What to do if an Air Spring
Ruptures
If an air spring is ruptured, drive the vehicle
to a safe stop off the highway to investigate
the problem.
WARNING
Do not continue to drive with ruptured
air springs. The air loss can cause the
spring brakes to apply allowing your
brakes to drag and burn up the linings,
which could lead to an accident caus-
ing death or personal injury. Do not
continue to operate the vehicle in this
condition.
WARNING
Do not drive the vehicle if the air pres-
sure is less than 100 psi (690 kPa).
Driving the vehicle with less than 100
psi (690 kPa) could make the brakes
unsafe to use which could cause an
accident involving death or personal
injury.
CAUTION
Operating a vehicle with air suspen-
sion bags either overinflated or under-
inflated may cause damage to drive-
line components. If a vehicle must be
operated under such conditions, do
not exceed 5 mph (8 km/h). Failure to
comply may result in equipment dam-
age.
You can get to a repair facility by removing
the height control link connected to the
axle and to the suspension air valve control
arm. This will cause the air valve control
arm to center in the closed position.
Removing the link will allow the air system
of the truck to operate normally so that the
vehicle can be driven to a service center.
