- Inflate or deflate tires to the manufacturer's recommended pressure (usually found on the driver’s side door jamb).

3. Alignment Re-evaluation

Sub-steps:
- Set up the alignment machine according to the manufacturer's specifications.
- Perform a full alignment check, focusing on camber, caster, and toe settings.
- Adjust any misalignments to the manufacturer's specifications.
- Document the before and after alignment readings.

4. Suspension Component Inspection

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect the front suspension components for any signs of wear or damage.
- Specifically check control arms, bushings, and tie rod ends for play or damage.
- Replace any worn components as necessary, ensuring proper torque specifications are followed.

5. Test Drive and Final Adjustments

Sub-steps:
- Reconnect the battery and take the vehicle for a test drive to ensure the pull has been corrected.
- Monitor steering response and check for any remaining issues.
- If necessary, make further adjustments to the alignment settings based on test drive feedback.
