On 2011 models, ensure the transfer case is in the 2H position before starting the procedure. Begin by raising the vehicle and securely supporting it on jackstands. If applicable, remove the four skid plate-to-frame bolts and take off the skid plate. For models equipped with a damper, remove it from the transfer case. Drain the transfer case lubricant only if disassembling, then reinstall the drain plug. For electronically controlled models, squeeze the locking tabs labeled PUSH toward each other and pull the electrical connector apart, disconnecting it from the transfer case motor and the connector mounting bracket. If applicable, disconnect the speed sensor electrical connector and speedometer cable from the transfer case. Disconnect the front driveshaft, followed by the rear driveshaft. Disconnect the vent hose from the shift lever bracket or mounting bracket. For manually controlled models, remove the nut from the shift lever and take off the shift lever. Remove the large and small bolts retaining the shifter to the extension housing, then pull on the control lever unit until the bushing slides off the transfer case shift lever pin. Place a transmission jack beneath the transfer case and apply pressure to slightly raise it, using safety chains for stability. Remove the five bolts securing the transfer case to the transmission extension housing, then slide the transfer case rearward off the transmission output shaft and lower it from the vehicle. Remove and discard the gasket between the transfer case and extension housing, cleaning and inspecting the mating surfaces. Installation follows the reverse order of removal with some additions: install a new gasket between the transfer case and extension housing, slide the transfer case onto the transmission output shaft ensuring the splines align until it seats over the dowel pin, and install the five bolts securing the transfer case, tightening them to the specified torque. For manually controlled models, always tighten the large bolt securing the shifter to the extension housing before the small bolt. Install the vent assembly so the white marking on the hose is positioned in the notch in the shift lever bracket or mounting bracket, ensuring the upper end of the vent hose is 3/4 inch above the top of the shifter on manually controlled models. Connect the rear driveshaft to the transfer case output flange and tighten the bolts to the specified torque. Finally, refill the transfer case with the proper type of lubricant.
