IMPORTANT:
Trailer MUST be unloaded before
beginning any service procedures.
1. On a level surface, support the front of the trailer with
either a kingpin stand, landing gear, or while coupled to
a tractor
(Figure 11)
.
2. Raise the trailer frame approximately 2" (51 mm) above
the suspension’s specified ride height
(Figure 12)
.
3. Place multiple jack stands at the suspension’s specified
ride height
(Table 2)
under the vehicle frame at
OEM specified locations, then lower the trailer onto the
jack stands.
Failure to properly support the suspension
during maintenance could create a crush
hazard which, if not avoided, could result
in death or serious injury.

4. Exhaust all air from the suspension, set the parking
brakes, and chock the wheels.
Failure to exhaust the suspension air
and chock the tires prior to beginning
maintenance could allow vehicle
movement which, if not avoided, could
result in death or serious injury.
5. Disconnect the linkage from the control arm and lower
the axle mounting bracket
(Figure 13)
.
6. Pin the height control valve so that the valve arm is in
the center or neutral position
(Figure 13)
