Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed.

2. Check and Adjust Tire Pressure

Tools Required: Tire pressure gauge
Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires to match the recommended PSI (found on the driver’s side door jamb).

3. Inspect Tires

Tools Required: Tire tread depth gauge
Examine each tire for uneven wear patterns, bulges, or foreign objects.
Measure tread depth; if tires are worn unevenly, consider rotating or replacing them.

4. Perform Wheel Alignment

Tools Required: Alignment machine
Take the vehicle to a professional alignment shop.
Follow the technician's instructions to adjust the wheel alignment to manufacturer specifications (usually toe, camber, and caster angles).

5. Inspect Suspension Components

Tools Required: Socket set, torque wrench
Lift the vehicle using a jack and secure it with jack stands.
Inspect control arms, ball joints, tie rods, and bushings for wear or damage.
Replace any worn or damaged components and torque to factory specifications.

6. Test Drive

After repairs, perform a test drive to assess if the pulling issue is resolved.
Monitor steering response and vehicle handling.
