Ensure that each component is properly torqued to the manufacturer's specifications.

4. Reset Steering Assist System

Tools Required: OBD-II scanner
After repairs, use the OBD-II scanner to clear any stored trouble codes.
Follow the manufacturer's procedure to recalibrate the steering assist system if required.
