Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools: jack, jack stands, tire pressure gauge, torque wrench, and wheel balancer.
Wear safety gloves and goggles.

2. Tire Inspection and Pressure Adjustment

Inspect Tires:
- Visually check each tire for damage, bulges, or uneven wear.
Adjust Tire Pressure:
- Use a tire pressure gauge to measure pressure.
- Inflate or deflate tires to meet the manufacturer's specifications.

3. Wheel Balancing

Remove Wheels:
- Loosen lug nuts, raise the vehicle with a jack, and secure with jack stands.
- Remove the wheels using a socket set.
Balance Wheels:
- Place each wheel on a wheel balancer and adjust weights accordingly.
- Reinstall each wheel and torque lug nuts to specifications (usually around 80-100 lb-ft).

4. Wheel Alignment

Perform Alignment:
- Using an alignment machine, adjust camber, caster, and toe to manufacturer specifications.
- Ensure all adjustments are made according to the vehicle's service manual.

5. Suspension Inspection

Inspect Components:
- Visually check shocks, struts, and control arms for signs of wear or damage.
- Replace any worn or damaged components as necessary.

6. Drivetrain Check

Inspect Driveshaft and CV Joints:
- Check for play or damage in the driveshaft and CV joints.
- Replace any faulty components.
