Figure 4.6 shows the standard air spring used on the suspension.
Figure 4.6
The RideSentry™ suspension uses three different air springs based
on the suspension model and ride height. Refer to the following
table for the air spring part numbers.
1. Refer to the preceding table to identify the specific air spring
that is damaged or leaking air.
2. Park the trailer on a level surface. Block the tires to prevent the
trailer from moving.
3. Use an appropriate lifting device to raise the trailer to extend
the air springs, but not enough to raise the tires off the ground.
Support the trailer with safety stands.
4. Verify that all the air has been exhausted from the air system.
5. Remove the air inlet line and fitting from the damaged air
spring. Figure 4.7.
