Installation
Installation procedure is the reverse of removal, except
for the following:
Caution: Replace all nylon-insert
locknuts.
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.
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.
Prior to attaching the air pressure line to the air spring module, ensure that
all interfaces are clean to prevent possible leaks.
