Question about 2004 GMC Envoy

2004 GMC XUV rear air shock failure

My Envoy has a dragging tail. The compressor seems to run but the rear of the vehicle sits down on the stops. Looks like a low rider including the back breaking bouncing ride. An auto repair shop (reputible one) looked at it when it first started to leak down and could not find the problem. Where should I start? Thanks for your help!!

I don't know were to start, it seems that the mechanics don't have a solution to this problem, could you tell me what can be done?. You may send me an e-mail to hughb13@aol.com.

Chances are that your leveling sensor is the problem this is located on the shocks themselves.

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.

What if my rear drops on my load leveling suspension on 2004 gmce nvoy


That means the air has left the shocks. The compressor may have a bad fuse or have stopped working all together. The level sensor may not be operating either.

I have a 2004 GMC Envoy xuv and my rear shocks keep losing air. I think they are made w airbags. I was just wondering if they can be patched up or do they need all new airbags and where can u find new ones...


The air bags should be strong and not leaking themselves. It may be a valve on the bags or the plastic line going to the back that is leaking.
Some soapy water sprayed on the air ride items may show bubbles from where its leaking. Like checking a tire for leaks.

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.

2004 GMC ENVOY XUV, spare tire system stopped working


The tools are under the second row seats. The hole for the spare tire lowering mech. is above the rear bumper when you lift the tail gate. Put the proper tool down the hole, turn counter clockwise, lowers spare. Reverse to bring up.
