Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Check tire tread depth and look for any bulges or irregularities.
2. Inflate tires to the manufacturer-recommended pressure.
3. If tires are worn or damaged, replace with new tires that meet specifications.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Mount the wheels on a wheel balancing machine.
3. Adjust weights as necessary to achieve proper balance.
4. Reinstall the wheels, tightening lug nuts to the manufacturer's torque specifications (typically around 100-120 ft-lbs).

3. Suspension Component Inspection and Repair

Sub-steps:
1. Inspect all suspension components (e.g., control arms, bushings, struts) for damage or wear.
2. Replace any worn or damaged components with OEM parts.
3. After repairs, perform a wheel alignment to ensure proper handling and tire longevity.

4. Drivetrain Inspection and Repair

Sub-steps:
1. Inspect the driveshaft for any signs of damage or abnormal wear.
2. Check CV joints for play or wear; replace if necessary.
3. Ensure all drivetrain mounts are secure and in good condition.
