To accomplish this, lift the vehicle off the ground and support it securely on jackstands, and then barricade in front of the wheels. To reach the driveshaft, take off the back part of the exhaust system. Draw a mark on how the driveshaft is related to the companion flange of differential, separate it from them by removing bolts. If the car has two sections of driveshaft, take away the middle bearing mounting bolts. Lower down the rear of driveshaft and afterward push it out of transmission through front yoke. While taking off shafts, wrap a plastic bag over transmission casing securing it with a rubber band to avoid losing fluid and for protection against contamination. The installation is performed in reverse order as its removal. If rotation has occurred on these components either by means of differential or transmission shafts; then they will not align hence leaving an unaligned shaft that cannot be put into place. Tighten attachment parts to required torque. Engage parking brake after raising vehicle's front end to be held secure by jackstands. Mark relationship between driveshaft and differential companion flange then remove bolts. Prop up transfer case using floor jack Remove mount bolts: slowly lower transfer case about 2 inches (50mm). This will help you detach the front part of driveshaft from front differential while removing splined yoke from transfer case unitize Installation procedure should be done as recounted in preceding paragraph except that new O-ring must be installed on splined yoke together with tightening drive shaft/front diff companion flange bolts accordingly.

Leakage at the driveshaft entering the transfer case (AWD models) indicates a defective transfer case seal.
