Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Use a tire pressure gauge to check the tire pressure; ensure it matches the manufacturer's specifications.
2. Inspect all four tires for uneven wear; replace any tires that are excessively worn or damaged.
3. Rotate tires if uneven wear is detected to promote even wear.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Mount the wheels on a tire balancing machine.
3. Add weights to the wheels as indicated by the balancing machine to achieve balance.
4. Reinstall the wheels and torque the lug nuts to the specified torque (usually around 76-85 ft-lbs).

3. Suspension Component Replacement

Sub-steps:
1. Inspect the shocks and struts for leaks or damage.
2. If damaged, remove the old shocks/struts using a socket set and replace with new units.
3. Replace any worn bushings or mounts as necessary.
4. Reassemble and ensure all fasteners are torqued to the manufacturer’s specifications.

4. Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Use an alignment machine to check and adjust toe, camber, and caster angles as necessary.
3. Ensure that alignment settings are within manufacturer specifications.
