Solution

1. Tire Inspection and Adjustment

Inspect Tire Pressure:
- Use a tire pressure gauge to check and adjust tire pressures as needed.
- Ensure all tires are inflated to the recommended PSI found in the driver's door jamb.
Examine Tire Condition:
- Check for uneven wear or bulges. Replace any damaged tires if necessary.

2. Wheel Alignment

Perform Wheel Alignment:
- Lift the vehicle on a hydraulic lift.
- Use a wheel alignment machine to adjust camber, caster, and toe angles to factory specifications.
- Follow the manufacturer's service manual for specific alignment specifications and torque values.

3. Suspension Inspection

Inspect Suspension Components:
- Visually check control arms, bushings, and struts for wear or damage.
- Replace any worn or damaged components (e.g., control arm bushings).
Reassemble and Test:
- Reassemble any removed parts and ensure all fasteners are torqued to specifications.

4. Steering System Check

Inspect Steering Components:
- Check for worn tie rods, ball joints, or steering rack issues.
- Replace any defective components as necessary.

5. Test Drive

After repairs, conduct a test drive to ensure the vehicle no longer pulls to one side and that the steering feels centered and responsive.
