Failure Symptoms

The first symptom of a failing companion flange is often a noticeable clunking sound when engaging the drivetrain or changing gears. This can progress to significant vibration felt throughout the vehicle during operation. If left unaddressed, the connection can loosen further, potentially leading to driveshaft separation and loss of propulsion.

Installation Tip

Ensure the mating surfaces on both the driveshaft and the differential are clean and free of debris before installation. Do not overtighten the flange bolts, as this can strip threads or warp the flange.

Service Note

Inspect the universal joints and U-bolts for wear or damage, and check the condition of the differential pinion seal.
