Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat, level surface.
Disconnect the battery if working on electronic components (steering assist).

2. Tire Pressure Adjustment

Using a tire pressure gauge, check the pressure of all tires.
- Adjust the pressure to the recommended PSI as specified in the owner’s manual.

3. Align the Wheels

Tools Required: Alignment machine, torque wrench, socket set.
Raise the vehicle using a lift or jack stands.
Remove the wheels to access the suspension components.
Adjust the camber, toe, and caster angles according to manufacturer specifications using the alignment machine.
- Typically, the toe should be set to 0.05 degrees for optimal performance.
Reinstall the wheels and lower the vehicle.

4. Suspension Component Replacement (if necessary)

If any suspension components (control arms, bushings, tie rods) are damaged, remove and replace them.
Sub-steps:
- Use a socket set to remove the damaged component.
- Install the new part and torque to manufacturer specifications (e.g., control arm bolts typically at 75 ft-lbs).
- Recheck alignment after replacement.

5. Final Inspection

After completing all adjustments, perform a road test to confirm that the vehicle no longer pulls to one side.
Monitor steering response and tire wear over the following weeks.
