The vehicle can be equipped with a solid beam axle or a rear banjo 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 driving through mud;
- - perform maintenance on time.
- - Cause of malfunction
Remedy
Noise (hum) of the bridge at high volume:
- Loosening the drive gear flange nut
Tighten the nut
- Wear or play of the working surfaces of the drive gear or differential bearings
Check the running surfaces of the bearings and, if necessary, replace them. Adjust the bearing tension, article - "Assembling and adjusting the axle gearbox"
Bridge pulsating noise (winding up)
- The driven gear fastening bolts are loose or it is installed askew
Tighten the driven gear mounting bolts and check the runout of its “back”
High pitch bridge "howl" noise:
- Insufficient or excessive oil level
Restore the oil level to normal, article - "How to change the oil in the rear axle gearbox"
- Non-recommended oil is used
Change oil
- The contact between the teeth of the new final drive gears is incorrectly adjusted
Check the contact patch and adjust it
- Scoring on the working surface of the main gear teeth
Replace gears
A strong knocking sound in the axle when you sharply press the accelerator pedal after coasting or when turning:
- Excessive wear of differential parts
Check the total play in the main gear and differential
Replace worn parts
Continuous knocking and crunching in the bridge:
- Wear of teeth or bearings
Replace worn parts
Oil leakage through the cuffs of the drive gear, hub, as well as along the plane of the crankcase and cover connector:
- Wear of drive gear cuffs and rear wheel hubs, drive gear flange, crankcase axle
Replace worn parts
- Breather clogged
Clean the breather
- Loosening the crankcase cover bolts
Tighten the bolts
- - Deformation of the crankcase cover
- - Damage to the cover gasket
Replace the cover
Replace gasket
