Tesla Model X: Rear Halfshaft Assembly - Small Drive Unit - LH (Remove and Replace)

Special tools required for this procedure:

1. Drain the fluid from the drive unit (refer to procedure).

   Caution: Plug the transmission opening to prevent ingress of dirt or moisture.

   Note: After removing the lug nuts, remove and discard the axle nut (torque 245 Nm). The axle nut must be replaced during reinstallation.

    

2. Release the ABS harness from the bracket on the subframe.

    

3. Release the axle from the knuckle.
4. Remove the axle from the vehicle.

Installation procedure is the reverse of removal, except for the following:

Caution: Ensure that the new halfshaft has a snap-ring already installed. If it does not, then install a different halfshaft that has a snap-ring already installed. Return any halfshafts without a snap-ring using the MRB process. Do not remove or reuse snap-rings.

• Apply approximately 1 gram of Molykote M-77 Lubricant Paste to the outboard side of the halfshaft to the hub mating face.

  

• When installing the halfshaft into the drive unit:
  • Ensure that the opening of the snap ring is facing towards the bottom of the drive unit.
  • Do not damage or displace the oil seal.
  • Verify that the halfshaft is fully seated by carefully pushing it into the drive unit until there is an audible "click" from the snap ring.
• Pump the brake pedal at least 5 times to seat the pads against the brake rotors.

Warning: Always check that the brake pads are seated correctly before driving the vehicle.

Caution: Ensure that the bolt that secures the spring assembly to the knuckle is inserted towards the rear of the vehicle; the head of the bolt faces the front of the vehicle and the nut is tightened at the rear.

• Perform a four wheel alignment check (refer to procedure).
