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

The first indication of failure is often a clunking sound when shifting between forward and reverse or during acceleration. This can progress to severe vibration felt throughout the machine's chassis. A complete failure can result in a loss of drive power and potential damage to the driveshaft and transmission.

Installation Tip

Before installing, ensure the mating surfaces of the driveshafts are clean and free of burrs that could interfere with proper seating. Do not overtighten the U-joint cap bolts, as this can distort the bearing caps and lead to premature failure.

Service Note

When replacing the universal joint, inspect the driveshaft yokes and companion flanges for wear or cracks.
