Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.

2. Tire Inspection and Maintenance

Sub-steps:
1. Remove the wheel covers if applicable.
2. Inspect each tire for damage and uneven wear.
3. Use a tire pressure gauge to check and adjust each tire to the recommended PSI.
4. Rotate the tires if uneven wear is present.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Take the wheels to a tire shop or use a wheel balancing machine.
3. Add weights to balance the wheels as needed.
4. Reinstall the wheels, ensuring proper torque specifications (usually 80-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
1. Use an alignment tool or take the vehicle to a professional alignment shop.
2. Adjust camber, caster, and toe angles according to manufacturer specifications.
3. Test drive the vehicle to ensure the alignment is correct.

5. Suspension and Driveline Inspection

Sub-steps:
1. Visually inspect suspension components for wear or damage.
2. Check CV joints for any tears or leaks.
3. Ensure all bolts and fasteners are secured to specified torque values.
4. Replace any worn or damaged components as necessary.
