Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- OBD-II scanner
- Brake cleaner
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if less than 3mm thickness.
3. Check rotors for scoring or warping; replace if necessary.
  - Parts Required: Brake pads, rotors (if needed).
4. Clean the brake assembly with brake cleaner to remove dust and debris.
5. Reinstall the wheel and torque bolts to the manufacturer's specifications.

3. Check Wheel Bearings

Sub-steps:
1. Lift the vehicle and securely support it with jack stands.
2. Grasp the wheel at the 12 and 6 o'clock positions and shake; if there's play, the bearing may be worn.
3. If needed, remove the wheel and hub assembly to access the bearing.
4. Replace the bearing if it is found to be defective.
  - Parts Required: Wheel bearings.
5. Reassemble the wheel and torque to specifications.

4. Examine Drivetrain Components

Sub-steps:
1. Inspect the drive axles for any visible damage or disconnection.
2. Check motor mounts for wear or cracking.
3. Tighten any loose connections and replace any damaged components.
  - Parts Required: Drive axles or motor mounts (if needed).
