Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure of all tires.
2. Inflate or deflate tires to match the recommended pressure found on the driver's door jamb.

3. Wheel Alignment

Sub-steps:
1. Raise the front end of the vehicle using a jack and secure it on jack stands.
2. Remove the front tires.
3. Use a wheel alignment tool to measure camber, caster, and toe angles.
4. Adjust the alignment as necessary using adjustment bolts on the suspension.
5. Reinstall the front tires and lower the vehicle.

4. Suspension Component Inspection and Replacement

Sub-steps:
1. Inspect ball joints and bushings for wear and replace them if they are damaged.
2. Check shocks/struts for leakage or damage and replace if necessary.
3. Tighten all suspension bolts to manufacturer specifications.

5. Tire Rotation

Sub-steps:
1. Rotate the tires according to the manufacturer's recommended pattern.
2. Use a torque wrench to tighten lug nuts to the specified torque (usually around 100-150 lb-ft, check the owner’s manual for specifics).

6. Final Inspection

Sub-steps:
1. Check for any remaining signs of uneven wear once repairs are complete.
2. Test drive the vehicle to ensure there are no pulling or vibrations.
