Suspension Service Instructions
8.
Re-position the new pinion plates on the upper axle
bracket according to the position determined in Step 7.
9.
Re-install the rear V-Rod attachment bolt (making sure
the spacer washers are in place) and re-torque the bolt to
the torque specification listed in Section 16. New hardware
is recommended to achieve proper fastener clamp load.
Refer to SRK-683 in Section 4.
10. Increase the suspension air system reservoir pressure in
excess of 70 psig (4.83 bars) and check for leaks. All
air springs should inflate and raise the suspension to
the proper ride height.
11. If designated pinion angle has been achieved, remove
floor jack from under the axle bowl and blocking from
the axle.
8B. Crossmember Positioning (if required)
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 20).
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.
Using a floor jack, support the axle at the axle bowl and
block the axle to prevent it from rotating when the bolts
are removed from the frame crossmember assembly.
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.
4.
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 21). Refer to
the height control valve manufacturer's instructions for
further information.
5.
Remove the crossmember fastening hardware that attach
the center section of the frame crossmember to the four
(4) wing plates (Figure 22).
6.
Refer to the Pinion Angle Reference Chart later in this
Section to determine the appropriate crossmember
position (1,2 or 3) to achieve your desired pinion angle.
7.
Re-position the center section of the crossmember
forward or rearward to position 1, 2 or 3 on the wing
plate depending on the position determined in Step 4.
8.
Re-assemble the crossmember fastening hardware
(Figure 22) and re-torque to the specification listed
in Section 16.
9.
If the designated pinion angle has been achieved, remove
the block and floor jack from the axle.
