Mopar 52111198AB Seal-Axle Drive Shaft

Disconnect the cable from the negative battery terminal, then raise the vehicle and support it securely on jackstands. Remove the skid plate if equipped and drain the transfer case lubricant. For the front output shaft seal, remove the front driveshaft. If the model has a companion flange, remove the companion flange nut and flange from the transfer case, tapping the companion flange off the output shaft with a brass or plastic hammer. For models without the companion flange, remove the front driveshaft seal boot clamp and slide the boot from the transfer case slinger. Carefully bend the slinger away from the transfer case and remove it from the shaft, possibly using a punch and hammer to loosen it. Pry out the old seal with a screwdriver or seal removal tool, ensuring not to scratch or gouge the seal bore. Lubricate the lips and outer diameter of the new seal with multi-purpose grease, place it in position square to the bore with the garter spring facing inward, and use a seal driver or a suitable equivalent to drive the seal into place, starting with light hammer taps until it is recessed correctly. Install the seal slinger and driveshaft seal boot, securing the boot with a new clamp. If equipped, install the companion flange onto the transfer case output shaft, tighten the flange nut to the specified torque, and then install the front driveshaft. Finally, remove the jackstands and lower the vehicle. The procedure for the extension housing seal replacement is identical to that of the transmission.
