Solution

1. Preparation

Park the vehicle on a flat surface and ensure the engine is off.
Gather required tools.
Safety warning: Ensure the vehicle is in "Park" (automatic) or in gear (manual) with the parking brake engaged.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all four tires.
Inflate or deflate tires to the recommended pressure as stated on the driver's door jamb.
Recheck pressure after adjustments.

3. Tire Inspection and Rotation

Remove all four tires using a socket set.
Inspect each tire for uneven wear or damage (e.g., bulges, cuts).
Rotate the tires if needed (front to back and side to side) to promote even wear.

4. Wheel Alignment

Attach alignment tools to the vehicle’s wheels as per the manufacturer’s specifications.
Adjust the alignment settings (toe, camber, and caster) to factory specifications using the alignment machine.
Verify adjustments by ensuring the steering wheel is centered.

5. Suspension Check

Inspect suspension components, looking for worn or damaged parts such as struts, shocks, and bushings.
Replace any damaged parts using appropriate tools and torque them to manufacturer specifications.
