Solution

1. Preparation

Gather tools: Socket set, torque wrench, jack stands, wheel chocks, and a wheel balancer.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection and Pressure Adjustment

Remove the hubcaps (if applicable) and check tire pressure with a tire gauge.
Inflate or deflate tires to manufacturer-recommended pressure.
Inspect each tire for signs of uneven wear or damage.

3. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Mount each wheel onto the wheel balancer and follow the machine's instructions for balancing.
Adjust weights as necessary to achieve proper balance.

4. Suspension Inspection

Inspect each suspension component for signs of wear or damage. Pay attention to the following:
- Tie rods: Look for looseness or play.
- Ball joints: Check for grease leakage or cracks in the rubber boot.
- Control arms: Inspect for rust or fractures.
Replace any worn or damaged components as necessary.

5. Wheel Alignment

After ensuring proper wheel balance, mount the wheels back onto the vehicle and torque to manufacturer specifications.
Use a laser alignment tool to check the alignment and adjust as necessary to meet manufacturer specifications.
