Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, OBD-II scanner (for any related codes)
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electronic components.

2. Tire and Wheel Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect each tire for bulges, cracks, or foreign objects embedded in the tread.
3. Measure tire pressure and adjust if necessary.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels using a lug wrench.
2. Mount each wheel on a balancing machine and spin to detect imbalances.
3. Add balancing weights as necessary to achieve proper balance.
4. Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (generally 80-100 lb-ft).

4. Suspension Inspection

Sub-steps:
1. Visually inspect all suspension components for cracks, excessive wear, or play.
2. Replace any worn or damaged components (e.g., control arms, bushings, struts).
3. Ensure all bolts and nuts are tightened to the specified torque.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to an alignment shop.
2. Measure the alignment angles (camber, caster, toe).
3. Adjust the alignment to meet manufacturer specifications.
