Removal
- Loosen the front RH wheel lug nuts (x5).
- Remove the HV battery (refer to procedure).
-
Remove the bolts (x2) that secure the coolant pump bracket to the body of the vehicle.
- Disconnect the electrical connector from the battery coolant pump.
- Carefully secure the coolant pump away from the working area.
- Lower the vehicle.
- Remove the 12V battery bracket beam (refer to procedure).
-
Release the fir tree clips (x2) that secure the 12V positive harness to the front cross car beam.
-
Move the 12V positive harness to the RH side of the vehicle to keep it out of the working area.
-
Release the bolts (x4) that secure the coolant reservoir to the cross car beam. Do not remove the reservoir at this time.
-
Carefully lift up the coolant reservoir and disconnect the coolant level sensor harness.
-
Remove the RH bolt that secures the A/C compressor bracket to the front drive unit.
NoteThis allows the jack strap to slide between the front drive unit and the compressor.
-
Release the bolt that secures the coolant pump to the LH side of the front cross car beam.
- Remove the bolts (x4) that secure the front fuse boxes to the front shock tower crossmember. Move both fuse boxes behind the cross car beam.
-
Position the support jack on top of the cross car beam and secure the screws (x2) to the cross car beam.
NoteThe support jack mounts to the bolt holes that secured the coolant reservoir.
- Fully lower both mounts of the support jack.
-
Position the RH strap between the front drive unit and the A/C compressor:
- Lower one end of the strap over the top of the support jack and behind the front cross car beam.
- Reach beneath the drive unit and pull the strap upwards.
- Secure the two ends of the strap with the carabiner.
- Slide the strap so that the carabiner is approximately 6 inches (150 mm) above the front cross car beam.
-
Raise both sides of the support jack alternately until the strap is fully taut.
CAUTIONEven though only one strap is used in this procedure, it is important to raise both sides of the support jack.
- Raise the vehicle partially and remove the front RH wheel.
- Release the plastic rivets that secure the rear of the upper front arch liner and then pull the arch liner forward.
- Fully raise the vehicle.
-
Remove and discard the upper forward bolt that secures the mount to the drive unit.
-
Release the lower forward bolt that secures the mount to the drive unit.
NoteThe lower bolt cannot be completely removed at this time.
- Lower the vehicle.
- Release the edge clip that secures the coolant pump hose to the body of the vehicle. Move the coolant hose away from the working area.
-
Working from the RH wheelwell, use a socket wrench with an extension to remove the bolts (x2) that secure the mount to the body.
-
Remove and discard the upper rear bolt that secures the mount to the drive unit.
-
Release the lower rear bolt that secures the mount to the drive unit.
NoteThe lower bolts (x2) cannot be completely removed from the mount at this time.
- Raise the vehicle.
-
Remove the RH drive unit mount.
NoteManeuver the mount between the coolant hoses during removal.
-
Remove and discard the lower bolts (x2) from the drive unit mount.
- If equipped, remove the shear plate from the drive unit mount.
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 and align the bolt holes.
NoteInstall a shear plate even if the original drive unit mount did not have a shear plate.CAUTIONMake sure 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.
-
Insert new patchbolts (x2) through the lower holes in the shear plate and drive unit mount.
-
Set the new drive unit mount into position.
CAUTIONMake sure that the patchbolts do not fall out from the drive unit mount while maneuvering the drive unit mount up to the front drive unit.CAUTIONDo not damage the RH axle during reinstallation.
-
Loosely install the lower RH drive unit mount patchbolts (x2) into the drive unit.
NoteThe support jack might and/or drive unit might need to be adjusted when installing the lower patchbolts that secure the mount 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 make sure the drive unit mount bolt holes align correctly with the bolt holes in the body.
-
Working from the RH wheelwell, hand tighten the bolts (x2) that connect the drive unit mount to the body; 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.
-
Install and hand tighten the new upper patchbolts (x2) that secure the mount to the drive unit.
-
Position the 3 shim tools between the RH drive unit mount and body to ensure proper clearance.
NoteLeave the shim tools in place until prompted to remove them.
1 2-pronged shim tool. Working from the underhood area, position the 2-pronged shim around the RH drive unit mount front bushing. 2 Hook shim tool. Reach beneath the drive unit and position the hook shim tool between the mount and outer bushing. 3 Straight shim tool. 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 low profile socket to the torque + angle wrench.
- Set the torque + angle wrench to a torque value of 35 Nm.
-
Tighten the bolts to the RH drive unit mount (torque 35 Nm) in the sequence shown:
-
Set the torque + angle wrench to 75 degrees of angle and tighten the bolts to the correct angle in the sequence shown:
- Lower the vehicle.
- Remove the shim tools, then attempt to reinstall them:
- Lower the support jack and release the strap from the drive unit.
- Release the screws (x2) that secure the support jack to the cross car beam. Remove the support jack from the vehicle.
- Install the bolts (x4) that secure the front fuse boxes to the front shock tower crossmember (torque 5 Nm).
- Install the bolt that secures the coolant pump to the front cross car beam (torque 6.5 Nm).
