The steering mechanism of a car consists of a steering wheel, a shaft, a gearbox, rods, a trapezoid, a pendulum and steering knuckles.
Due to the steering gear, which transmits forces from the steering wheel to the rods, the front wheels of the car rotate at a given angle.
Transmission oil poured into the steering system helps ensure stable operation of the gearbox and reduce wear on its parts. If it leaks, which occurs regardless of the condition of the gearbox, and untimely replacement occurs, the problem of dry friction in the unit arises. As a result, the quality of driving deteriorates, the rotation of the steering wheel becomes difficult, and its play increases.
Let's take a closer look at what oil is used for the VAZ 2107 steering gear, how to check its level and replace it.
Operating principle of the steering gear
The VAZ 2107 is equipped with a worm-type steering gear. The principle of its operation is as follows.
The driver turns the steering wheel. The worm shaft is driven by cardan joints. It rotates, moving the double-ridge roller. Then the secondary shaft rotates, on which the bipod is fixed, driving the steering rods.
The trapezoid moves the steering knuckles, turning the wheels in the desired direction.
To reduce friction of the internal elements of the steering gear, transmission oil with a viscosity grade of SAE 75W-90, 80W-90 or 85W-90 is poured into the mechanism. The filling volume of the VAZ 2107 gearbox is 0.215 liters.
Influence of viscosity grade
If the VAZ-2107 will be operated in temperate climate areas, where summers are constantly hot and winters are quite cold, then it is recommended to fill the manual transmission with all-season transmission fluid - SAE75W90. It can operate in a wide temperature range (-40/+45). Moreover, the performance qualities of the oil always remain unchanged.
When purchasing lubricant for manual transmission, you must take into account your place of residence. Each region has its own climatic conditions.
For example, SAE 80W85 can be operated in the range from +35 to -26 Celsius. Some regions require a wider range, so it is important to consider these values when purchasing.
How to check the oil level in the gearbox?
To avoid premature failure of the steering gear, the oil level in it must be periodically checked, topped up or completely replaced with lubricant.
The VAZ 2107 gearbox is located in the engine compartment on the left side, under the vacuum brake booster. Checking the oil level is done as follows: Using a 8 wrench, unscrew the filler plug. A screwdriver or similar tool is lowered into the crankcase. Normally, the lubricant should reach the bottom edge of the filler hole.
If the oil level is lower, top it up (using a syringe). The crankcase is filled until lubricant begins to flow out of the filler hole.
At the end of the work, tighten the plug and remove any leaks from the gearbox.

If you solve the problem, please write back. And so the advice is to lift the front of the car with jacks and try to turn the steering wheel
I also heard that the steering rack from the VAZ 2110 is put on high quality.
I poured an engine additive into the column and the steering became a little lighter.
Check the pendulum on the right side, they sometimes jam. When I changed mine, I couldn’t turn it by hand, which couldn’t be said about the new one.
Oil is not the reason, the main thing is the level, and what kind is not important, even engine oil, as long as there is some kind of oil.
Level at the top filler plug
Strengthen your arm muscles. Seriously. Nothing else can be fundamentally changed. I drove different cars, including various Zhigulis and PP Vases. Well, you can’t do anything with a system like a globoidal worm. This steering mechanism is reliable, but generally tight. The most effective tuning method is installing an EUR. But it's difficult and expensive. Good pressure in the tires of the front wheels will make driving a little easier, oddly enough. Well, replacing the pendulum, of course.
Oil change process
The oil in the VAZ 2107 steering gear should be changed once every one and a half years or every 50-60 thousand kilometers.
All work is carried out in a viewing hole or overpass, wearing special clothing and rubber gloves.
Before you start changing the fluid, warm up the engine to improve the fluidity of the lubricant.
Prepare a metal brush to clean the surface of the gearbox, two large-volume syringes and a small piece of washer hose (or a dropper tube).
Clean the hood and the surface of the gearbox from dirt (especially in the area of the filler hole). Find the filler plug - it is located near the adjusting screw in the middle of the top cover. Remove the plastic plug from it, unscrew the plug itself using a 8mm wrench.
Place a piece of tubing on the syringe and pull out the old oil.
Using a second clean syringe, fill the gearbox with new lubricant to the required level. In this case, it is recommended to rotate the steering wheel, so it is better to carry out the replacement with an assistant.
At the end of the procedure, tighten the filler plug and wipe off any traces of oil.

Lubricant selection
When choosing oil for a VAZ 2107 gearbox, you should take into account the compatibility of the fresh product with the used one - especially when filling in new fluid without flushing the crankcase.
The manufacturer recommends using transmission fluids of the GL-4 or GL-5 group. The former contain a high concentration of additives, the latter are used to lubricate rubbing gears.

Flushing the gearbox
When switching to another transmission oil, after purchasing a used car, or when undergoing scheduled repairs, it is recommended to flush the steering gear.
To do this, mix transmission or motor oil with diesel fuel in a 3:1 ratio.
The mixture is poured into the system after removing the old oil, then jack up one wheel, start the engine and leave it running at first speed for a few minutes. After this, the washing is drained.

Peculiarities
If extraneous sounds and knocking noises appear in the steering gear, which are felt through the steering wheel, you should think about changing the oil, because this is the first sign of a malfunction of the mechanism. You should also be careful and hurry up with repairs in cases where turning the steering wheel becomes difficult, various sounds and noises occur constantly or periodically. If there is obvious play in the steering gearbox, you may notice an oil leak. If you identify at least one of these signs, you should not waste time, you need to urgently repair the mechanism or seek help. Neglect of this kind of malfunction will not lead to anything good, because the loss of the ability to control a car can have unpredictable consequences, not only for the driver, but also for other road users.
UAZ Patriot refueling tanks
The design of absolutely every modern car necessarily requires the presence of a power plant, tank, gearbox, and other units and various parts that have their own volumes. It is in these same volumes that diesel fuel is placed, as well as brake fluid, of course, gasoline or antifreeze, but all the fluids listed for each individual model are individual. We invite you to learn in detail about the filling tanks on the UAZ Patriot, which is popular in our country, plus we’ll look at what they essentially are and how much this car model requires to fill certain mechanisms.
A little about the oil hose in the Patriot
This main element serves to connect the pump to the steering mechanism
It is not famous for its reliability, so the owner needs to pay special attention to it. If the driver notices a delayed reaction of the wheels to the rotation of the steering wheel, which can be especially pronounced at speed, then this should be a signal to check and subsequently replace the hose
“Thanks to” low-quality manufacturing materials, this hose tends to swell after a certain mileage, which means a loss of pressure in the system.
This state of the element can provoke a rush, which is a prerequisite for an emergency situation. Here the driver needs to have a spare hose with him. Purchasing it is not a problem, the main thing is to know the article number - “3163-00-3408150-01”. This version of the product has gained support from many owners. After replacement, the system will need to be bled. This will remove any remaining air in the circuit. The hose “3163-00-3408150-01” is shown in the photo.
Different types of oils
Dexron
- a separate class of ATF fluids from General Motors, produced since 1968. Dexron is a trademark, produced both by GM itself and by other companies under license.
ATF
(Automatic Transmission Fluid) - oils for automatic transmissions, often used by Japanese automakers and in power steering.
P.S.F.
(Power Steering Fluid) - literally translated as power steering fluid.
Multi HF
