Solution

1. Preparation

Gather tools including a jack, jack stands, lug wrench, tire pressure gauge, and alignment tools.
Ensure the vehicle is parked on a flat surface and turn off the engine.

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure in all tires.
- Inflate or deflate tires to the recommended PSI found in the owner’s manual.
Visual Inspection:
- Inspect each tire for signs of damage such as bulges, cracks, or uneven wear.
- Replace any damaged tires as necessary.

3. Wheel Balancing

Remove Wheels:
- Loosen lug nuts with a lug wrench, then lift the vehicle using a jack and secure with jack stands.
- Completely remove the wheels from the hubs.
Balance Wheels:
- Use a wheel balancer to check the balance of each wheel and tire combination.
- Add wheel weights as needed to achieve proper balance.

4. Wheel Alignment

Adjust Alignment:
- If misalignment is suspected, use an alignment machine to measure camber, toe, and caster angles.
- Adjust components according to manufacturer specifications to correct alignment.

5. Suspension Inspection

Examine Suspension:
- Inspect all suspension components for wear, including control arms, bushings, and struts.
- Replace any worn or damaged parts as necessary.

6. Reassemble and Lower Vehicle

Reattach Wheels:
- Place wheels back onto the hubs and hand-tighten lug nuts.
- Lower the vehicle and use a torque wrench to tighten lug nuts to the manufacturer’s specification (typically 80-100 ft-lbs).
