How do you remove and install a transfer case?

To remove the transfer case, start by disconnecting the cable from the negative terminal of the battery and putting the transfer case in the 2WD High position (if applicable). Then, raise the vehicle and support it securely on jackstands, remove the stone shields (if equipped), and drain the transfer case lubricant. Next, remove the front and rear driveshafts, unplug all electrical connectors, detach the vent hose from the top of the transfer case, and disconnect the shift linkage (if applicable). Raise the transmission enough to remove the crossmember, support the transfer case with a jack, and remove the transfer case mounting nuts. Finally, move the transfer case and jack toward the rear of the vehicle until it's clear of the transmission. To install the transfer case, replace the gasket with a new one and tighten the transmission-to-transfer case nuts to the torque specifications. On manually shifted models, be sure to adjust the transfer case shift linkage.

Q: How do you remove and install a transfer case?
A: To remove the transfer case, start by disconnecting the cable from the negative terminal of the battery and putting the transfer case in the 2WD High position (if applicable). Then, raise the vehicle and support it securely on jackstands, remove the stone shields (if equipped), and drain the transfer case lubricant. Next, remove the front and rear driveshafts, unplug all electrical connectors, detach the vent hose from the top of the transfer case, and disconnect the shift linkage (if applicable). Raise the transmission enough to remove the crossmember, support the transfer case with a jack, and remove the transfer case mounting nuts. Finally, move the transfer case and jack toward the rear of the vehicle until it's clear of the transmission. To install the transfer case, replace the gasket with a new one and tighten the transmission-to-transfer case nuts to the torque specifications. On manually shifted models, be sure to adjust the transfer case shift linkage.
