- Cause of malfunction
Remedy
Increased noise from rear wheels
- The wheel fastening is loose
Tighten the wheel nuts
- Wear or destruction of the half shaft ball bearing
Inspect axle shaft and replace bearing
Constant increased noise during operation of the rear axle
- The rear axle beam is deformed, the axle bearings are damaged
Straighten the beam and check its dimensions, replace the axle shaft bearings
- Half shafts are deformed and have unacceptable runout
Replace the axle shafts with new ones
- Incorrect adjustment, damage or wear of gears or gearbox bearings
Find gearbox failure, repair or replace gearbox
- Worn or incorrectly adjusted differential bearings
Remove gearbox, repair and adjust
Noise during car acceleration and engine braking
- Incorrect adjustment of the main gear engagement
Adjust the hook

Replace bearings
- Not enough oil
Replenish the oil level and check for leaks in the seals or in the rear axle beam
- Incorrect lateral clearance in the meshing of the final drive gears
Adjust the gap
- Increased clearance in the drive gear bearings due to loosening of the flange mounting nut or wear of the bearings
Adjust clearance, replace bearings if necessary
Noise when cornering
- Damage to axle bearings
Replace bearings
Knocking at the beginning of the car
- Wear of the hole for the axis of the satellites in the differential box
Replace the differential box and, if necessary, the pinion axle
- The bolts of the rear suspension rods have loosened
Tighten the bolts
Oil leak
- Wear or damage to the drive gear oil seal
Replace the oil seal
- Wear of the axle shaft seal, leading to oiling of the brake shields, drums and shoes
