Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, and OBD-II scanner.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery if performing electrical work.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using the lug wrench.
2. Inspect brake pads for thickness; replace if below manufacturer's specification (typically 3mm).
3. Check brake rotors for scoring or warping; replace if necessary.
4. Reassemble the brake components and wheel, torque lug nuts to manufacturer specifications (usually about 80-100 ft-lbs).

3. Check and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Support the vehicle on jack stands, remove the wheel.
2. Spin the hub assembly by hand; listen for grinding noise indicating bearing failure.
3. If noise is present, remove the hub assembly and replace the wheel bearing.
4. Reassemble the hub and wheel, torquing to specifications.

4. Inspect Drive Train Components

Sub-steps:
1. Inspect CV joints for tears or grease leakage; replace if damaged.
2. Check axles for bending or damage; replace if necessary.
3. Reassemble all components ensuring proper alignment and fastening.
