Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to check the PSI of each tire.
Inflate or deflate tires to achieve the recommended PSI as stated on the door jamb label.

3. Wheel Balancing

Remove each wheel using a socket set and jack.
Place the wheel on a balancing machine.
Add weights to balance the wheel as indicated by the machine.
Reinstall the wheel and torque bolts to the manufacturer's specifications (usually around 100-120 lb-ft).

4. Wheel Alignment

Use a laser alignment tool to measure alignment angles.
Adjust camber, caster, and toe angles as necessary according to the manufacturer's specifications.
Recheck to ensure all angles are within the acceptable range.

5. Inspect Drivetrain Components

Inspect the driveshaft for any signs of damage or wear.
Check U-joints for play or corrosion and replace if needed.

6. Suspension Inspection

Visually inspect all suspension components for wear or damage.
Replace any worn or damaged parts such as ball joints, bushings, or control arms.
