Chevrolet 24236607 Transfer Case

Disconnect the cable from the negative terminal of the battery, 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, disconnect all electrical connectors, and detach the vent hose from the top of the transfer case. Free the wiring harnesses and fuel lines from the retainers on the transfer case, and remove any transmission-to-transfer case support braces. Raise the transmission enough to remove the transmission mount, then support the transmission on a jack or jackstands. Support the transfer case with a jack, preferably a special jack made for this purpose, using safety chains to help steady it. Remove the adapter-to-transfer case nuts, ensuring not to lose the washers. Make a final check that all wires and hoses have been disconnected from the transfer case, then move the transfer case and jack toward the rear of the vehicle until it is clear of the transmission, keeping it level during this process. Once the input shaft is clear, lower the transfer case and remove it from under the vehicle. Inspect the transfer case gasket and replace it if damaged, avoiding the use of silicone sealant as a substitute. Installation is the reverse of removal, ensuring to tighten the transmission-to-transfer case nuts to the specified torque.
