Removing
Secure front exhaust pipe -A- with tie-down strap -T10038- to intermediate support for propshaft.
Loosen clamps -arrows- and remove rear section of exhaust system. Remove the soundproof cover under the power unit.
Unscrew bolts -1- and -2- for lower power unit support.
Loosen bolts -arrows- for propshaft intermediate bearing by approx. two turns.
wring out «engine and gearbox» hand forward and fix them in this position with a suitable piece of wood -A-.
To avoid noise later due to imbalance. If there are no marks -arrows-, mark the position of the propshaft in relation to the flange on the main drive.
Unbolt the flexible coupling from the final drive. Lay a rag on the crossbar of the tunnel. Remove the cardan shaft together with the flexible coupling and place it on the tunnel cross member.
Instruction: Sufficient free play to the flexible coupling is required to remove the Haldex coupling.
To do this, you only need to release the cross member of the tunnel, but do not unscrew it. Position service crane tray -VAS 6208- under final drive.
Unscrew the drain plug -A- and completely drain the oil from the Haldex coupling.
Unplug connector -2- from all-wheel drive control unit J492-.
Position service crane tray -VAS 6208- under final drive. Screw in drain plug -A- with a new O-ring and tighten to 30 Nm. Unscrew securing bolts -arrows- and remove Haldex coupling from rear final drive.
Installation is carried out in the reverse order. All components whose mutual position relative to each other has been marked must be installed in their original position. Fit new seal -arrow-, after lightly lubricating with Haldex coupling oil.
Insert the Haldex clutch into the rear final drive. Tighten bolts -arrows- to specified torque. Connect connector -2- to four-wheel drive control unit J492-. Tighten driveshaft. Loosely align intermediate support and secure. Tighten the cross member of the tunnel. Attach the lower support of the power unit «new» bolts. Install exhaust system (make sure there are no distortions). Install soundproofing. Fill with new oil for Haldex couplings, check the oil level in the Haldex coupling. Tightening torque: Haldex coupling to rear final drive - 50 Nm.
