Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Tire Inspection

Sub-steps:
- Check tire pressure using a tire gauge and inflate to the recommended PSI.
- Inspect tires for uneven wear patterns, bulges, or damage.
- Replace any damaged tires as needed.

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a tire balancer.
- Adjust weights as necessary to achieve balance.
- Reinstall the wheels and torque to the manufacturer’s specifications (typically around 80-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Take the vehicle to a professional alignment shop or use an alignment tool.
- Adjust the camber, caster, and toe settings according to manufacturer specifications.
- Test drive the vehicle to confirm proper alignment.

5. Suspension Inspection

Sub-steps:
- Visually inspect control arms, bushings, and tie rods for wear or damage.
- Replace any worn or damaged suspension components using appropriate tools.

6. Brake System Check

Sub-steps:
- Inspect brake rotors for warping using a dial indicator.
- Resurface or replace rotors if found to be warped.
- Reassemble brake components and ensure proper functioning.
