Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on any electrical components.

2. Adjust Tire Pressure

Use a tire pressure gauge to measure the air pressure in each tire.
Inflate or deflate tires as necessary to meet the recommended pressure found in the driver's door jamb sticker.

3. Tire Rotation and Inspection

Remove the front tires using a socket set.
Inspect tread depth with a tread depth gauge.
Rotate tires if uneven wear is detected, moving the rear tires to the front and vice versa.
Reinstall the tires and torque the lug nuts to the manufacturer’s specifications.

4. Wheel Alignment

Set up the vehicle on a wheel alignment rack.
Adjust the alignment angles (caster, camber, toe) according to the manufacturer’s specifications.
Perform a test drive to confirm that the pull has been corrected.

5. Suspension Inspection and Repair

Inspect control arms, tie rods, and struts for signs of wear or damage.
Replace any worn or damaged components as necessary.
Recheck alignment after any suspension repairs.
