Correction code 31106012

The below procedure is for models with adaptive air suspension built from April 24, 2019. For models built before April 24, 2019, refer to Air Spring Module - Rear - LH (Remove and Replace).

Note

When replacing an air spring module for failure, inspect all air spring modules for leak, wear, or reduced performance, and replace them as necessary.

Removal

Loosen the LH rear wheel lug nuts (torque 175 Nm).
Partially raise the vehicle. SeeRaise Vehicle - 2 Post Lift.
Depressurize the rear LH air spring module. See Air Suspension - Pressurize/Depressurize - One Air Spring.
Open both falcon doors and the liftgate.
Remove the LH welcome plate. SeeWelcome Plate - LH (Remove and Replace).
Remove the rear underhood apron.
Move the LH 2nd row seat fully forward.
Fold down the LH 3rd row seat.
Remove the rear load floor.
Remove the rear trunk sill trim. SeeTrim - Rear Trunk - Sill (Remove and Replace).
Remove the trunk board and trunk floor carpet.
Remove the rear load floor support.
Remove the LH C-pillar mid trim. SeeTrim - C-Pillar - Mid - LH (Remove and Replace).
Remove the LH C-pillar upper trim. See Trim - C-Pillar - Upper - LH (Remove and Replace).
Remove the LH C-pillar lower trim. See Trim - C-Pillar - Lower - LH (Remove and Replace)
Remove the LH trunk side carpet panel.

Note
Disconnect the trunk light and 12V power outlet connectors before removal.
Remove the LH C-pillar mid-zone bracket. SeeBracket - C-Pillar - Mid Zone - LH (Remove and Replace).

Remove the LH rear wheel. SeeWheel Assembly (Remove and Install).
Remove the clips that attach the rear portion of the LH rear wheel arch liner, and then move the wheel arch liner aside for access. SeeWheel Arch Liner - Rear - LH (Remove and Replace).
Release the retaining clips (x2) that attach the air line to the wheel arch.
Remove the fastener that attaches the air line to the LH rear air spring module (torque 2 Nm).
For each released end of an air suspension line, use a flat blade screwdriver to snap off the old collet, and discard the collet and nut (VOSS fitting).
Disconnect the upper LH rear air spring module connector.
Disconnect lower LH rear air spring module connector

Note
1x connector, White internals
Remove the LH rear damper harness bracket.
Loosen the bolt that attaches the LH rear upper link to the knuckle (torque 140 Nm).
Loosen the bolt that attaches the LH rear toe link to the knuckle (torque 130 Nm).
Loosen the rear bolt that attaches the LH rear lower control arm to the subframe (torque 115 Nm).
Remove the nut and bolt that attach the LH rear air spring module to the knuckle (torque 140 Nm).

Note
Pry down on the suspension to release the tension on the bolt.
Lower the vehicle to gain access to the nuts that attach the top of the LH rear air spring module to the vehicle.
Remove the nuts (x3) that attach the LH rear air spring module to the vehicle (torque 39 Nm).

Note
Move up the NVH padding for access.
Remove the LH rear air spring module from the vehicle.

Installation

CAUTION

Replace all nylon-insert locknuts.

CAUTION

Replace all patchbolt(s).

Note

Clean the affected areas before installation.

CAUTION

Only fully tighten suspension nuts and bolts when the vehicle is on a 4-post lift and the suspension is in the ride height position.

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

Make sure that all air suspension lines are securely reconnected, and then refill the new air spring module or air suspension system according to the circumstances of the repair:
- The rear LH air spring module was replaced for noise: Inflate the individual air spring with the assisted nitrogen inflate routine for that corner.
- The air spring was replaced for a leak: purge the entire system.
After installation is complete, torque the suspension components on a 4-post lift while the vehicle is at ride height:
1. Put the vehicle on a 4-post lift.
2. Remove the screws (x3) (torque 6 Nm), the bolt (torque 4 Nm) and the nyloc nut (torque 35 Nm) that attach the LH shear plate to the vehicle.
3. Remove the screws (x3) (torque 6 Nm), the bolt (torque 4 Nm) and the nyloc nut (torque 35 Nm) that attach the RH shear plate to the vehicle.
4. Remove the mid aero shield panel. SeePanel - Aero Shield - Mid (Remove and Replace).
5. Torque the suspension components to the specified torque values.
  
  Note
  Torque value for the bolt that attaches the LH rear upper link to knuckle: 140 Nm.
  
  Note
  Torque value for the nut that attaches the LH rear air spring module to the knuckle: 140 Nm.
  
  Note
  Torque value for the nut that attaches the LH rear toe link to the knuckle: 130 Nm.
  
  Note
  Torque value for the nut that attaches the LH rear lower control arm to the subframe: 115 Nm.
6. Reinstall the mid aero shield panel. SeePanel - Aero Shield - Mid (Remove and Replace)
7. Install the screws (x3) (torque 6 Nm), the bolt (torque 4 Nm) and the new nyloc nut (torque 35 Nm) that attach the RH shear plate to the vehicle.
8. Install the screws (x3) (torque 6 Nm), the bolt (torque 4 Nm) and the new nyloc nut (torque 35 Nm) that attach the LH shear plate to the vehicle.
Refer to the Alignment Requirement tables to determine whether an EPAS alignment check (EC) or four wheel alignment check (AC) is necessary. If performed, add the alignment check/adjust as a separate activity. See Alignment Requirement - Suspension.
