Installation Notes

Confirm rear application, spline count, flange dimensions, and ABS encoder style before installation. Follow the OE service manual for axle nut torque specification, and inspect the mating surfaces, seal area, and hub mounting points during service. Because the ABS sensor is not included, reuse or replace the sensor as needed based on the vehicle condition.
