Solution

1. Tire Inspection

Sub-steps:
1. Inspect each tire for visible damage.
2. Measure tire tread depth; replace tires if tread is below 2/32 of an inch.
3. Ensure all tires are inflated to the recommended pressure (usually found on a sticker in the driver’s door jamb).

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Take wheels to a tire shop for balancing.
3. Reinstall wheels, ensuring to torque lug nuts to manufacturer specifications (typically 100-110 ft-lbs).

3. Suspension Inspection

Sub-steps:
1. Visually inspect suspension components (shocks, struts, control arms) for signs of wear.
2. Replace any worn or damaged suspension parts.
3. If replacements are made, ensure to align the suspension.

4. Wheel Alignment

Sub-steps:
1. After all repairs, take the vehicle to an alignment shop.
2. Adjust toe, camber, and caster angles to factory specifications.
3. Test drive to confirm the stability of the vehicle at high speeds.
