1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface.
Use wheel chocks to prevent the vehicle from rolling.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers if applicable.
2. Check each tire's tread depth and condition.
3. If tires are worn or damaged, replace them with OEM or high-quality alternatives.
4. Inflate new or existing tires to the manufacturer-recommended pressure.

3. Wheel Balancing

Tools Required: Wheel balancer
Sub-steps:
1. Remove the wheels from the vehicle.
2. Mount each wheel on the wheel balancer.
3. Follow the balancer's instructions to adjust weights as needed.
4. Reinstall the balanced wheels onto the vehicle.

4. Suspension Component Inspection and Repair

Tools Required: Jack and jack stands, socket set, torque wrench
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect shock absorbers, struts, control arms, and bushings for signs of wear or damage.
3. Replace any worn or damaged components.
4. Torque all fasteners to the manufacturer's specifications.

5. Driveshaft and Axle Inspection

Tools Required: Socket set, torque wrench
Sub-steps:
1. Inspect the driveshaft for any signs of bending or damage.
