Solution

1. Tire Check and Adjustment

Sub-steps:
- Measure the tire pressure using a tire gauge.
- Inflate or deflate tires to the recommended PSI as per the owner's manual.
- Check for tread depth using a tread depth gauge and replace tires if necessary.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a wheel balancing machine.
- Add weights as needed to balance the wheels correctly.
- Reinstall the wheels to the vehicle, ensuring proper torque specifications are followed (typically 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
- Place the vehicle on an alignment rack.
- Adjust the camber, caster, and toe according to manufacturer specifications.
- Test drive the vehicle to confirm proper alignment.

4. Suspension Inspection and Repair

Sub-steps:
- Visually inspect shock absorbers, struts, and bushings for wear.
- Replace any worn components with OEM or high-quality aftermarket parts.
- Reassemble and torque all suspension components to manufacturer specifications.

5. Driveshaft and Wheel Bearings Check

Sub-steps:
- Lift the vehicle and secure it with jack stands.
- Inspect the driveshaft for any signs of wear or damage.
- Check wheel bearings for play and replace if they feel loose or gritty.
