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.
Raise the rear of the vehicle using the vehicle's lift points.
Refer to procedures provided by the vehicle OEM.
3.
Support the vehicle frame using jack stands and remove
the tires (Figure 28).
4.
Using floor jacks; support the axle at the axle bowl and
the lower control arm assembly at the transverse beam
(Figure 28).
IMPORTANT: Be careful NOT to gouge or mark the
transverse beam with the floor jack.
Gouging or marking the transverse beam
could cause component failure and loss
of vehicle control which, if not avoided,
could result in death or serious injury.
5.
Using two (2) floor jacks, support both sides of the lower
control arm assembly near the pivot connection (Figure 28).
Failure to properly support the suspension
during maintenance could allow the
suspension to fall which, if not avoided,
could result in death or serious injury.
6.
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 29). Refer to
the height control valve manufacturer's instructions for
further information.
7.
Disconnect the air supply line from the air spring.
NOTE: If the air spring has a leak and is deflated, Step 7
MUST still be performed.
