Installation Notes and Tips

Verify the vehicle’s year, front left position, and updated-design requirement before installation. Confirm axle nut thread size, hex size, and locking style against the original hardware and service information. Inspect the hub, seals, and mating splines for wear before installing the new axle shaft. Because ABS axles can fit non-ABS applications unless otherwise noted, confirm the exact brake and sensor configuration on the vehicle.
