2. Place a coolant catcher under the subframe fixture.

3. Release the clip that secures the coolant hoses to the subframe.

   

4. Release the clip that secures the low voltage harness to the coolant hoses.

   

5. At the front of the drive unit, release the bolt that secures the coolant hose bracket (torque 5.5 Nm).

   

6. Plug the holes for the HV cables. Caution: Do not allow coolant to enter the openings for the HV cables.
7. Release the 2 coolant hoses from the front LH side of the drive unit.

   

8. Release the 2 coolant hoses from the RH side of the drive unit.

   

9. On each side of the subframe, release the 2 grommets that secure the wheel speed sensor harness.

   

10. On each side of the subframe, release the bolt that secures the upper link to the knuckle (torque 140 Nm).
11. On each side of the subframe, release the bolt that secures the toe link to the knuckle (torque 130 Nm).
12. Use the axle extractor tool to release the halfshafts from the transmission.

    Caution: Do not let the halfshafts rest on the input seal.

13. Remove and discard the cable tie that secures the NVH pad to the drive unit.

    

14. Remove the NVH pad from the LH side of the drive unit:
    1. Working from behind the drive unit, release the hook-and-loop straps that secure the NVH pad.
    2. Working from in front of the drive unit, remove the clip that secures the NVH pad to the LH side motor mount.

       

    3. Pull the NVH pad outboard to remove it.
15. Remove the bolt that secures the front of the drive unit to the subframe (torque 90 Nm).
16. Remove the bolt that secures the rear of the drive unit to the subframe (torque 90 Nm).
17. Release the 3 bolts that secure the LH side motor mount to the drive unit (torque 22 Nm). Note: This causes the LH side of the drive unit to drop slightly.
18. Remove the bolt that secures the LH side motor mount to the subframe (torque 90 Nm).
19. Push the LH side motor mount outboard.

    

20. Move the transmission jack to the gantry area and secure the blue, red, and yellow sling mounts:

    Note: The black sling mount is not used in this procedure.
