11. Pre-Operation
1. With the vehicle on a level surface, bring air system to
operating pressure, above 85 psig/5.9 bars.
2. Shut off the vehicle and inspect all air control system
fittings for air leaks by applying a soapy water solution
and checking for bubbles at all connections and fittings.
Examine the air springs
(Figure 19)
for equal firmness.
IMPORTANT:
It is the responsibility of the air system
installer to secure all air lines and check
for any air leaks. If air leaks are detected,
repair is required.
Failure to eliminate air leaks could
compromise suspension’s performance
which, if not avoided, could result in
component or property damage.
3. Check the shock absorbers for proper installation and make
sure that the upper and lower 3/4" shock absorber nuts are
torqued to 140-175 ft.-lbs. (190-237 N•m)
(Figure 19)
.
4. Verify that the 1/2" air spring mounting nuts are torqued to
30-40 ft.-lbs. (41-54 N•m), and the 3/4" air spring mounting
nuts are torqued to 40-45 ft.-lbs. (54-61 N•m)
(Figure 19)
.
5. With the suspension at full capacity, check that there is a
1" (25 mm) minimum clearance around the air springs.
6. The suspension’s ride height should be within ±1/4" (6 mm)
of the recommended design height. For proper height,
refer to Ride Height Adjustment Section 7.
7. Verify that the 1-1/8" pivot nut are torqued to 550-600 ft.-lbs.
(746-813 N•m)
(Figure 23)
.
IMPORTANT:
The SwingAlign
™
design maintains proper
alignment under correct torque without
welding; DO NOT weld
(Figure 19)
.
NOTE:
SwingAlign
™
pivot connections are on roadside
and fixed alignment pivot connections are on
curbside. For SwingAlign
™
Connection Axle
Alignment procedure, refer to Section 9.
8. If the vehicle is equipped with a PosiLok
™
feature, make
sure there is a 1" (25 mm) minimum clearance between
the bottom of the flipper plate and the top of the beam
pad when at ride height
(Figure 19)
; Refer to PosiLok
™

9. Check that the slider locking pins, slider pull-bar mechanism,
and slider wear pads
(Figure 19)
are operating properly.
For slider repositioning instructions, Refer to procedures
described in Section 12 of this manual.
10. Inspect the front and rear hold down clips
(Figure 19)
to make sure that they are correctly secured around the
slider body rails. Torque all 1/2" hold down clip nuts
to 75-90 ft.-lbs. (102-122 N•m).
