Changing the oil in the VAZ 2107 axle with step-by-step instructions, checking the level

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.

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.

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.

Timely oil changes in the main components of the VAZ 2107 will increase its service life without costly repairs. And the price for oil changes is acceptable for all car owners.

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:

Clean the drain and filler plugs from any dirt.
Using a 12mm wrench, unscrew the drain plug.
Drain the old gear oil into the prepared container. Remember that the liquid will be hot after warming up.
Tighten the drain plug.
Unscrew the filler plug.
Pour in enough oil to reach the bottom edge of the hole.
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
- tighten the filler plug

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.

Which oils are more suitable for the VAZ 2107?

In principle, any oil can be poured into the “seven”. The highest quality will, of course, be synthetic. Mineral water or semi-synthetic water will also not do any harm.

The cheapest is mineral liquid. However, it has a significant drawback - it begins to freeze quickly in cold weather. As a result, it is difficult to start the engine in sub-zero weather. You have to depress the clutch when starting the car.

Synthetics and semi-synthetics thicken less on cold days. However, their consistency has characteristic differences. Synthetics have high fluidity, which is why they are used in new manual transmissions. It begins to leak even with the smallest defect in the sealing gasket.

Semi-synthetic oil is thicker. Therefore, it is used in the manual transmission of a car that has covered more than 100,000 kilometers. If, after filling, the semi-synthetic material begins to ooze, then it is time to replace the failed parts.

Of course, each driver decides for himself which oil to use. But in any case, it is necessary to take into account all the nuances described above. Lubricant characteristics must comply with the manufacturer's recommendations. Replacement is carried out in accordance with the specified regulations. As a result, the gearbox will operate without repair for a long time.

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:

Driving character. Frequent and abrupt starts are not at all beneficial to the parts and mechanisms of the car, including the rear axle.
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.
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.
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.

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.

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.

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.

Which lubricant to choose

Many drivers have a reasonable question: what oil to fill? Mechanics recommend pouring oil into the rear axle gearbox of a VAZ-2107 with a viscosity of 75W90, 80W90 or another suitable one with API classification GL-4/GL-5. For example, Castrol 75W90, Lukoil 80W90. In winter, it is better to fill the rear axle of the VAZ-2107 with synthetics. In summer, mineral water.
