My envoy sags at the rear. Looks like a low-ri-der! usually bumps up, but as time goes by it gets worse. Had it repaires under warrenty but dealer never got it right. Is there a way to defeat the system and set the system to stay up? Is there a fluid resivoir fot the system I need tio keep full? Help!

an envoy isnt a S-15 there are a cople things you can do and that's to check to make sure the ittings are tight and not LEAKING and see if th epump works. If that happens it could be bad air bags/shocks or jus ta plain leak.......
