Installation Notes and Tips

Verify axle position, seal dimensions, and vehicle configuration before installation. This part is listed for front left and front applications, with some Ford Ranger, Explorer, Aerostar, and Bronco fitments requiring specific axle ratios or hub configurations. Confirm the axle type and notes shown for your vehicle, especially on Ford F-250, Ford F-350, and 4WD applications. Clean the bore and sealing surface thoroughly before pressing the seal into place.
