Sub-steps:
1. After removing the wheels, inspect the wheel bearings for play by shaking the wheel up and down.
2. If wear is detected, remove the brake caliper and rotor.
3. Remove the hub assembly and replace the wheel bearings using a bearing press.
4. Reassemble the hub assembly, rotor, and caliper, ensuring all bolts are torqued to specification.

4. Check Steering Rack and Linkage

Sub-steps:
1. Inspect the steering rack for any visible damage or leaks.
2. Check the tie rod ends for play or damage. Replace if necessary.
3. Ensure all mounting bolts for the steering rack are secure and torque to specification.
