Solution

1. Preparation

Gather tools and materials, including a floor jack, jack stands, tire pressure gauge, alignment machine, and a torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to the recommended pressure as specified in the owner’s manual.

3. Check and Rotate Tires

Remove the tires from the vehicle using a floor jack and jack stands.
Inspect each tire for uneven wear or damage. Rotate tires to ensure even wear.
Reinstall the tires and torque the lug nuts to the manufacturer’s specifications.

4. Inspect Steering and Suspension Components

Visually inspect the steering linkage and suspension components for any signs of wear or damage.
Replace any worn or damaged parts, such as tie rods or ball joints.

5. Perform Wheel Alignment

Set up the vehicle on an alignment rack and follow the manufacturer’s specifications to adjust the alignment angles (camber, caster, toe).
Adjust the settings until they meet manufacturer specifications.

6. Test Drive and Final Adjustments

Take the vehicle for a test drive to check if the pulling has been resolved.
If necessary, make further adjustments to the alignment based on test drive observations.
