Tesla Model S: Mount - Front Drive Unit - RH (Remove and Replace) - Installation
Installation
- Use alcohol wipes to clean the mating surfaces between the RH
drive unit mount and drive unit.
- Place a shear plate on the outboard side of the drive unit mount
so that the shear plate bolt holes align with the motor mount bolt
holes.
Caution: Ensure that the bottom holes on the shear
plate are not slotted. If the bottom holes are slotted,
replace the shear plate with one that is not slotted.
Note: Install a shear plate even if the
original drive unit mount did not have a shear plate.
- Insert new bolts (x2) through the lower holes in the shear plate
and motor mount.
- Set the new drive unit mount into position.
Caution: Ensure that the bolts do not fall out from
the drive unit mount while maneuvering the drive unit mount
up to the front drive unit.
Caution: Do not damage the RH axle during
reinstallation.
Note: The RH motor mount is reinstalled with the
shear plate.
- Loosely install the lower bolts (x2) to the drive unit.
- Lower the vehicle.
- Alternate tightening the bolts on the support jack to raise the
drive unit. Have an assistant monitor the installation from the RH
wheelwell and underhood area to ensure that the bolt holes align
correctly.
- Working from the RH wheelwell, hand tighten the bolts (x2) until
they are snug; do not fully torque the bolts at this time.
Tip: Install the forward bolt first. Have an assistant
help align the rear bolt hole with the hole in the body.
- Align both lower bolts with the front drive unit. If equipped,
install the torque reaction arm shear plate on the drive unit mount.
Note: The lower holes (x2) on the torque reaction
arm shear plate are slotted.
- Hand tighten both lower bolts.
Note: The support jack might and/or drive unit
might need to be slighlty adjusted when installing the lower
bolts that secure the mount to the drive unit.
- Hand tighten the upper bolts (x2) that secure the mount to the
drive unit.
- Position the 3 shim tools between the RH drive unit mount and
body.
Note: These tools ensure proper clearance. Leave
them in place until prompted to remove, after all 6 bolts
for the mount are fully torqued.

between the mount and outer bushing.
- Reach downward between the V-brace and cross brace and
position the straight shim tool between the mount and inner
bushing.
- Working from the RH wheelwell, fully torque the bolts that
secure the mount to the body (torque 120 Nm).
- Raise the vehicle.
- Attach the 15 mm ratchet tool to a torque wrench.
Caution: Ensure that the attachment is 90 degrees
perpendicular to the torque wrench when using the tool.
Note: Only use the ratcheting tool on the front 2
bolts.
Tip: A Crowfoot wrench can be used in place of the ratchet
tool.
- Fully torque the bolts (x4) that secure the drive unit to the
mount in the order shown (torque 75 Nm).
- Lower the vehicle.
- Verify fitment of the alignment shims. Adjust as necessary.
- Remove the shim tools.

cross car beam (torque 6.5 Nm).
- Install the RH bolt that secures the A/C compressor bracket to
the front drive unit (torque 10 Nm).
- Reconnect the coolant level sensor harness.
- Install the bolts (x4) that secure the coolant reservoir to the
cross car beam (torque 6 Nm).
- Install the fir tree clips (x2) that secure the 12V positive
harness to the front cross car beam.
- Install the 12V battery and bracket beam (refer to procedure).
Caution: Do not connect the negative cable on the battery at
this time.
