The car is equipped with a rear axle with a stamped-welded banjo-type crankcase with a separately mounted gearbox

The main gear and the rear axle differential are installed in the gearbox housing 8, which is bolted into the axle beam holes.

The main gear of the bridge is hypoid, with a gear ratio of 5.125; the axis of the drive gear relative to the driven gear is shifted down by 42 mm.

The preload of the drive gear bearings is adjusted by selecting ring 5, and the position of the drive gear is adjusted by selecting ring 7.

The side clearance in the main gear engagement is adjusted by nuts 16.

The same nuts adjust the differential bearing preload.

The locking of the nuts is made by the locking plate 14.

The pinion gears and side gears are located in the differential housing, which consists of left and right boxes bolted together.

To prevent pressure build-up inside the axle, a breather is mounted on top of the left axle housing.

Possible malfunctions of the rear axle. Their causes and remedies

- Cause of malfunction


The noise (hum) of the high-volume bridge:

- Loosening the pinion flange nut

Tighten the nut

- Wear or play of the working surfaces of the bearings of the drive gear or differential

Check the running surfaces of the bearings and, if necessary, replace them. Adjust bearing preload

Ripple bridge noise (binding)

- Loosening of the fastening bolts of the driven gear or it is installed skewed

Tighten the bolts of the driven gear and check the runout of its "nape"

High tone bridge "howl" noise:

- Insufficient or excessive oil level

Restore oil level to normal

- Non-recommended oil used

Change the oil

- Incorrectly adjusted contact between the teeth of the new final drive gears

Check the contact patch and adjust it

- Seizures on the working surface of the main gear teeth

Replace gears

Strong knocking in the axle when the accelerator pedal is pressed hard after coasting or cornering:

- Excessive wear of differential parts

Check total play in final drive and differential

Replace worn parts

Continuous thumping and crunching in the bridge:

- Wear of teeth or bearings

Replace worn parts

Oil leak through the cuffs of the drive gear, the hub, as well as along the plane of the crankcase connector and the cover:

- Wear of the cuffs of the drive gear and the hubs of the rear wheels, the flange of the drive gear, the crankcase trunnion

Replace worn parts

- Clogged breather

Clean breather

- Loosening the crankcase cover bolts

Tighten the bolts

  • - Crankcase cover deformation
  • - Lid gasket damage

Replace cover

Replace gasket


Cars produced in 2007 and 2008 the stocking of the rear axle was released with a defect, there were a lot of cases of stocking rupture in the area of ​​u200bu200bfastening the hub.

Be careful when operating cars of this year of manufacture. Do not overload the rear axle. There were cases of breakage along with the axle shaft.
