Low back end on my 2001 or 2002 Envoy (GMC)

My Envoy's rear end airs itself up. Today it didn't do anything and seems to be very low to the ground only in the rear. What do I need to do?

I just had this problem on my Envoy on July 14, 2008, I called the guaranty company and they sent my truck to a chevy dealer, after 4 days they fixed. It was the ignition switch.

Have it tested for a leak. Do not run the compressor if you do not have to. You will burn out the compressor. Sysytem will have to be pumped with air to pin-point leak

SOURCE: rear air suspension

the air suppension has a lever on the rear axel
will want to check the lever and the sensor and make sure it hasnt come loose or bent and yes its adjustable. if it doesnt adjust you might have a bad sensor or air leak

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.

I have a 2003 GMC Envoy SLT and all of a sudden my rear axel is alomost on the ground. I can't recall doing anything or going anywhere wher this could have happened. How could be the problem and is it...


Exactly what do you mean the rear axle is on the ground? Do you mean the body in the rear has lowered? Do you have the air suspension system on your truck? If so, you may a leak in the system somewhere or the compressor is bad.

HEllo I have a 2003 GMC Envoy SLT and evey morning the rear end is down practecaly on the floor but when i turn it on the compresor lift the cars rear end back up. I do hear the leak of air in the rear...


well have you determined where the air leak is coming from???? Get soapy water and locate, could just be a fitting loose and a snug with a wrench is all. If this vehicle has an air bag and it is leaking from a puncture or crack in the bag then it has to be replaced, but check air line and fittings with soapy (dish soap ) water first.

The rear of my GMC Envoy sits very low and the ride is very bumpy


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.
