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 signs of failure may include increased jolting over uneven surfaces or audible clunking sounds from the rear of the machine. If left unaddressed, the suspension's ability to absorb shock will degrade, leading to excessive wear on other drivetrain components. Continued operation with a compromised suspension can result in instability and potential damage to the chassis.

Installation Tip

Ensure all mounting surfaces are clean and free of debris before installation to guarantee a proper seal. Avoid overtightening fasteners, as this can damage the suspension components or mounting points.

Service Note

Inspect shock absorbers, trailing arms, and mounting hardware for wear or damage when replacing the rear suspension group.
