The vehicle can be fitted with a solid beam axle or a banjo rear axle
In order for the rear axle gearbox to last longer, you need:
- - do not overload the car;
- - monitor the oil level in the rear axle;
- - clean the breather after a trip through the mud;
- - perform maintenance on time.
- - Cause of failure
Remedy
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
Pulsating 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 bridge 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 leaks 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
