Installation Notes and Tips

Inspect the steering knuckle groove before installation and replace any retaining ring that shows corrosion, distortion, or wear. When servicing the front wheel bearing on a Fiat 500, install the ring with the new hub unit so the bearing is secured correctly and the assembly seats as intended. Verify the ring dimensions match the application before assembly.
