Solution

1. Tire Inspection and Maintenance

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Check tire pressure using a tire pressure gauge and inflate to manufacturer specifications.
- Inspect tread depth using a tread depth gauge; replace tires if tread is below legal limits.
- Look for bulges, cracks, or uneven wear on the tire surface; replace damaged tires.

2. Wheel Balancing

Sub-steps:
- Remove the wheel from the axle using a lug wrench.
- Mount the wheel on a tire balancing machine.
- Follow the machine’s instructions to add the necessary weights to balance the wheel.
- Reinstall the wheel onto the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 100-150 ft-lbs depending on the model).

3. Wheel Alignment

Sub-steps:
- Drive the vehicle onto an alignment rack.
- Adjust the camber, caster, and toe according to the manufacturer’s specifications using alignment tools.
- Confirm alignment adjustments with the machine reading.
- Test drive the vehicle to ensure the steering wheel is centered and vibrations are resolved.

4. Suspension Inspection and Repair

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect all suspension components visually for signs of wear or damage (e.g., bushings, struts).
- Replace any worn or damaged components as needed.
- Reassemble any removed parts and lower the vehicle.

5. Driveshaft Inspection

Sub-steps:
- Check the driveshaft for any visible signs of damage or imbalance.
- Inspect U-joints for wear or play; replace if necessary.
- Ensure that all bolts are properly torqued to manufacturer specifications.
