Solution

1. Preparation

Gather tools: socket set, jack stands, torque wrench, and a brake cleaner.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Brake System Inspection

Sub-steps:
1. Loosen the lug nuts on the affected wheel and lift the vehicle using a jack.
2. Remove the wheel to access the brake components.
3. Inspect the brake pads for thickness; replace if less than 3mm.
4. Check the brake rotors for scoring or uneven wear; replace if necessary.
5. Reinstall the wheel and torque lug nuts to manufacturer specifications.

3. Wheel Bearing Examination

Sub-steps:
1. With the wheel removed, grasp the wheel hub and try to wiggle it; any play indicates a bad wheel bearing.
2. If needed, replace the wheel bearing by removing the hub and pressing in a new bearing.
3. Reassemble the hub and wheel, ensuring proper torque on all fasteners.

4. Drivetrain Component Inspection

Sub-steps:
1. Inspect the drive axles for any visible damage or leaks.
2. Check the differential fluid level; add fluid if low.
3. Replace any worn or damaged seals and ensure all fasteners are tight.

5. Suspension Check

Sub-steps:
1. Inspect the suspension components (control arms, bushings) for wear or damage.
2. Replace any damaged parts as necessary.
3. Reassemble and ensure all bolts are properly torqued.
