Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of a failing rear axle assembly include whining or clunking noises during operation, especially when turning. If ignored, these noises will worsen, and the equipment may exhibit poor handling, reduced power to the wheels, or oil leaks from the differential housing. Continued operation risks differential damage and loss of drive.

Installation Tip

Ensure all mounting bolts and drive shafts are properly aligned before tightening to prevent stress on the new assembly. Use the correct thread-locking compound where specified.

Service Note

Inspect the differential, drive shafts, and wheel bearings for wear or damage when replacing the rear axle assembly.
