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.
What kind of oil to fill
at the VAZ 2107 checkpoint?
In today's article we will help you figure out which oil is best suited for the VAZ 2107 gearbox and how much is needed to replace it? Such questions are often asked by the owners of these domestic cars, so who should know these subtleties.
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.
- 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.
- 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.
1. Unscrew the filler plug of the rear axle. 2. Place a container with a volume of at least 1.5 liters under the drain hole of the rear axle. 3. Using a 12 mm hex wrench, unscrew the drain plug of the rear axle. 4. Drain the oil from the rear axle of the VAZ 2107. The drain plug is equipped with a magnet that attracts wear products from the gearbox parts. 5. Clean the drain plug and install it back into the rear axle of the VAZ 2107.
Note If the drained oil from the rear axle on a VAZ 2107 is dark and metal particles are clearly visible in it, it is recommended to wash the rear axle gearbox on a VAZ 2107.
To flush the rear axle gearbox on a VAZ 2107, fill in approximately a liter of low-viscosity oil (for example, spindle oil). Having hung one of the rear wheels (see “Wheel of a VAZ 2107 - replacement”), we start the engine of the VAZ 2107 and engage first gear. After five minutes, turn off the engine, drain the oil from the rear axle, clean it again and tighten the drain plug. 6. Fill the rear axle to the level of the filler hole with fresh transmission oil and tighten the plug. 7. Clean the outside of the breather with a brush or rag. We turn the breather cap several times to clean its channel.
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
Preparation for replacement and necessary tools
So, changing the oil in the rear axle of a VAZ 2105 or another car is most conveniently done in a pit or overpass. Think in advance where you can find them. Buy oil for filling - you should take 2 liters - there will be a little left for topping up.
Advice! Before changing the oil, be sure to warm up the car by driving it for about 10 kilometers. This way the oil will drain better.
What tool will you need:
- Hexagon 12
- Socket wrench or 17mm socket with wrench
- Oil syringe
- Containers for waste oil
- Rag
- Rubber gloves to prevent oil from burning your hands
As you can see, changing the oil in the axle of a VAZ 2104 and other cars does not require any special costs and can be done with your own hands.
Changing the oil in the rear axle gearbox of a VAZ
- There is silver dust in the mixture. If there are metal grains instead of dust, this indicates serious damage to the car. You can't get by with just an oil change.
- 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.
Work order
So:
- Unscrew the plug in the hole for filling the oil with a key “17”.
- Place a container under the drain hole to collect used oil.
. - Use a hex wrench to “12” to unscrew the drain plug to remove the used oil.
- After the liquid has completely drained, the drain plug is screwed into place.
Advice: If the oil drained from the gearbox housing has a dark color or metal particles, the rear axle gearbox must be washed.
- To flush, you need to fill in about one liter of a mixture of thirty percent kerosene with gear oil. Instead of kerosene, you can use diesel fuel.
- One rear wheel is lifted, first gear is engaged and the engine is started.
- After three minutes, the washing mixture is drained.
- For filling, it is better to use an oil blower or a lever grease gun. If you don’t have them on hand, you can use a large plastic syringe with an elastic tube attached to its end.
- 1.3 liters of special transmission oil is poured into the gearbox.
- It is necessary to ensure that its level reaches the lower edge of the filler hole.
After filling the oil, the breather is checked and cleaned of dirt. This device is necessary in order to relieve excess pressure in the gearbox that is formed when the oil heats up and when its level rises. All operations for changing the oil on a VAZ 2107 car can be clearly seen in the video.
Viscosity grades
To choose which gear oil
better for the VAZ 2107 you need to decide on the viscosity class:
- SAE75W90. This class includes semi-synthetic or synthetic oils that are suitable for all-season use. The lubricant can be used within the range from 40 to 35 degrees Celsius. Such oils can be used in cars that are operated in the harsh conditions of our country.
- SAE75W85. This viscosity class is also suitable for all-season use in a box, and the temperature for maintaining performance characteristics varies from 40 to 45 degrees.
- SAE80W85. Oils of this viscosity boil at 35 degrees and freeze at 30 or more.
What kind of oil to fill in the VAZ 2109 in winter.
Change of oil
Let's look at the detailed process of changing the oil in the rear axle; Changing the oil in VAZ 21213 axles will also be considered.
Rear axle
So, we begin to change the oil, having previously prepared everything necessary and warmed up the car sufficiently:
- First, drain the old oil. To do this, take a 12mm hexagon and unscrew the drain plug. This is where rubber mittens or gloves come in handy. Oil, if there is any, of course, will flow sharply from the rear axle onto your hands.
And it will flow straight onto your hands, so you better be careful.
- After unscrewing the drain plug, place a container for oil. After the oil has drained, clean the magnet on the plug to prevent metal shavings from getting into the new oil and screw it back into the housing.
- Now add oil. Using a 17 key, unscrew the filler plug (as in the photo). Fill the syringe with oil and pour it into the reducer. Oil should be filled to the level of the filler neck hole.
- Once the required oil level is reached, the filler plug is screwed into place.
- Next, wipe everything with a rag and check the tightness of all threaded connections.
Note! Tighten both plugs without being too fanatical. Still, it will be unpleasant to mess with the repair later.
That, in fact, is the entire oil change in the VAZ 2105 axle.
Front axle
On Niva and Taiga cars, in addition to the rear axle, there is also a front axle, since the cars are all-wheel drive. Note that changing the oil in the VAZ 21214 axles is no different from replacing the oil in the rear axle on other models. The tools are the same, the tips are the same, the device is similar, and the process is identical. First, drain the oil from the gearbox. We tighten the drain plug and unscrew the filler. Fill the oil to the level. We control the tightness of connections. That's it. Everything is ready.
Many car owners do not think that their car also needs to be looked after, and not just repaired. If you not only change the oil of the rear axle of your VAZ 2106, but also take care of the car yourself, then repairs can be carried out much less frequently. Here are some oil tips.
Tip 1 - check the oil level! How often should I check? After 20,000 km of your car's mileage, look at the rear axle. Unscrew the filler plug and check the oil level with your finger. If necessary, add oil to the level.
Tip 2 – change your oil on time! According to repair manuals, the frequency of oil changes in the rear axle of VAZ cars is 60,000 km. By following this advice, your gearbox will last longer.
And a little more about. The price for this operation is quite low, so in order to save time, you can pay the guys at the service station for a replacement. By the way, some service stations provide free oil changes when you purchase it in their store - pay attention.
Change transmission oil
in
the gearbox
(
gearbox
) and
rear axle gearbox
it is recommended every 35,000 km or after three years of vehicle operation.
It is also advisable to check the level and condition of the transmission oil
immediately after purchasing a used car.
The oil should be changed if: the oil in the gearbox housing
and
gearbox
is below the recommended level, there is silvery dust in the oil (precisely dust, if you find metal particles in the oil, then it is most likely too late to change the oil and you need to prepare for serious repairs), The color of the oil is black or coffee (which may indicate the destruction of additives in the oil or water entering the oil).
And, of course, you can change the oil in both the gearbox
and
the rear axle gearbox
on your own! How to do this and what you will need for this, read on...
Changing the transmission oil in the gearbox and gearbox
It is best to do it at the same time and immediately after the trip (at least 5 km so that the oil warms up). Plus, you can immediately buy 3 liters of 80w90 oil - 1.3 liters for the gearbox and 1.4 (1.6 for a five-speed) liters for the gearbox and still have some left over for lubricating locks, etc.
Next... It is better to change the oil in an inspection pit or overpass. And the main thing I want to say right away. The problem may be caused by the stage of pouring oil into the rear axle gearbox.
and, especially, into
the gearbox
.
An oil blower (photo 1) or a lever grease gun are best suited for this. But, since these devices may not be at hand, you can replace them with a large plastic syringe plus an elastic tube tightly fitted to its end. Also, to fill the gearbox with oil,
you can use a structure - a long rubber hose (one end of the hose is in the gearbox, the other is brought up into the engine compartment) and a watering can (inserted into the end of the hose that is brought out into the engine compartment). The only disadvantage of this method is that the oil needs to be warmed up or replaced in the summer.
Tools: socket wrench set to “17”, hexagon to “12”, container for draining old oil.
We change the oil in the gearbox of VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107
:
- First, unscrew the drain plug (photo 2K) (usually a hex wrench set to “12”) and drain the oil into a previously prepared container. After this, you can unscrew the filler plug (photo 3K) (key to “17”).
- Let the oil drain well and tighten the drain plug.
- We select one of the injection methods (oil blower (photo 4K), a large syringe or a filling funnel plus a rubber hose) and pump the transmission oil to the lower edge of the filler hole (in general, fill until it flows). And tighten the plug.

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 units. 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. Replacement must be made before operating the car in winter and summer. For these seasons, the oil has a different viscosity. In winter it is low, and in summer it is high.
