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

Initial symptoms include a slight clunking sound when shifting into gear or changing direction. This can progress to persistent vibration, especially at higher speeds, and a noticeable looseness in the driveline. Failure can result in a complete loss of power to the drive wheels.

Installation Tip

Ensure the yoke ears on the shaft and the universal joint are perfectly aligned and clean before assembly. Never reuse old U-joint straps and bolts; always use new hardware to ensure a secure connection.

Service Note

Inspect the driveshaft, yokes, and associated mounting hardware for wear or damage when replacing this universal joint.
