- Inspect the steering rack and tie rods for wear. If damaged, replace as necessary.
- Check the control arms and bushings; replace any worn components.
Wheel Bearings:
- Remove the wheel assembly by loosening the lug nuts and taking off the wheel.
- Inspect the wheel bearing by spinning it and listening for grinding noises.
- If the bearing is damaged, remove the hub assembly and replace the wheel bearing using a bearing press.

4. Reassemble and Refill

Reinstall any replaced components and torque to manufacturer specifications.
Refill the power steering fluid reservoir if it was drained during inspection.
Reconnect the battery.
