Solution

1. Tire Balance

Sub-steps:
1. Remove the wheel and tire from the vehicle using a lug wrench.
2. Mount the tire on a tire balancing machine.
3. Add or adjust wheel weights until the tire is balanced according to the machine's readings.
4. Reinstall the tire back onto the vehicle, tightening the lug nuts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).

2. Tire Inspection and Replacement

Sub-steps:
1. Visually inspect each tire for signs of damage (cracks, bulges, or punctures).
2. Check tread depth using a tread depth gauge, ensuring it meets safety standards (at least 2/32 inches).
3. If tires are damaged or worn excessively, replace them with new tires of the same specifications.

3. Wheel Alignment

Sub-steps:
1. Drive the vehicle to a professional alignment shop.
2. Follow the shop's procedures for performing a four-wheel alignment.
3. Adjust camber, caster, and toe settings as necessary to manufacturer specifications.

4. Suspension Inspection

Sub-steps:
1. Lift the vehicle securely using a jack and jack stands.
2. Inspect all suspension components for signs of wear (bushings, ball joints, shock absorbers).
3. Replace any worn or damaged components with OEM or quality aftermarket parts.

5. Test Drive

Sub-steps:
1. After performing repairs, conduct a test drive on a smooth highway.
2. Monitor for any vibrations or instability at high speeds.
3. Ensure the vehicle handles properly without pulling to one side.
