Note: Tighten the special tool mounting bolts to a maximum tightening torque of 20 Nm.
11. Unscrew the left mounting bolt (1) of the subframe assembly (4), as shown in the figure below. Screw the bolt from the special tool (T10096) into this hole and tighten it with a tightening torque of 20 Nm.
12. Unscrew the right mounting bolt (2) of the subframe assembly (not shown in the picture below). Screw a bolt from a special tool (T10096) into this hole and tighten it with a tightening torque of 20 Nm.
13. Unscrew the mounting bolts (3) on both sides, as shown in the figure below.
14. Unscrew the left mounting bolt (2), shown in the figure below, then remove the support (5).
15. Screw the mounting bolts (T10486/1) into the hole and tighten them to a tightening torque of 20 Nm.
16. Unscrew the right mounting bolt (2) and remove the support (5), as shown in the figure below.
17. Screw the mounting bolts (T10486/1) into the hole and tighten them to a tightening torque of 20 Nm.
Note: Installation is considered correct when all four mounting bolts (1 and 2) on both sides of the vehicle have been replaced with the special tool fixing bolts.
18. Lower the subframe assembly by approximately 4 cm and loosen the mounting bolts.
Note: When lowering the subframe assembly, ensure that there is clearance between the anti-roll bar and the drive shafts.
19. Slowly lower the subframe assembly with the engine and gearbox using a hydraulic jack.
20. To install the subframe from the service position to the original position, it is necessary to: raise the subframe assembly on a hydraulic jack until it touches the body console on both sides.
21. Unscrew the left fixing bolt (1) from the special tool (T10096), screw in and tighten the new subframe mounting bolt to the required tightening torque, as shown in the figure below.
22. Unscrew the right fixing bolt (1) from the special device (T10096), screw in and tighten to the required tightening torque the new subframe mounting bolt, as shown in the figure below.
23. Install the left support.
24. Install and tighten the left support mounting bolts by hand.
25. Install and tighten to the required tightening torque the new bolts securing the left support to the subframe.
26. Tighten the bolts securing the left support to the subframe to the required tightening torque.
27. Unscrew the mounting bolts (2) from the device (T10486/1) (not shown in the picture below).
28. Install the right support.
29. Install and tighten the right support mounting bolts by hand.
30. Install and tighten to the required tightening torque the bolts securing the right support to the front suspension subframe assembly.
31. Tighten the bolts securing the right support to the body to the required tightening torque.
32. Remove the special hydraulic jack together with the support from under the vehicle.
33. Install the rocker support onto the gearbox, then install and tighten the new rocker support mounting bolts as shown in the figure below.
Note: Install the mounting bolt (1) in the elongated hole as far away from the gearbox and subframe as possible.
34. Install soundproofing coating.
35. Connect the universal joint to the steering shaft by moving it in the direction of the arrow as shown in the figure below. Then install and tighten the connecting bolt (1).
36. Install the cover (1) and tighten the plastic fastening nuts, shown in the figure below by arrows.
37. Remove the lock from the steering gear.
38. Perform a road test of the car.
