If you have air shocks, they could be leaking. Check that air compressor is being activated. You can test the power to the pump if needed with a voltmeter.

Many people do switch to traditional shocks which seem to last longer and are much less of a hastle.

You can go to autozone.com and register for free online repair manual if you wish to change the shocks yourself.

After sitting in the garage the rear end drops low. After driving the vehicle again the rear end raises back up again.


Sounds like you have air ride and your system has developed a leak. I suggest getting it fixed soon. You will burn up your compressor and that can get expensive.

Is it possible to lower the rear ride height on an 03 envoy xl by moving the air ride accuators?


If you can lower the actuators without damaging them, it should work. The ride height should drop the same amount that the actuators are lowered. Don't go too low or you will bottom out the air shocks.

I have a 2003 envoy where the rear end is riding realy low any ideas


I had the same problem with my '02 Envoy 4x4; had the soap test done and there were no leaks; also had the air compressor motor checked and mechanics said it was fine. The rear air bags were worn and cracked so I had them replaced. It lifted and rode at the correct ride height for a few weeks.
After having the rear air bags replaced I noticed that it was starting to not lift as before. Had another diagnostic check; the air compressor was not forcing air through the system in order to lift the vehicle. The air compressor motor was replaced. Compressor comes on and shuts off now.
Vehicle is at the normal ride height now.
Rear air bags and air compressor motor were dealership parts; unable to find after market; not recommended to replace with used parts.
I had the dealership to run the diagnostics and had another mechanic to replace the parts. Total repair for bags, motor + labor = $1500

The rear of my truck drops and the ride gets real bumpy. Also my stabilizer track light turned on saying it needs to be serviced


Hi, those have air bags (air ride) and one or both of the air bags has a hole in it and is leaking out,they have a pump that fills them up with air but when the bag goes bad the pump will fill it,then it leaks out, and back and forth. you just need to replace the faulty suspension air bag. or e-bay sells kits to eliminate the air ride and replace with springs. good luck. yz-maniac....

What should i expect to pay to replace the rear struts? my envoy drops in the rear making mommy's car look like a low rider. it comes up once i turn on engine, but it's slow to do so.


You car has air ride suspension. The problem may or may not be the air springs, there are no "struts", have a shop check them for leaks.
