They have air shocks in the back that are used for ride height control. This is not the same as an "air spring" system. They have regular rear springs and the air bladders in the shock are only pumped up when there is significant load in the rear, to prevent the rear end from sagging. This is a very simple and reliable system. Monroe makes great factory replacement rear air shocks and they are cheap too.
The Oldsmobile van has struts on the front. If it has air suspension, then the rear has struts as well. If not air ssuspension, then it just has regular shocks.
Shocks- some are air shocks. Shocked?
spring struts
Struts in the front and air shocks in the rear.

Replace the shocks, or struts if equipped.
yes it does
Its only in the rear, the air compressor is under the hood, the sensor is on the left control arm and the air bags are built into the 2 rear struts (this system usually doesnt work on a 16 year old car the rubber in the air bags rots out and they cant hold air) Napa and Sears have replacement air shocks that fit the Park Avenue. The weaker the shocks and the heavier the load the more the compressor motor runs to level the car. There is no load leveling of the front of the car. The front has tower struts, completely independent of the rear air leveling shocks.
It may very well have shocks in the rear or it may have the Air Ride system. Crawl under the car and look see.
The rear air shocks are just struts with air bags. To raise the rear in its stock way is not safe due to the fact that those struts were not made for extraordinary play. to have the best air ride is to just put an air bag system, and yes they make them in struts too so it is easy to install.
Should have "air ride" air bags The rear struts are an assembly comprising a hydraulic strut with variable actuation / dampening and an air spring, all in one unit. They are not customer serviceable, and must be replaced as a unit.
To remove the air shocks on a 1999 4-wheel drive Lincoln Navigator, first, safely lift the vehicle and secure it on jack stands. Disconnect the air lines from the shocks, being cautious of any residual air pressure. Then, remove the bolts securing the shocks to the lower control arm and the upper mounting point. Finally, take out the shocks from the vehicle and replace them with standard shocks if desired.
