To remove and install the component, first raise the front end up and support it on jackstands. After that, you'll need to matchmark and remove the driveshaft, then the wheels and brake calipers Using an inch lbs, measure and record differential rotational torque. Use a torque wrench on the companion flange nut. Take hold of the companion flange and unscrew the locknut. Then, utilizing the puller, remove the companion flange. Use a center punch to deform the seal and pull it out from the bore. Use a sealer to cover the outside edge of the new seal and then drive it in using seal driver. After that coat the lip of the seal with clean gear oil. Apply chassis lube to the companion flange and install it along with the nut, tightening until the rotational torque measured earlier is achieved. Do not exceed 130 ft. lbs. torque on the nut. (176 Newton meters). In the end, installation of driveshaft should be followed by filling any lost gear oil.
