Solution

1. Preparation

Tools Required: Wheel alignment machine, torque wrench, tire pressure gauge
Ensure the vehicle is on a level surface and securely lifted using ramps or a jack and jack stands.

2. Adjust Tire Pressure

Check the tire pressure using a tire pressure gauge.
Inflate or deflate tires as necessary to meet the recommended pressure listed on the door jamb or in the owner’s manual.

3. Inspect and Replace Tires (if necessary)

If uneven wear is observed, assess if the tires need to be rotated or replaced.
If replacement is needed, remove the tires using a socket set and replace them with new, properly balanced tires.

4. Perform Wheel Alignment

Position the vehicle on the alignment machine.
Adjust the alignment angles (camber, caster, toe) according to the manufacturer’s specifications.
Tighten all fasteners to the specified torque values using a torque wrench.

5. Recheck Steering and Test Drive

Once alignment is complete, test drive the vehicle to ensure straight tracking and that the steering wheel is centered.
Make any necessary adjustments if the steering behavior is still not satisfactory.
