How much does the crosspiece cost for VAZ 2106 and 2107 and what does the price depend on?

VAZ 2106 and 2107 are the same cars as Renault or Honda. The only difference is that it is the brainchild of the domestic automobile industry. However, this does not mean that they cannot break. A machine is, first of all, a mechanism, each detail in which plays its own special role. Depending on the quality of the road surface, the chassis of any car wears out over time. That is why it is very important to know how much the crosspiece costs for the VAZ 2106 and 2107.

On average in Russia, the cost of this element for both cars is 350-400 rubles . Depending on the region, the price may vary.

What is it?

The crosspiece is a very important component of the driveshaft, which transmits rotation from the power unit to the rear wheels, and the “six” and “seven”, as we know, are rear-wheel drive. It helps to rotate the rotation coming from the gearbox by 90 degrees in order to rotate the wheels in the desired direction.

If the part is faulty, then the following symptoms may appear:

Clicking noise when starting.
Noise appears during sudden acceleration.
Heavy knocking or knocking noises when shifting gears.
Vibration at speeds over 80 km/h.
Presence of a squeak.

This chassis part consists of several components:

Needle bearing.
Thrust bearing.
Retaining ring.
Tylnik.
Sealing cuff.
Needle and thrust bearing cup.

Thanks to its cross-shaped shape, this part got its name.

What does the price depend on?

There are several different factors that influence the final cost of a given item. The first is characteristics . The crosspiece is a very important part that is constantly under influence, therefore its degree of wear is greater than that of some others. Therefore, there are two main types of crosses: reinforced and not. The first one will obviously be more expensive, but it will also last longer.

The second is a sample . It's no secret that VAZ has improved its cars over the course of its existence, changing some elements, which is why they produce old and new crosspieces. It is not recommended to install new crosspieces on the VAZ 2107, because this will significantly affect the rigidity of the hinges.

The third is the manufacturer. Obviously, car owners will only buy spare parts from a reliable manufacturer. Today, the best companies in the production of these spare parts are: GKN (Germany), VolgaAvtoProm LLC, AVTOVAZ OJSC.

Pricing factors

If you need to buy a new gearbox for a VAZ 2107, then you should first go to different places where this auto part is sold. This will help you purchase the part that is most suitable in all respects. Novice motorists often wonder about the wide cost range for the gearbox for the VAZ 2107.

Experts explain the price dispersion by the influence of the following factors on the price:

Quality.
Brand.
Originality.
Variety.
Place of purchase.
Delivery or installation required.
The reputation of the seller, his pricing policy.

Design and technical characteristics of the gearbox

The rear gearbox of the VAZ 2107 car consists of a massive steel casing with a shank, a driveshaft flange, two main gears mounted at right angles to each other and a self-locking differential.

The main elements of the gearbox are the housing, the main pair of gears and the differential with satellites

Rear gear ratio

The main characteristic of any gear transmission is its gear ratio. It is the ratio of the number of teeth on the driven gear to the number of teeth on the drive gear. The driven gear of the VAZ 2107 rear gearbox has 43 teeth. And the drive gear has 11 teeth. Dividing 43 by 11 we get 3.9. This is the gear ratio on the VAZ 2107 gearbox.

Another important point should be noted here. VAZ 2107 was produced for many years. And over the years, gearboxes with different gear ratios were installed on it. For example, the earliest models of the “seven” were equipped with gearboxes from the VAZ 2103, the gear ratio of which was 4.1, that is, the tooth ratio was 41/10. On later “sevens” the gear ratio changed again and was already 4.3 (43/10) and only in the newest “sevens” this number is 3.9. Due to the above reasons, the driver often has to independently determine the gear ratio of his car. Here's how it's done:

the car is set to neutral gear;
The rear of the car is raised using two jacks. One of the rear wheels is securely fixed;
After this, the driver manually begins to turn the driveshaft of the car. It is necessary to make 10 revolutions;
By rotating the driveshaft, you need to calculate how many revolutions the unfixed rear wheel will make. The number of wheel revolutions should be divided by 10. The resulting number is the gear ratio of the rear gearbox.

Bearings

The rotation of all gears of the gearbox is ensured by bearings. In the rear gearboxes of the VAZ 2107, single-row roller bearings are used on the differential, and the rollers there have a conical shape. Bearing marking is 7707, catalog number is 45–22408936. The price of a bearing on the market today starts from 700 rubles.

All rear gear bearings of the “seven” are roller, single-row, tapered

Another bearing is installed in the gearbox shank (i.e., in the part that connects to the cardan). This is also a tapered roller bearing marked 7805 and catalog number 6–78117U. Standard VAZ shank bearings today cost from 600 rubles and more.

Planetary pair

The main purpose of the planetary pair in the rear gearbox of the VAZ 2107 is to reduce engine speed. The pair reduces the crankshaft speed by about 4 times, that is, if the engine crankshaft rotates at a speed of 8 thousand rpm, then the rear wheels will rotate at a speed of 2 thousand rpm. The gears in the planetary pair of the VAZ 2107 are helical. This solution was not chosen by chance: a helical gear is almost twice as quiet as a spur gear.

The planetary pair has a helical gear to reduce noise levels

But helical planetary pairs also have a disadvantage: the gears can move along their axes as they wear out. However, this problem is relevant for racing cars, the rear axles of which have exclusively spur gears. And for all the years of production of this car, the VAZ 2107 had exclusively helical planetary pairs.

Types of auto parts

According to their location, gearboxes are divided into:

Front axle (used in front-wheel drive cars).
Rear (used in rear-wheel drive vehicles).

Both versions of the spare part are installed in all-wheel drive vehicles.

There are four types of gearboxes:

Conical (suitable for vehicles with all-wheel or rear-wheel drive).
Cylindrical (used on cars with front-wheel drive).
Hypoid (installed in cars with all-wheel or rear-wheel drive).
Worm (used in the steering mechanism).

There are also gearboxes:

With a high gear ratio (mounted on the transmission of cars with a large curb weight).
With a low gear ratio (installed on car transmissions with low associated mass).

The gearbox on the VAZ 2107 can be:
