Solution

1. Tire Balancing

Sub-steps:
1. Remove the wheel from the vehicle using a lug wrench.
2. Mount the wheel on a tire balancer.
3. Adjust weights as necessary until the wheel is balanced.
4. Reinstall the wheel and tighten lug nuts to the manufacturer’s torque specifications (typically 80-100 ft-lbs).

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the inflation of all tires.
2. Inflate or deflate tires to match the manufacturer’s recommended pressure (usually found on the driver’s side door jamb).
3. Replace valve caps after adjustment.

3. Tire Replacement (if needed)

Sub-steps:
1. If tires show significant wear or damage, remove the old tire using a tire machine.
2. Install new tires, ensuring they are properly seated on the rim.
3. Balance the new tires as described in the Tire Balancing section.

4. Wheel Alignment

Sub-steps:
1. Use an alignment machine to measure existing wheel angles.
2. Adjust the camber, caster, and toe settings according to manufacturer specifications.
3. Test drive to ensure alignment is within acceptable limits.

5. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components for play or damage.
2. Replace any worn bushings or ball joints as necessary.
3. Reassemble components and perform a test drive to verify repair.
