Free the wiring harnesses and fuel lines from the retainers on the transfer case, ensuring to disconnect any post-converter oxygen sensor harness if applicable. Remove any transmission-to-transfer case support braces, then raise the transmission enough to remove the transmission mount and support it on a jack or jackstands. Support the transfer case with a jack, preferably a special jack designed for this purpose, using safety chains to steady it. Remove the transmission-to-transfer case bolts and check that all wires and hoses have been disconnected before moving the transfer case and jack toward the rear of the vehicle until it is clear of the transmission, keeping it level throughout the process. Once the input shaft is clear, lower the transfer case and remove it from under the vehicle.

Installation follows the reverse order of removal, ensuring to tighten the transmission-to-transfer case bolts to the specified torque.
