Removal

Removing the front member




Remove the front member from the body, exhaust pipe and three-way catalytic converter (TWC). Remove the brake pipe from the mountings in the member.

Removing the front propeller shaft





Note! If the same propeller shaft is to be reinstalled. Mark the propeller shaft CV joint in relation to the bevel gear flange.

Remove the screws from the propeller shaft.
Use counterhold 999 7057 Counterhold 999 7057 Counterhold.

Removing the rear section of the exhaust system




Support the front section of the exhaust pipe so as not to put strain on the exhaust manifold.
Remove the rear exhaust system assembly.

Removing the rear propeller shaft





Note! If the same propeller shaft is to be reused mark the propeller shaft CV joint in relation to the flange.

Remove the screws from the joint. Use counterhold 999 7057 Counterhold 999 7057 Counterhold.
Leave one screw in place by a few threads for safety.




For cars with a vibration damper on the Active on Demand Coupling flange
Use counterhold 951 2940 Counterhold 951 2940 Counterhold.
Leave one screw in place by a few threads for safety.




Remove the screws from the propeller shaft center bearing.
Slacken off the screws in the support for the center bearing on the right-hand side a few turns. Fully remove the screws on the left-hand side
Let the center support hang down so that the propeller shaft can be angled.
Remove the screw from the joint.
Press the shaft joints together, detach it from the flange.
Remove the shaft.

Installation

Note! For tightening torques, see Tightening torque [1][2]Mechanical Specifications.

Note! To ensure that there is no exhaust leakage, see Flanged joint, assembling Flanged Joint, Assembling.

Installing the propeller shaft, front




Check carefully that the mating surfaces on the propeller shaft and flange are clean.

Note! If the same propeller shaft is to be reinstalled, install the propeller shaft using the marking made earlier. See Removing the front propeller shaft.

Tightening the propeller shaft CV joint
Use new screws.
Tighten the screws. See Tightening torque [1][2]Mechanical Specifications.

Installing the propeller shaft, rear

Note! If the same propeller shaft is to be reinstalled, install the propeller shaft using the marking made earlier. See Removing the rear propeller shaft.

Check carefully that the mating surfaces on the propeller shaft and flange are clean.
Align the propeller shaft CV joint against the flange.
Install the screws loosely in the support for the center bearing and the propeller shaft.





Tightening the propeller shaft CV joint
Use new screws.
Tighten the screws. See Tightening torque [1][2]Mechanical Specifications.




For cars with a vibration damper on the Active on Demand Coupling flange
Use counterhold 951 2940 Counterhold 951 2940 Counterhold.

Installing members and the exhaust system





Tighten:
- the 4 M8 screws for the support for the center bearing
- the 2 M8 screws for the propeller shaft center bearing.

Install:
- the front member on the bodywork, the exhaust pipe and the three-way catalytic converter (TWC), 4 x M8. Tighten
- the brake pipe in the mountings in the member
- the rear exhaust pipe assembly. Use a new gasket between the three-way catalytic converter (TWC) and the rear exhaust system.
