Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather required tools: wheel chocks, jack and jack stands, torque wrench, alignment machine.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check all tires.
Inflate or deflate tires to meet OEM specifications (usually found in the driver’s door jamb).
Re-check tire pressures after adjustments.

3. Tire Inspection and Rotation

Inspect the front tires for uneven wear; replace if necessary.
Rotate the tires if they are unevenly worn, moving front tires to the rear and vice versa.
Check the alignment again if tire rotation is performed.

4. Alignment Adjustment

Connect the vehicle to the alignment machine.
Adjust camber, caster, and toe angles per manufacturer specifications (usually found in the service manual).
Tighten all bolts to the specified torque values (typically between 60-80 ft-lbs for suspension components).

5. Final Check

Re-test drive the vehicle to confirm that the pulling sensation has been resolved.
Check for any abnormal noises or vibrations while driving.
