The process of changing VAZ 2107 oil in the rear axle gearbox

The rear axle gearbox of the VAZ-2107 is a complex device with the help of which crankshaft revolutions are converted into rotation of the rear wheels. The drive axle is fixed to the car body using rods. For reliable operation of the gearbox, a special lubricant is provided, which protects mechanical parts from premature wear. This device operates under large temperature differences and constant high load. Therefore, to protect surfaces, a special oil with enhanced protective properties is required.

How to change the oil on the rear axle of a VAZ 2107

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.

When replacement may be needed

The lubricant loses its properties over time. The oil in the bridge must be changed regularly, according to the instructions. But during operation, signs of malfunctions may appear, which indicate the need for a faster change of waste fluid:

• whistling and noise appear from the side of the bridge;
• when the nature of the load changes, knocking noises become audible;
• There are drips and traces of oil fluid on the gearbox.

The car care instructions state that in the VAZ-2107 the rear axle oil is changed for the first time after running in (2000 km). And then it needs to be changed every 60 thousand kilometers. But, given the difficult climatic conditions with ultra-low temperatures, bad roads and constant driving in city traffic jams, it is recommended to fill in new oil after 30 - 35 thousand kilometers. Unscheduled maintenance when purchasing a used car, major repairs are also accompanied by the replacement of lubricant.

The oil on the rear axle of the VAZ-2107 needs to be changed every 30 km

Experts advise changing the lubricant in different seasons (winter and summer). In winter, the oil composition should be more liquid, with a lower pour point. And in summer it is more viscous.

How much and what to fill in VAZ 2107

Fuel tank volume – 39 l. The manufacturer recommended using gasoline with an octane rating of 92 or 95.

The quality of operation of components and assemblies depends on the regularity of replacing lubricants. Engine oil lasts no more than 10 thousand km. After which it is necessary to change it to a new one. Lubricant fluid (with API quality level: SG, SH, SJ) is suitable for the VAZ 2107. During the procedure, a new oil filter must be installed. The same oil is used for the engine crankcase as for the power plant.

The service life of antifreeze is 60 thousand km. Even if the car is not used, the fluid loses its properties after two years, so it needs to be replaced.

The transmission oil is changed every 60 thousand km. At the same time, its level is periodically monitored. After 20 thousand km it may decrease, which will negatively affect the operation of the unit. The defect must be eliminated and oil must be added to the edge of the filler hole. This also applies to the rear axle housing. The gearbox filling volume is 1.6 liters.

Brake fluid should be replaced once every two years regardless of the vehicle's mileage. Domestic DOT-4 or a foreign equivalent is recommended.

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 key 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.

Oil change instructions

You can replace the gearbox lubricant in an inspection pit, overpass or lift. Before driving the car into the pit, you should drive a little and warm up the axle fluid. You should also prepare in advance a tool (a set of keys and screwdrivers), containers for working, protective gloves, rags, a special syringe or a device with a hose for pouring.

The old oil is poured into a pre-prepared container

Changing the oil in the rear axle gearbox of the VAZ-2107 is performed in the following order:

1. Clean the drain and filler plugs from any dirt.
2. Using a 12mm wrench, unscrew the drain plug.
3. Drain the old gear oil into the prepared container. Remember that the liquid will be hot after warming up.
4. Tighten the drain plug.
5. Unscrew the filler plug.
6. Pour in enough oil to reach the bottom edge of the hole.
7. Tighten the filler plug. Make sure there are no leaks.

If inspection of the used fluid shows severe contamination, then you need to rinse the gearbox before filling in a new one. To do this, mix transmission or motor oil with diesel fuel in a ratio of three to one. The resulting mixture is poured into the reducer. One wheel is lifted with a jack. The engine starts and first gear is engaged. This process takes several minutes. After this, the cleaning fluid can be drained and new drive axle grease can be added.

Oil in the gearbox - all the mechanisms that rotate and rub against each other need oil, the same with the gearbox, inside it there are gears (They are metal) that rub against each other during operation and if they are not lubricated with anything, they will quickly come out (They will become scuffed or even deformed and the gearbox will have to be replaced), and when lubricated they will rotate and rub against each other with much less friction and therefore the wear of the parts will be reduced (They will not fail so quickly) , in addition, the gears in the gearbox will also work more quietly and thus it will not hum and vibrate too much as it will if you completely drain the oil and start the car.

How much to fill (volume)

You won’t believe it, but there are also owners who don’t even know that the rear axle of a car also needs regular lubrication, although not as often as the engine. Also, there are drivers who believe that if the oil does not expel or ooze, there is no need to change it at all. This is all wrong and it is also necessary to perform this procedure, as in the internal combustion engine and in the gearbox.

The lubricant volume should be 1.3 liters. To fill the required level, you need to wait until the oil flows from the filler hole; this will be considered the optimal volume.

Replacement

The oil is changed according to the same algorithm as the oil in the gearbox, after a mileage, so that the oil is hot and drains better:

- unscrew the filler plug

— place a container for used oil under the drain hole

- unscrew the drain plug

- after the oil has completely drained, tighten the drain plug

- pour oil into the filler hole until oil flows out of it

Which one to pour?

It is recommended to fill the VAZ 2107 rear axle gearbox with transmission oil with a viscosity grade of 75W90 or 80W90 with API specification GL-4/GL-5. For example, CASTROL Syntrans Transaxle 75W-90 API GL-4 or Lukoil 80W90 GL-5.

In terms of volume, 1.5 liters of liquid is sufficient for replacement. Change at intervals of 30-40,000 km or every 3 years, whichever comes first.

The domestic car VAZ 2107 is a rear-wheel drive vehicle. The rear wheels are driven by the rear axle and cardan drive. An important role in this is played by the rear axle, which is a gearbox for converting torque from one value to another. This is the mechanism in which the gears rotate. Oil is used to reduce friction on these gears. What kind of oil is recommended to be poured into the rear axle gearbox of the VAZ 2107 will be discussed in this material.

Signs of gearbox problems

The rear gearbox is one of the reliable mechanisms of classic Zhiguli cars and breakdowns rarely occur with it. However, like any other unit, it may have its own malfunctions, which are determined by characteristic symptoms. They are worth dwelling on in more detail.

Noise when accelerating

If during acceleration there is an extraneous sound from the gearbox installation site, then it can be caused by:

• worn out or incorrectly adjusted differential bearings. It will require dismantling, disassembling and diagnosing parts with subsequent adjustment;
• Incorrect meshing of the teeth of the main pair gears. Eliminated by proper adjustment;
• lack of lubrication in the gearbox. The lack of oil in the crankcase is restored, after which it is checked for leaks at the places where the sealing elements are installed.

If noise occurs both during acceleration and during braking by the power unit, there may not be many reasons:

• deterioration or failure of the bevel gear bearings of the main pair. Eliminated by replacing failed elements;
• Incorrect adjustment of the gap between the tip and the planetary gear. The mechanism needs to be diagnosed and replaced with damaged parts, as well as setting the required gap between the gear teeth.

Why do you change the oil?

The rear axle gearbox is a mechanism that is subjected to a number of different loads. Through these loads, destructive actions occur. To avoid accelerated wear of gearbox parts, it is necessary to use a special lubricant. This lubricant is an oil that, during the operation of the gears of the mechanism, envelops them, eliminating accelerated wear and overheating, and also cleans the teeth from chips and metal dust.

It is necessary to change the oil in the rear axle gearbox for the simple reason that over time it loses its primary properties. When the gears rub against each other, thermal energy is released, the value of which is reduced with the help of a lubricating fluid. In addition, when the gears rub, the teeth wear out, resulting in the formation of chips and metal dust. If you do not change the lubricant in the gearbox for a long time, the amount of metal shavings and dust will only increase, which will lead to accelerated wear of the rubbing parts.

When to change gear lubricant

Changing the oil in the rear axle of a VAZ 2107 should be done regularly, but there is no specific threshold. It all depends on many different factors, but the manufacturer of a domestic car recommends performing this procedure every 60 thousand km.

Some of the main factors that influence the timing of oil changes are:

1. Driving character. Frequent and abrupt starts are not at all beneficial to the parts and mechanisms of the car, including the rear axle.
2. Vehicle operating conditions. If the car is used in rural areas where there are poorly paved roads, dust, and dirt, then replacement should be done more often.
3. Lubrication quality. It is recommended to fill the rear axle of the VAZ 2107 with special high-quality oil. If you pour low-quality lubricants into the gearbox, you will need to replace them much more often.
4. Operating a vehicle with a trailer. The wear of the device parts will accelerate if the car is operated with a trailer in which cargo is transported.

Features of lubricant selection

It is recommended to fill the rear axle gearbox of the VAZ 2107 with semi-synthetic gear oil. It should have viscosity parameters 75W-90. This is a universal lubricant option, which is usually poured into the gearbox.

Special gear oil in the gearbox improves the quality of parts and also reduces their wear. Not every G7 owner knows how much oil needs to be poured into the gearbox. The lubricant volume for the gearbox is 1.35 liters. It is poured through a special filler hole (on the side), using a technical syringe. You must first drain the old lubricating fluid, for which there is a special drain plug at the bottom.

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.

How much liquid and what oils are filled in LADA (VAZ-2107)

Lada VAZ 2107 is a domestic car with a long history. Despite the great competition, it does not give up its position and occupies a leading position in sales in the secondary market. Today, almost two million Russians own a S7.

The car is presented in a sedan body. Rear-wheel drive. The gearbox is mechanical. There are ten modifications. Their main differences are in power plants and restyling.

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:

1. 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;
2. 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;
3. 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;

4. 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.

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.

Oil for gearbox, transfer case and axles of VAZ-2107

VAZ-2107 is a rear-wheel drive small class sedan, produced from 1982 to 2012. During the years of the USSR, this car was considered the successor to the outdated family of VAZ-2101, 2102 and 2103 models, on the basis of which it was built. In addition to the 2107 sedan, the updated line consisted of the 2104 station wagon and the 2105 sedan, which, in comparison with the “top” 2107, had a basic level of equipment. In other words, 2107 is a modified version of 2105. The sedan competed with Moskvich and IZH cars. In post-Soviet Russia, the VAZ-2107 headed the “classic” family of VAZ cars, which was replaced by the Lada Granta in 2012.
