Solution

1. Tire Inspection and Rotation

Sub-steps:
- Use a tire pressure gauge to check and adjust tire pressures to manufacturer specifications.
- Inspect tires for uneven wear patterns; replace if necessary.
- Rotate tires if uneven wear is detected or at regular maintenance intervals.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a tire balancing machine.
- Add weights to the rim as indicated by the machine to balance the wheels.
- Reinstall the wheels and torque the lug nuts to the specified torque value (typically 100-150 ft-lbs depending on the model).

3. Suspension Inspection

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Visually inspect suspension components for signs of wear or damage (e.g., cracked bushings or worn ball joints).
- Replace any worn or damaged components.

4. Driveshaft and Universal Joint Inspection

Sub-steps:
- Inspect the driveshaft for any signs of damage or excessive play.
- Check universal joints for wear or binding; replace if necessary.
- Ensure all fasteners are tightened to the manufacturer's specifications.

5. Wheel Alignment

Sub-steps:
- Use an alignment machine to check the alignment settings.
- Adjust the alignment as necessary to bring it within manufacturer specifications.
