Solution

1. Preparation

Gather tools: tire pressure gauge, jack, jack stands, lug wrench, OBD-II scanner.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Tire Inspection and Balancing

Check Tire Pressure
- Use a tire pressure gauge to measure tire pressure.
- Inflate tires to the correct PSI as indicated on the driver's door jamb.
Inspect Tires for Damage
- Visually inspect each tire for bulges, cuts, or uneven wear patterns.
- Replace any damaged tires as necessary.
Wheel Balancing
- Remove the wheel and tire assembly using a lug wrench.
- Take the wheel to a tire shop or use a wheel balancer to check for balance.
- Adjust weights as needed to balance the wheel.
- Reinstall the wheel and torque lug nuts to manufacturer specifications (usually around 80-90 ft-lbs).

3. Suspension Inspection

Visual Inspection
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect suspension components for visible wear, including bushings, ball joints, and bearings.
Check for Play
- Grasp the wheel at the 12 and 6 o'clock positions and shake it to check for play, indicating worn components.
- Replace any worn or damaged suspension parts as required.

4. Test Drive

After making the necessary repairs, take the vehicle for a test drive.
Monitor for vibrations, ensuring they have been resolved.
