spring between both the lower and upper
supports. Thread the lower nuts and the
small upper nut a few turns.
2. Tighten and torque the lower stud nuts,
and then the upper nut to 20 - 25 lbf·ft (27
- 34 N·m).
3. Install elbow (if applicable), then connect
air line.
4. Connect the height control valve link.

Note:
To accelerate this operation, air reser-
voirs can be filled from an exterior air supply
connected to the accessory tank fill valve or to
the emergency fill valve.

primary air system at normal operating
pressure (95 - 125 psi (655 - 860 kPa)),
coat the air line connections and air spring
mounting areas with a water and soap
solution. Bubbles will indicate an air leak,
and none is permissible. Repair or replace
defective parts.

derneath shock absorber bracket.
