8. Lower the frame to the correct ride height.
9. Tighten the 1" fasteners to
470 ± 25 foot pounds torque.
1. The upper air spring brackets are
identical. The bracket with the
air spring locating holes closer
together is the front bracket and
should be mounted closest to
the front hanger. The bracket with
the locating holes further apart
is the rear bracket and should be
mounted furthest away from the
front hanger, see Figure 9-7.
2. Install the upper air spring brack-
ets against the frame.
3. Install the mounting fasteners.
4. Clamp the upper air spring bracket against the frame flange.
FAILURE TO CLAMP THE AIR SPRING BRACKET AGAINST THE UNDERSIDE OF THE FRAME WHILE
TIGHTENING THE AIR SPRING BRACKET CAN RESULT IN COMPONENT DAMAGE AND PERSONAL INJURY
OR PROPERTY DAMAGE.
5. Tighten all air spring bracket mounting fasteners to the vehicle manufacturer’s specified torque.
The air spring combination stud is on the outboard side of the frame rail.
6. Install the ½" studs in the bottom of the new air springs and tighten to
25 ± 5 foot pounds
torque.
7. Assemble the air springs to air spring frame hangers by inserting studs into appropriate holes.
The ¾" combo stud faces outboard of the vehicle.
8. Install the air springs into the trailing arm assembly by inserting the studs into the trailing arm
mounting holes, see Figure 9-8.
Depending on the frame height of the vehicle, it may be necessary to compress the air spring to
facilitate installation into the frame bracket and trailing arm.
9. Assemble the washers and locknuts which connect the air springs to the trailing arm assembly
and tighten the locknuts to
25 ± 5 foot pounds torque as shown in Figure 9-8.
10. Assemble the washers and locknuts on the combo studs which connect air spring to the air
spring bracket. Tighten the combo stud locknuts to
60 ± 10 foot pounds torque as shown in
Figure 9-8.
11. Install the air fittings to the air springs using Teflon thread seal.
12. Install the air lines to the air springs. Lower the frame, if necessary, to connect the air springs
and the shock absorbers.
1. Install the upper shock hex bolt in the upper shock mounting bracket prior to mounting the
bracket to the frame, see Figure 9-9.
2. Mount the upper shock mounting bracket to the frame.
3. Install the shock absorber on the upper shock mounting bolt.
4. Install the ¾" washer and locknut, tighten at this time.
