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 indications of failure might include a subtle increase in road noise or a slight looseness in the wheel assembly. If neglected, the noise will become more pronounced, potentially accompanied by excessive heat and vibration, which can lead to wheel instability. Continued operation risks damage to the axle housing and potential wheel detachment.

Installation Tip

Thoroughly clean the bearing seat in the hub and the shaft where the bearing will be mounted to ensure a proper fit. Avoid hammering the bearing; use a hydraulic press or appropriate bearing driver to install it squarely onto the shaft or into the housing.

Service Note

Inspect the axle seals and brake components, including pads and rotors, for wear or damage when servicing this bearing.
