Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, level surface.
Raise the vehicle using a jack and secure with jack stands.

2. Inspect and Replace Tires (if necessary)

Remove the wheels using a socket set.
Inspect the tire tread depth and wear patterns.
Replace any tires that are excessively worn or damaged.
Reinstall wheels and torque lug nuts to manufacturer specifications (usually 70-100 ft-lbs).

3. Adjust Wheel Alignment

Set up the vehicle on an alignment rack.
Adjust the camber, caster, and toe angles to the manufacturer's specifications.
Tighten all adjustment bolts to proper torque values.

4. Inspect and Replace Suspension Components (if necessary)

Check all suspension components (control arms, bushings, struts, shocks) for signs of wear or damage.
Replace any worn components using appropriate tools (e.g., a socket set, torque wrench).
Make sure to torque new components to manufacturer specifications.

5. Final Checks

Reinstall wheels if removed.
Lower the vehicle to the ground.
Check tire pressure one last time and adjust if necessary.
