Product Details

Common Problems This Part Can Address

• Front wheel bearing noise or growling
• Hub play or looseness at the wheel
• Uneven wheel rotation caused by worn hub components
• Service delays from a worn or damaged front hub assembly
• Replacement needs on high-mileage Camaro, ATS, CT6, or CTS front suspension service

Installation Notes

Verify the vehicle’s front hub configuration, stud count, flange bolt pattern, and ABS sensor arrangement before installation. Because the ABS sensor is not included, reuse or replace the sensor as required by the vehicle. Clean the mounting surface thoroughly and torque fasteners to factory specifications during installation.
