Transfer Case

The first step for Transfer Case assembly replacement requires vehicle elevation followed by Transfer Case shield removal. Users should remove the left-side Transfer Case brace before draining the Transfer Case fluid when equipment is available. After you disconnect both the front and rear propeller shafts you should proceed to remove the Transfer Case vacuum switch vacuum line and the motor/encoder electric connector with its wiring harness. Position a proper jack stand to support the transmission after which you must take out the transmission mount retaining bolts and transmission support assembly. You should remove the transmission mount in addition to the transmission mount for automatic transmissions. A technician must help remove the Transfer Case straight back from the adapter by lowering its front section while raising the rear until the torsion bar bracket clears. Afterward the technician can take off the Transfer Case adapter retaining nuts. Replace the damaged gasket with a new one that should not receive any type of sealant. Install the Transfer Case assembly after setting the new gasket tab in an upward direction. Tighten the Transfer Case retaining nuts to 55 nm then install the transmission mount and torque its bolts to 47 nm. Reinstall the transmission support assembly followed by transmission mount retaining nuts while torquing them to 46 nm (35 ft. Lbs.). Reconnect both the motor/encoder electrical connector and the wiring harness and install the vacuum line that leads to the Transfer Case vacuum switch. You must reinstall the left side Transfer Case brace while tightening its engine bolt to 60 nm (44 ft. Lbs.) along with good tension on the Transfer Case bolt at 47 nm (35 ft. Lbs.). Reinstallation of front and rear propeller shafts is followed by fluid addition to the Transfer Case then the placement of the housing shield before the car is lowered.
