What It Helps Address

• Wheel bearing growl, hum, or rough rotation
• Front-end vibration related to hub runout
• ABS warning light concerns tied to wheel-speed signal issues
• Uneven braking feel caused by hub instability
• Excessive play or looseness at the front wheel hub

Installation Notes

Verify the vehicle’s front hub dimensions, spline count, bolt pattern, and flange configuration before installation. This part is listed for front positions only, and the fitment notes specify bearing flange mounting holes are non-threaded on the covered applications. Confirm ABS connector routing and sensor alignment during service, and inspect related suspension and brake components for wear before reassembly.
