Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Safety warning: Disconnect the battery before working on any electrical components.

2. Tire Inspection and Adjustment

Check Tire Pressure
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate or deflate tires to match the manufacturer's recommended specifications.
Inspect Tire Condition
- Examine each tire for signs of uneven wear or damage.
- If tires are worn unevenly, consider rotating or replacing them.

3. Suspension and Steering Inspection

Visual Inspection
- Jack up the vehicle and secure it on jack stands.
- Inspect suspension components (struts, springs, control arms) for signs of wear or damage.
- Check steering components (tie rods, bushings) for looseness or damage.
Replace Any Damaged Components
- If any parts are found to be damaged, remove and replace them using appropriate tools.
- Torque new components to manufacturer specifications.

4. Wheel Alignment

Perform Wheel Alignment
- Use an alignment machine or take the vehicle to an alignment shop.
- Adjust camber, caster, and toe angles to meet manufacturer specifications.

5. Final Inspection

Recheck all components for tightness and safety.
Remove the vehicle from jack stands and lower it to the ground.
