Failure Symptoms

The first symptom of a failing rear hub is often a humming or grinding noise that increases with vehicle speed. This can progress to noticeable looseness in the wheel, causing vibration and affecting steering stability. Continued operation risks bearing failure and potential wheel detachment.

Installation Tip

Thoroughly clean the mounting surface on the axle housing and the hub itself to ensure a flush fit and proper torque distribution. Avoid reusing old hub nuts or bolts, as they may be stretched or weakened.

Service Note

Inspect and replace wheel bearings and seals, and check brake components (rotors, pads, calipers) for wear when servicing the rear hub.
