Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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 a failing companion flange is often a clunking sound when engaging or disengaging power. If left unaddressed, this can progress to noticeable vibrations and potential loss of drive. A severely damaged flange can lead to driveshaft separation, posing a significant risk to equipment and personnel.

Installation Tip

Ensure the mating surfaces on both the driveshaft yoke and the differential pinion are clean and free of burrs before assembly. Avoid using excessive force when aligning the bolt holes, as this can indicate a misalignment issue.

Service Note

Inspect the universal joints (U-joints) and the differential pinion seal for wear or leaks when replacing the companion flange.
