Warning: Refer to Safety Glasses Warning in the Preface section.

Danger: To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed and strap the vehicle to the hoist.

Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
Remove the intermediate exhaust assembly. Refer to Exhaust Crossover Pipe Replacement.
Remove the propeller shaft heat shield. Refer to Exhaust Heat Shield Replacement - Center.

Note: Observe the orientation of the rubber couplings with reference to the differential flange and the transmission flange. This will minimize the potential of incorrect propeller shaft installation.

Mark the rubber coupling (1) in relation to the differential flange (2).

Note: With the aid of an assistant or suitable jack support the propeller shaft (2).

Remove the rubber coupling to differential flange retaining bolts (1).

Note: Observe the orientation of the rubber couplings with reference to the differential flange and the transmission flange. This recommendation will minimize the potential of incorrect propeller shaft installation.

Mark the rubber coupling (2) in relation to the transmission flange (1).

Note: With the aid of an assistant or suitable jack, support the propeller shaft.

Note: Torque prevailing nuts with are single use parts and must be discarded after removal.

Remove the rubber coupling to transmission flange retaining bolts (1) and torque prevailing nuts (2).

Discard the nuts.

Note: With the aid of an assistant or suitable jack support the propeller shaft (2).

Remove the centre bearing to body retaining bolts (1).
Disconnect the propeller shaft (2) from the differential flange.
