condensation. This is a common occurrence when temperatures change from minus to plus, mainly in autumn or spring.
But if the emulsion is also observed on the dipstick, then this is already a sign of more serious problems. Most often we can talk about a broken cylinder block gasket. And in rare cases, a cracked cylinder head may be to blame.
Also, with this problem, you can find oil in the expansion tank. Sometimes, simply replacing the gasket is not enough. It may be necessary to grind the head itself, and this is completely different money for repairs.
Step-by-step instructions for changing the oil
- Before you begin directly replacing the technical fluid, you should warm up the car engine to operating temperature. After this, we drive the car onto an overpass or lift, turn off the engine and place a container with a volume of about 4 liters under the oil pan.
- Open the hood and unscrew the filler cap, which is located on the valve cover, by hand.
- Next, use a 12mm wrench to unscrew the drain plug, which is located on the engine sump. Proceed with extreme caution, as you can burn yourself on the hot lubricant.
- We wait until the technical fluid has completely drained from the engine, after which we can begin further work. As a rule, this takes about half an hour. Remember that if you do not unscrew the filler cap, this will create increased pressure in the system, which prevents oil from flowing out of the drain hole.
- The oil filter can be unscrewed either using a special wrench or a screwdriver, which pierces its body and acts as a lever, which allows you to unscrew the filter from the thread. Be careful as there may be a small amount of grease in the filter element. If you do not have a puller, you can try to unscrew the filter by hand. Just be careful, as you can get burned on a hot engine.
- We screw back the drain plug in the oil pan and install a new filter element. It is necessary to pour a small amount of oil into the filter, and also lubricate the existing rubber O-ring. The oil filter must only be tightened by hand.
- After tightening the drain plug and filter, you can begin to pour oil into the engine. This is done through the filler plug on the valve cover. Fill in about 3 liters and wait 5-10 minutes, which is necessary for the oil to settle and check its level with a dipstick. The oil level should be between the corresponding marks on the dipstick.
- We start the engine, at this time the oil pressure light should light up, then go out after 5-10 seconds. The engine should run for several minutes, then turn it off and wait about 20 minutes.
- We check the oil level with a dipstick, as well as the oil filter and plug for leaks. If necessary, add oil to the average level on the dipstick.
This completes all service work. Every car owner can perform such engine maintenance. At the same time, he will save several thousand rubles that he would have paid at a service station for such an oil change.
Required oil level in the VAZ 2107 engine crankcase
Absolutely all engines that were installed on the “classic” until recently have the same filling tanks. So, for example, the engine oil should be 3.75 liters. It is not always possible to mark this level yourself, since not every canister has a transparent scale. Therefore, you also need to navigate using the dipstick. Each dipstick has special MIN and MAX marks, which indicate the minimum and maximum permissible oil level in the internal combustion engine. It is necessary to fill until the level is between these two marks, approximately in the middle.
Roughly speaking, when changing the oil in a VAZ 2107 engine, you will need a canister with a volume of 4 liters, since it will be drained almost completely. In many service stations, when refueling, auto mechanics fill the entire canister, since 250 grams do not play a special role, provided that they are more than the recommended value.
The process of changing VAZ 2107 oil in the rear axle gearbox
One of the most loaded structural units in the VAZ 2107 vehicle is the rear axle, or rather its gearbox. However, it can serve for quite a long time if it is assembled and installed correctly. Equally important is timely maintenance and proper operation of the vehicle.
In accordance with the instructions, the oil composition in the rear axle of the VAZ 2107 model should be replaced immediately after break-in, even later - after the mileage is at least 2,000 km, and subsequently at intervals of 60,000 kilometers.
It is important to know that the VAZ 2107 gearbox contains a special type of hypoid transmission coupled with offset axes. This type provides a reduction in noise levels during the grinding of elements, however, the sliding that appears along the teeth can often lead to the risk of jamming, but this, however, can be eliminated by a special transmission oil fluid.
Changing the oil in a VAZ 2107 gearbox: how to do it yourself
General view of the rear axle gearbox of the VAZ 2107
The most loaded unit in a VAZ 2107 car is the rear axle gearbox. But with proper assembly, installation and timely maintenance, it can last longer than even less loaded components. As the instructions indicate, the oil in the rear axle gearbox and gearbox should be changed after break-in, then after a run of two thousand kilometers and subsequently every sixty thousand kilometers.
The design of the gearbox of a VAZ car uses a special type of hypoid transmission with offset axes. This engagement reduces the noise level when grinding surfaces, but the sliding that occurs along the contact line of the teeth can lead to the risk of jamming.
Using special gear oil in the gearbox can eliminate it. The mixture contains extreme pressure additives, class GL-5. This oil is called Hypoid. The volume of oil poured into the gearbox is 1.35 liters. Changing the oil in the rear axle gearbox of a VAZ 2107 is carried out according to the same algorithm as the gearbox oil.
Changing the oil in the rear axle gearbox of a VAZ
In addition to the recommendations provided in the vehicle maintenance card, you can change the oil yourself in the following cases:
- There is silver dust in the mixture. If instead of dust there are metal grains, this indicates serious damage to the car. Just changing the oil is not enough.
- Coffee or black oil color. This indicates that water has entered it or the additives in the solution have been destroyed.
- You can change the oil in the VAZ 2107 axle gearbox yourself.
Tip: The oil should be drained after the car has been driven so that it is hot and drains well from the crankcase. But you need to be careful, the temperature of the liquid can reach 90 degrees.
Determining the oil level in the gearbox
If we talk about the volume of liquid poured into the gearbox, it is 1.35 liters. The algorithm for replacing the oil composition in the rear axle is in many ways similar to the algorithm for replacing the oil composition of the gearbox.
It is recommended to change the oil fluid before operating the vehicle in both the winter and summer seasons. By the way, the viscosity of the composition is different for these periods: in winter the consistency is more liquid, in summer it is more viscous.
Before replacing the oil composition in the rear axle of a VAZ, you can determine the fluid level in the gearbox. To do this, you will need a container with a volume of slightly more than 1.5 liters.
The next stages of work look like this:
- First of all, you need to put the car on the inspection hole;
- Next, you should clean the dirt from the drain and filler plugs;
- Using a 17 mm socket wrench, you need to unscrew the plug covering the filler hole;
- Next, you should check the oil fluid level using a suitable tool, for example, a screwdriver - the fluid level should reach the very bottom of the filler hole;
- If the oil fluid level does not reach the lower edge, you need to add transmission fluid using a special syringe, and then tighten the hole well using a plug.
Checking the oil level
Control checks of the fluid volume in the gearbox should be carried out every 10 thousand kilometers, as well as when malfunctions or visual leaks occur. Checking the oil level in the rear axle is quite simple. To do this, you will need a container with a volume of about one and a half liters, a 17mm wrench and a screwdriver. The next steps are:
- the car is placed on a viewing hole, overpass or lift,
- the filler plug is cleaned of dirt,
- use a 17 wrench to unscrew the filler plug,
- The oil level is controlled with a screwdriver: the liquid should reach the edge of the hole.
If there is insufficient protective liquid, it is necessary to add it using a syringe or other device.
Procedure for performing work when changing the oil
To ensure the speed and efficiency of the process, it is recommended to change the fluid in the rear gearbox immediately after the vehicle has been driven - this technique will warm up the oil and help drain it from the crankcase faster, also along with various suspended particles accumulated in the rear axle.
The algorithm of actions when changing the oil in the rear axle of a VAZ is as follows:
- First of all, it is necessary to drain the used oil fluid - to do this, you need to remove the plug at the drain hole located at the bottom of the crankcase. After this, when the liquid is drained, you need to screw the plug back. If you decide to drain the consumable immediately after warming up the car, you must be careful, because the oil temperature can reach very high levels;
- Before adding oil, make sure that dirt is removed from the gearbox. If the drained liquid is colored black and contains impurities in the form of metal filings, which indicates that the gearbox is not working properly, you must first wash it with viscous oil. This type includes spindle oil, which for flushing requires pouring into the gearbox in a volume of about 1 liter. After this, one of the rear wheels is hung out, and the engine is started. Next, you need to engage the very first gear - and, after a short period of time (about a minute), the engine can be turned off and the flushing composition can be drained;
- Next you need to unscrew the filler plug. Afterwards, using a specific syringe, you need to fill the gearbox on the rear axle with new transmission oil. You should carefully consider the level of the poured composition - it must correspond to the lowest level of the edge located at the hole. After this, when the liquid is poured in, you need to screw in the plug;
- Next, you need to check whether it is worth cleaning the breather from dirt. It is needed in order to relieve excess pressure inside the gearbox, which is obtained due to heating of the oil composition.
Steering of a VAZ 2107 car
On the VAZ 2107 model, the steering has a safety design with an articulated-lever steering wheel drive and a worm-roller gearbox.
- The steering gearbox is secured with three bolts in the engine compartment on the left side member.
- An adjusting screw installed on the top cover of the gear housing can be used to adjust the gap in the engagement of the double-ridge roller and the worm built into the structure of the device.
- Approximately 0.2 liters of oil is poured into the steering gear housing.
- To fill the oil, there is a filling hole on the top cover of the gearbox housing. There is no hole for draining the oil; fluid is only added to the VAZ 2107 if necessary.
Filling oil in the steering gearbox
Before adding oil, check the oil level:
- The vacuum booster is removed.
- Using a key set to “8”, unscrew the plug for filling oil into the gearbox, which has a conical thread.
Unscrewed plug from the filler hole of the steering gearbox
- A special rod is used to check the oil level. To do this, the rod is inserted all the way into the gearbox, as shown in the photo .
Checking the oil level
- From the top edge of the filling hole, the oil level should be at a depth of 15 millimeters.
- If you need to change the oil in the steering gear of a VAZ 2107, then use a spanner wrench to “13” to remove the four bolts that secure the lower cover of the gearbox.
- Just slide the lid and pour the oil into the container.
- The cover is put in place, secured with bolts and new oil is poured.
- The plug is screwed into the filler hole.
Results
Changing the oil in a VAZ 2107 axle is a responsible task that helps extend the service life of the vehicle, coupled with timely maintenance. In addition, such a procedure can indicate a malfunction of the gearbox - if you fix it on time and operate it correctly, it can last for quite a long time. It is recommended to adhere to the timing of oil changes in the gearbox. With the right approach, replacing the oil composition of the rear axle gearbox of a VAZ 2107 can be done on your own.
How much oil to pour into the gearbox and axle
First generation 2107, 1982-2012
Compared to its predecessor 2105, model 2107 was distinguished by its original design of the radiator grille and rear lights. New front seats and an improved instrument panel with tachometer were also installed. The quality of the interior trim has improved slightly, resulting in more comfort. At various times, the VAZ-2107 engine range consisted of gasoline carburetor engines with a volume of 1.3 and 1.5 liters, as well as a more modern injection engine with a volume of 1.5 liters. For some time, a version with a rotary piston engine was offered. In 2008, a modification appeared with a 73-horsepower 1.6-liter engine equipped with distributed injection. The production of the “Seven” was carried out at the IZH plant until 2012. The total production volume of VAZ-2107 was 3.1 million units, including Egyptian-assembled cars (until 2013).
