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

A common initial symptom is a distinct grinding or whining sound emanating from the final drive area. If left unaddressed, the bearing can seize, leading to a loss of drive power and potential damage to gears and shafts. Continued operation risks severe damage to the entire final drive assembly.

Installation Tip

Ensure the bearing bore and shaft are perfectly clean and free from any debris or burrs before installation. Never use heat to expand the bearing unless specifically instructed by the service manual, as this can alter its temper.

Service Note

Inspect the final drive gears, seals, and the drive shaft for wear or damage when replacing this bearing.
