Solution

1. Tire Inspection and Rotation

Sub-steps:
- Inspect all tires for bulges, cuts, or uneven wear.
- Rotate tires if uneven wear is found to promote even wear patterns.
- Inflate tires to the manufacturer's recommended pressure.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Take the wheels to a tire shop or use a wheel balancer to check for imbalances.
- Add weights as necessary to balance each wheel.
- Reinstall the wheels and torque to the manufacturer's specifications (usually around 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
- After balancing, take the vehicle to an alignment shop.
- Perform a four-wheel alignment to adjust camber, caster, and toe settings.
- Ensure all specifications are within manufacturer tolerances.

4. Suspension Inspection and Repair

Sub-steps:
- Visually inspect all suspension components for wear or damage.
- Replace any worn or damaged components (e.g., bushings, struts) as necessary.
- Ensure all bolts and fasteners are tightened to the specified torque values.

5. Drivetrain Inspection

Sub-steps:
- Inspect CV joints and driveshaft for any play or damage.
- Replace any faulty components as identified during inspection.
- Ensure all connections are secure and intact.
