• Contamination-related bearing wear from failed seals

Installation Notes and Tips

Confirm front-axle fitment, spline count, bolt circle, and flange dimensions before installation. Inspect the mating surfaces, knuckle, and axle components for wear or damage that could affect hub seating or sensor performance. After installation, verify proper ABS operation and check for abnormal noise or vibration during a road test.
