Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the engine.
Ensure the vehicle is in gear or in 'Park' mode and engage the parking brake.

2. Tire Inspection and Rotation

Remove the tires from the front axle using a socket set.
Inspect each tire for uneven wear or damage; replace any defective tires.
Rotate the front tires to the rear and vice versa to assess if the pulling changes direction.

3. Alignment Adjustment

Using alignment equipment, check the alignment settings against manufacturer specifications.
Adjust the camber, caster, and toe settings as necessary to bring them within specifications.
Tighten all adjustment bolts to the specified torque values.

4. Suspension Inspection and Repair

Inspect suspension components including control arms, bushings, and tie rods for signs of wear.
Replace any worn or damaged components with OEM or high-quality aftermarket parts.
Reassemble any parts removed during inspection and ensure all bolts are tightened to specifications.

5. Test Drive

Reinstall the tires and lower the vehicle.
Conduct a test drive to check for improvements in pulling and steering response.
