Tesla Model X: Drive Unit - Rear - Large (Remove)

Special tools required for this procedure:

1. Remove the rear subframe (refer to procedure).

2. Disconnect the motor encoder.

   

3. Release the wheel speed sensor harnesses from the grommets on the subframe.

   

4. On both sides of the subframe, release the bolt that secures the upper link to the knuckle (torque 140 Nm).
5. On both sides of the subframe, release the bolt that secures the toe link to the knuckle (torque 130 Nm).
6. Use the axle extractor tool to release the halfshafts from the transmission.

   Caution: Ensure that the axle extractor tool does not contact any of the differential retaining studs.

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

   Tip: It might be helpful to loosen the nut that secures the upper link to the subframe. This provides additional clearance when installing the halfshafts.

   

   

7. Secure the gantry bolts (x3) to the drive unit. Note: Secure the short bolt to the motor section of the drive unit.
8. Loosen the nuts that secure the front and rear motor mounts to the subframe (torque 90 Nm).

   

9. Loosen the bolts (x3) that secure the motor to the side motor mount. (torque 22 Nm). Tip: It might be helpful to only use the gantry bolt that secures to the motor. This allows the drive unit to be rotated to better align the bolt holes.

   

10. Remove the bolt that secures the front motor mount (torque 90 Nm).
11. Remove the bolt that secures the rear motor mount (torque 90 Nm).

12. Carefully lift the drive unit assembly, making sure to clear the rear of the subframe.
