7. Axle/Suspension Alignment
IMPORTANT: The vehicle MUST be set to the proper
Ride Height before performing axle
alignment procedure. Refer to
Section 6 for more information.
IMPORTANT: When performing axle alignment, the
procedure must be performed on all drive
axles equipped with Neway
NOTE: The Neway
ADZ suspension is typically installed
®
by the OEM/chassis builder with one "adjustable"
frame bracket (typically roadside) and one "fixed"
frame bracket (typically curbside). The adjustable
frame bracket can be visually identified by an
alignment collar located behind the head of the
pivot connection bolt (Figure 11). There is a .5"
(13 mm) square hole in the alignment collar above
the bolt head, which is used to align the axles.
NOTE: These instructions assume that your suspension
was properly installed and adjusted by the vehicle
OEM / Chassis builder.
1.
With the vehicle unloaded and/or trailer disconnected
on a level surface, chock the front tires to prevent the
vehicle from rolling forward or backward.
2.
Support the frame with jack stands (Figure 12) and
exhaust all air from the system by disconnecting the link
from the lower connection of the height control valve
and pulling down on the link (Figure 13). Refer to
the height control valve manufacturer's instructions for
further information.
Failure to properly support the vehicle
prior to commencing work could create a
crush hazard which, if not avoided, could
result in death or serious injury.
3.
Loosen the pivot connection bolt nut on the adjustable
frame bracket (Figure 11). DO NOT remove the bolt and
nut from the frame bracket.
Removing the pivot bolt from the frame
bracket will cause the suspension to fall
which, if not avoided, could result in
death or serious injury.
