Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, alignment tool, wrench set, and torque wrench.
Park the vehicle on a flat surface and engage the parking brake.

2. Tire Inspection and Adjustment

Check Tire Pressure: Use a tire pressure gauge to check all tires. Inflate to the recommended PSI indicated on the door jamb sticker.
Inspect Tires: Look for uneven wear (cupping, bald spots) and check for any visible damage (cuts, bubbles).

Set Up Alignment Equipment: Position the alignment rack according to the manufacturer's specifications.
Adjust Alignment: Follow the alignment machine instructions to adjust the camber, caster, and toe settings to match the manufacturer's specifications.

4. Suspension and Steering Inspection

Inspect Suspension Components: Visually check for worn or damaged parts such as control arms, ball joints, and tie rods.
- Replace any damaged components as needed.
Check Steering Rack: Inspect for any play or excess movement in the steering rack and replace if necessary.

5. Reassemble and Test Drive

Reassemble Components: If any suspension or steering components were removed, reinstall them securely.
Torque Lug Nuts: Ensure all lug nuts are tightened to the manufacturer's specified torque (usually around 80-100 ft-lbs).
