Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a level surface and engage the parking brake.
Ensure the tires are cool to the touch.

2. Tire Inspection and Replacement

Inspect Tires
- Examine the tread depth and look for any signs of damage.
Replace Tires (if needed)
- Use a jack to lift the vehicle and remove the wheel using a socket set.
- Install new tires, ensuring proper alignment of the valve stem.
- Torque lug nuts to the manufacturer’s specifications (usually around 100-120 ft-lbs).

3. Wheel Balancing

Balance Wheels
- Mount the wheel on a balancing machine.
- Add balancing weights until the wheel is balanced according to the machine's specifications.
Reinstall Wheels
- Reattach the balanced wheel to the vehicle and torque the lug nuts.

4. Suspension and Steering Inspection

Inspect and Replace Suspension Components
- Visually inspect struts, control arms, and bushings for wear.
- Replace any worn components using appropriate tools (e.g., socket set, torque wrench).
- Follow manufacturer torque specifications during reassembly.
Steering Component Check
- Check tie rods and steering rack for play. Replace if necessary.

5. Wheel Alignment

Perform Alignment
- Use an alignment machine to adjust the camber, toe, and caster to manufacturer's specifications.
- Test drive the vehicle to ensure proper steering feel.
