2. Jack up the vehicle and place it on jack stands.
3. Disconnect the exhaust system on a double clamp and remove the exhaust system bracket from the subframe. Tie up the exhaust pipe without bending its flexible section more than 10°. Remove the rear of the exhaust system from the double clamp.
4. Remove the heat shield under the cardan shaft and remove the bolts (see illustration 7.11) its intermediate bearing by about 4 turns.
5. Remove the rocker from the transmission by removing the bolts (B and C in Figure 5.20 of Chapter 6).
6. Check for color marks on the flex plate of the cardan shaft and on the flange of the Haldex coupling (see illustration 7.9). Apply these marks as needed.
7. Turn out bolts of fastening of a cardan shaft to a flange of the coupling Haldex (see illustration 7.10).
8. Together with an assistant, press the power unit forward (arrow on resist illustrations) and insert between the subframe (IN) and transmission (WITH) suitable wooden block (A) approximately 50 mm thick. At the same time, remove the cardan shaft from the centering pin of the Haldex coupling flange in a horizontal direction so as not to damage the gaskets (see illustration 5.21 of chapter 6) in the flanges of the cardan shaft.
11.8 Installing a block between transmission and subframe
9. Tie up the cardan shaft (And on the opposite illustrations) suspended (IN) exhaust system.
11.9 Locking the cardan shaft
10. Disconnect the connector (2 in illustration 9.3).
11. Place a drip pan under the Haldex coupling.
12. Remove the filler plug (And in illustration 4.41 d of Chapter 1), remove the drain plug (IN) and drain the Haldex coupling fluid. Tighten a new plug with a new seal to 30 Nm.
13. Turn out bolts (see resist. illustration) and remove the Haldex clutch from the rear final drive.
11.13 Haldex coupling bolts
14. Replace O-ring (see resist. illustration). Lubricate with Haldex coupling fluid when installing.
11.14 O-ring
15. Installation is carried out in the reverse order. When docking the clutch with the rear final drive, you can use the guide pins; rotate the clutch flange if necessary to align it with the rear final drive. Tighten the Haldex coupling bolts to 50 Nm.
16. Finally, fill the Haldex coupling with working fluid (see Section 4 of Chapter 1).
