Proper installation ensures smooth wheel rotation, accurate alignment, and effective braking. No specific operational adjustments are typically required after correct installation.
7. Maintenance
Regular inspection of your vehicle's suspension components, including the wheel bearing and hub assemblies, is recommended as part of routine vehicle maintenance. Look for:
- Unusual noises (grinding, humming, growling) from the wheel area.
- Excessive play or looseness in the wheel when checked with the vehicle lifted.
- Uneven tire wear.
- Vibrations felt through the steering wheel or floorboard.
While the Dorman 951-112 is a sealed unit and does not require lubrication, ensuring surrounding components (like brake pads and rotors) are in good condition will contribute to the longevity of the hub assembly.

If you experience issues after installing the Dorman 951-112, consider the following:
- Noise or Vibration: Recheck all mounting bolts for proper torque. Ensure brake components are correctly installed and not dragging. Verify that the lug nuts are tightened to specification.
- ABS/Traction Control Light: Confirm that the ABS sensor (if applicable) is correctly connected and not damaged. The Dorman 951-112 is designed to integrate with the vehicle's ABS system.
- Wheel Looseness: This indicates a critical issue. Immediately re-check all fasteners and ensure the assembly is correctly seated. Do not drive the vehicle if there is any detectable wheel looseness.
If problems persist, it is recommended to have the vehicle inspected by a professional technician.
