  • - monitor the oil level in the rear axle;
  • - clean the breather after driving through mud;
  • - perform maintenance on time.
  • - Cause of malfunction


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

- 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
