Transfer Case of its oil, then pull out either the front or rear driveshaft in order to gain access to the yoke and seal that have to be replaced. On early models, remove the output shaft nut, washer, rubber seal, the front yoke if you're servicing the rear flange, or simply the rear flange itself if it has to be removed but maintain the indexing marks on the flange and shaft so that they can be easily aligned when you are replacing them. In later models, a snap-ring holds the front driveshaft yoke in place; replacing this seal requires disassembly of the transfer case and some degree of dismantling to get to the snap ring. If you intend to replace the yoke, then take off the dust seal around the opening and apply a seal remover to gouge out the oil seal. For installation, one needs to check the oil seal contact surface for scoring or burrs and if any need to be eliminated. Spread multipurpose grease on the oil seal lip and fit it into the output shaft housing bore in such a manner that the broad side or the side which was not previously lubricated should not be installed on the flat surface of the shaft Put it into place using a seal driver or hammer with a large socket. , before installing the splined shaft on the end of the driveshaft make sure the transfer case output female splines are cleam and that you grease them. Some machines have a front yoke or rear flange that snugs onto these splines; then, there is a rubber seal, steel washer, and a new nut is put in and tightened to the specified torque.
