Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Inspect and Replace Tires

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels and inspect for uneven wear or damage.
- Replace any damaged tires with new ones, ensuring they are the correct size and type for the vehicle.
- Reinstall the wheels and torque to the manufacturer's specifications (usually around 80-100 ft-lbs).

3. Examine and Replace Wheel Bearings

Sub-steps:
- Remove the wheel and brake components to access the wheel bearing.
- Inspect the wheel bearing for any signs of wear or damage (e.g., roughness or excessive play).
- If necessary, replace the wheel bearing with a new unit, ensuring proper alignment and lubrication.
- Reassemble the wheel and brake components, tightening bolts to manufacturer's specifications.

4. Assess and Replace Brake Components

Sub-steps:
- Remove the wheel and inspect brake pads and rotors for wear.
- Measure the thickness of brake pads; replace if below the minimum specification (usually around 3mm).
- If rotors are warped or worn beyond specifications, replace them as well.
- Reassemble the brake components and ensure proper operation before reinstalling the wheel.
