Solution

1. Tire Inspection and Replacement

Sub-steps:
- Check all tires for uneven wear, bulges, or damage.
- Measure tire pressure and adjust to recommended levels.
- If tires are worn out, replace them with new ones of the same specification.
Tools Required: Tire pressure gauge, jack, tire iron

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a jack and tire iron.
- Mount the wheels on a wheel balancer and spin to check for imbalances.
- Add weights as necessary to achieve proper balance.
- Reinstall the wheels and torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).
Tools Required: Wheel balancer, jack, torque wrench

3. Wheel Alignment

Sub-steps:
- Use an alignment machine to measure the current alignment angles.
- Adjust the camber, caster, and toe as needed to match manufacturer specifications.
- Test the alignment after adjustments to ensure it is within tolerance.
Tools Required: Wheel alignment machine

4. Suspension Inspection and Repair

Sub-steps:
- Inspect shocks, struts, and bushings for wear or damage.
- Replace any worn components with OEM or high-quality aftermarket parts.
- Ensure all bolts are properly torqued and that the suspension geometry is correct.
Tools Required: Socket set, torque wrench, pry bar

5. Driveshaft Inspection

Sub-steps:
- Inspect the driveshaft for any visible damage or rust.
- Check U-joints for play by twisting and pulling them; replace if necessary.
- Ensure that all connections are tight and properly lubricated.
Tools Required: Socket set, pry bar, lubricant
