do all escalades have air ride in the rear? I was looking around I did not see an obvious sign of an air compressor nor do I ever hear one kick on like my friends ss trailblazer. I have loaded up for the weekend two 1/2 barrels of beer, a coil box co2 cooler, and a food cooler and the rear is sagging. 78k miles now on it, the carfax said rear suspension serviced @ 40k but I do not know what that means.
They could have replaced a component at 40k and another component failed down the road. The air compressor isn't visible, it's encased behind the drivers side rear air shock in a metal enclosure. You can see the air bladder on the rear air shocks unless you purchased it used and the previous owner had it converted over to static shocks? Do you have a service suspension system message on your information center?
I do not have any service suspension messages I can just visibly notice the rear is sagging more than the front now. perhaps it is just too much weight to level or I must drive it a bit to let the compressor work? I did not start the car just turned the ignition on position to see if I could hear a compressor
Yeah you should hear the air compressor kick on at startup for a few seconds. If you visually check the rear shocks you should see air bladders and if it's sagging then they will look deflated unless the previous owner did some modifications. Heading into the dealer or a reputable shop would be your best bet to figure out what the issue is.
Looks like the stock setup. Could be either the bags developed cracks and the air compressor burned up trying to fill them or the compressor went out and the shocks are slowly loosing air...dealer can tell you or any shop.
