Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather safety equipment such as gloves and safety glasses.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check the tire pressure for each tire and inflate or deflate to the manufacturer's recommended PSI as indicated on the driver’s door jamb.

3. Tire Inspection and Replacement (if necessary)

Remove each wheel by loosening the lug nuts with a socket set, then lift the vehicle using a jack and secure it with jack stands.
Inspect each tire for damage or excessive wear. If any tire is found to be damaged or worn beyond the tread wear indicators, replace it with a new tire.
Parts Required: New tires (if applicable)

4. Wheel Balancing

Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically around 100-120 ft-lbs).
Use a wheel balancer to balance each wheel. Attach weights as necessary to correct any imbalances.

5. Wheel Alignment

After balancing, perform a wheel alignment using alignment equipment to ensure all wheels are set to the manufacturer’s specifications.
Adjust camber, toe, and caster angles as needed.

6. Suspension Inspection and Repair (if necessary)

Inspect suspension components for wear. If any parts, such as bushings or shocks, are worn or damaged, replace them accordingly.
Parts Required: Replacement suspension components (if applicable)
