Leave the car running. Raise the end that you want to lower to where the vehicle is just above level. This will make the height sensor tell the control module that the end of the vehicle you raised is too high. The control module will open the solenoids in the struts, and open the solenoid at the compressor. Once the air is successfully purged. About 2 minutes. You can then shut the vehicle off. Turn the air ride switch off. Lower the vehicle.
spring struts
No.
OEM air suspension? on board compressor
Depends on what you're driving. Most cars have gas shocks and some have air shocks. Air shocks are more comfortable, with an automatic leveller, as in Lincoln Continental, in my opinion.
It may very well have shocks in the rear or it may have the Air Ride system. Crawl under the car and look see.
It's either the control arm bushings or the rubber mounts for the shocks.
A 1988 Lincoln Towncar has shocks in the front.
You might try installing a set of coilover shocks for about $75.
You have to replace with springs and shocks
Auto parts stores sell a kit with springs and shocks that replaces the rear air bags with springs. Been there, done that.
the air suspension sensors for each air shocks are located on the top of each air strut, two in the trunk and the other two under the hood.
one of the bags is broken or something wrong with the lines just go to shocks! i have a 93 and a replaces the front bags 2 times or each side in two years i just took some shocks off of a some other car
