Remove the nuts (x3) that secure the air spring module top mount (torque 39
Nm).
Raise the vehicle.
Note the orientation of the clip that secures the brake hose to the air spring
module. Release the clip.
Remove the nut and bolt that secure the air spring module to the lower arm
(torque 140 Nm).
Caution: Take care not to damage
component(s).
Caution: Replace all nylon-insert
locknuts.
Note: The following image shows a rear wheel drive (RWD) air spring module. The
air spring module in a dual motor (DM) vehicle looks different.
Carefully compress the air spring module and release it from the lower
arm.
Release the air pressure line from the chassis rail clip.
Maneuver the air spring module to access the air pressure line.
Caution: Thoroughly clean the air pressure line ports prior to
disconnection. Failure to maintain cleanliness will adversely affect system
performance.
Undo the collar and remove the air pressure line (torque 5 Nm).
Caution: Plug pipe connections to
prevent ingress of moisture or dirt.
Remove the air spring module.
Caution: Ensure that you do not damage the halfshaft if removing an
air spring module from a DM vehicle.

Installation
Installation procedure is the reverse of removal, except
for the following:
Caution: Replace all nylon-insert
locknuts.
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.
Ensure that the clip that secures the brake hose to the air spring module is
installed correctly.
Rear wheel drive (RWD) vehicles: The hose and the clip are
installed from the same direction.
Note: Ensure that the clip is fully seated,
with the “fingers” both remaining on the bottom side of the retaining
bracket.
