Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Tire Inspection and Replacement

Sub-steps:
- Remove wheel covers if present.
- Loosen lug nuts slightly while the vehicle is still on the ground.
- Jack up the vehicle and secure it with jack stands.
- Remove the wheels and inspect for damage or uneven wear.
- Replace any damaged tires with new ones, ensuring they are of the correct size and type.

3. Wheel Balancing

Sub-steps:
- Mount the wheels on a balancing machine.
- Follow the machine's instructions to balance each wheel and tire assembly.
- Add weights as needed to achieve proper balance.
- Reinstall the wheels on the vehicle and torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Align the vehicle using an alignment rack following the manufacturer’s specifications (typically, front caster, camber, and toe adjustments).
- Adjust the tie rods as necessary to achieve proper alignment angles.
- Test drive the vehicle again to ensure the alignment is correct.

5. Suspension Inspection and Repair

Sub-steps:
- Inspect struts and shocks for leaks or wear; replace if necessary.
- Check bushings, control arms, and tie rods for damage or excessive play; replace worn components.
- Reassemble any disassembled components, ensuring proper torque specifications.
