Solution

1. Preparation

Tools Required: Tire pressure gauge, floor jack, jack stands, torque wrench, alignment machine
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Gather all necessary tools and parts for the repair.

2. Check and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires as needed to match the recommended pressures found in the owner’s manual or on the driver’s side door jamb sticker.

3. Inspect Tires

Remove the wheels for easier inspection if necessary.
Check for uneven wear patterns; if found, consider rotating tires or replacing them if they are significantly worn.
Ensure all tires are balanced properly. If not, have them balanced at a tire shop.

4. Inspect and Repair Suspension Components

Visually inspect all suspension components for wear or damage. Pay close attention to control arms, bushings, and ball joints.
Replace any damaged or worn components with OEM parts. Follow torque specifications when reassembling.

5. Perform Wheel Alignment

Use an alignment machine to measure the alignment angles.
Adjust the camber, caster, and toe settings to the manufacturer's specifications.
Confirm that all adjustments have been made accurately and test drive the vehicle to ensure the pulling has been resolved.
