Locate the power steering motor (usually near the steering column).
Inspect the electrical connectors for signs of corrosion or loose connections.
If necessary, replace damaged connectors or the entire power steering motor.

4. Examine Steering Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering rack and tie rods for any visible damage or play.
Tighten any loose bolts and replace worn or damaged components as needed.

5. Test Drive

Reconnect the battery and start the vehicle.
Test the steering by taking the vehicle for a short drive to ensure the steering feels normal.
