What It Helps Address

• Front wheel play or looseness from a worn hub assembly
• Noise from a failing wheel bearing at the front axle
• Improper wheel mounting caused by damaged pilot surfaces
• Vibration related to hub wear or incorrect hub geometry
• Brake and wheel alignment issues tied to hub fitment wear

Installation Notes and Tips

Confirm the vehicle year, front position, and Standard Grade application before installation. Verify the 4-stud bolt pattern, 100.0 mm bolt circle diameter, and pilot dimensions against the removed part. Because the ABS sensor is not included, reuse or source the sensor separately if the vehicle requires one. Inspect the knuckle, axle interface, and brake components for wear before installing the new hub assembly.
