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.
