Replace the CV joint or axle as necessary.
Reinstall the wheel and torque the axle nut to manufacturer specifications.

4. Inspect Wheel Bearings

Spin the wheel by hand; listen for grinding noises.
If noise is present, remove the wheel hub assembly.
Replace wheel bearings if they show signs of wear or damage.
Reassemble the hub and torque all components to specifications.

5. Check Suspension Components
