Increased noise from the rear wheels
Cause of malfunction | Elimination Method |
1. Loose wheel fastening. | 1. Tighten the wheel nuts. |
2. Wear or destruction of the half shaft ball bearing. | 2. Inspect axle shaft and replace bearing. |
Constant increased noise during the operation of the rear axle
Cause of malfunction | Elimination Method |
1. The rear axle beam is deformed, the axle shaft bearings are damaged. | 1. Straighten the beam and check its dimensions, replace the axle shaft bearings. |
2. The axle shafts are deformed and have unacceptable runout. | 2. Straighten the axle shafts. If they are significantly damaged, replace them with new ones. |
3. Incorrect adjustment, damage or wear of gears or gearbox bearings. | 3. Determine the fault and repair the gearbox. |
4. Worn or incorrectly adjusted differential bearings. | 4. Remove gearbox, repair and adjust. |
Noise during acceleration and engine braking
Cause of malfunction | Elimination Method |
1. Incorrectly adjusted the gear teeth of the main gear when repairing the gearbox. | 1. Adjust gear engagement. |
2. Damage to axle bearings. | 2. Replace bearings. |
3. Not enough oil. | 3. Restore the oil level and check for leakage in the seals or in the rear axle beam. |
4. Incorrect clearance in engagement between final drive gears. | 4. Adjust the gap. |
5. Increased clearance in pinion bearings due to loose flange nut or worn bearings. | 5. Check the moment of resistance to rotation of the drive gear, tighten the nut or replace damaged parts. |
Noise when cornering
Cause of malfunction | Elimination Method |
1. Damage to axle bearings. | 1. Replace bearings. |
Knocking at start up
Cause of malfunction | Elimination Method |
1. Wear of the hole for the axis of the satellites in the differential box. | 1. Replace differential box. |
2. Loose rear suspension rod bolts. | 2. Tighten the bolts. |
Oil leak
Cause of malfunction | Elimination Method |
1. Worn or damaged drive gear oil seal. | 1. Replace the oil seal. |
2. Wear of the axle shaft seal, determined by the oiling of the brake shields, drums and shoes. | 2. Check the runout of the axle shaft, deflection of the beam. Straighten or replace damaged parts. |
3. Loosening of the mounting bolts of the rear axle gearbox housing, damage to the seals. | 3. Tighten bolts, replace gaskets. |
