Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed.

2. Tire Inspection and Adjustment

Sub-steps:
- Check tire pressure with a tire gauge; adjust to manufacturer's specifications (typically found on the driver's door jamb).
- Inspect tire tread depth using a tread depth gauge; replace tires if tread is below 2/32".
- Rotate tires if uneven wear is detected, following the vehicle's recommended tire rotation pattern.

3. Suspension Inspection and Repair

Sub-steps:
- Visually inspect suspension components for damage or wear. Replace any faulty parts, such as worn shocks or struts.
- Tighten any loose suspension bolts to the manufacturer’s torque specifications.
- If necessary, replace suspension bushings that show signs of cracking or deterioration.

4. Wheel Alignment

Sub-steps:
- Take the vehicle to an alignment shop.
- Perform a four-wheel alignment to ensure all wheels are positioned correctly.
- Adjust camber, caster, and toe angles as per manufacturer specifications.

5. Steering System Check

Sub-steps:
- Inspect tie rods for any play or damage; replace if necessary.
- Check the steering rack for leaks or play; repair or replace as needed.
- Lubricate any accessible points in the steering system.

6. Wheel Balancing

Sub-steps:
- Remove the wheels and tires from the vehicle.
- Mount the tires on a wheel balancer to check for balance.
- Add balancing weights to the rim as needed to achieve proper balance.
