Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment, including gloves and goggles.

2. Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to meet the manufacturer-recommended pressure (found on the driver’s door jamb label).

3. Inspect and Replace Tires (if necessary)

Remove the wheel covers or hubcaps (if applicable).
Use a lug wrench to loosen and remove lug nuts.
Inspect tires for damage; replace if tread is excessively worn or damaged.
Install new or reconditioned tires, ensuring proper rotation if applicable, and torque lug nuts to manufacturer specifications (usually 60-80 ft-lbs).

4. Perform Wheel Alignment

Drive the vehicle onto a wheel alignment rack.
Follow the specific manufacturer's procedure to adjust toe, camber, and caster angles to within specification using alignment tools.
Ensure all adjustments are locked in and recheck alignment settings.

5. Inspect and Repair Suspension/Steering Components

Check tie rods, ball joints, and control arms for wear or damage.
Replace any worn or damaged components as needed.
Torque new components to the manufacturer’s specifications.
