In all actuality if the fuse was pulled a warning message about servicing the suspension would show up. The only way it wouldn't was if a resistor was connected inline to the pump.

#71 - STUD 1 for the compressor

Pulled the fuse and changed it with another (same amps)...no dice. It leads me to believe the pump is shot and it's burnt out because I'm sure the shocks are leaking. What stumps me though is no warning message. How could I tell if there is a resistor somewhere? I checked the shocks all oem connections are in place and the pump looks undisturbed. Where else can I look?

You can check the connectors on the front shocks and the rear compressor connector for a block like resistor. Similar to the pic below.

Just checked again. I dont see anything? I even pulled #71 Stud 1 and started the truck no warnings lights at all. I'm stumped.

I ordered all new sway bar bushings and sway bar links. Cheapest place to start then if that doesn't help I will make the leap to shocks. I'm tempted to replace the air shocks with "normal" shocks. Would I need stiffer springs?

Stiffer springs I hardly doubt it unless you want shorter springs to drop the rear end a little.

No, I'm good with the height. Pump is shot and shocks are as well. I have no warnings lights. I'm going to unplug the connectors off the rear shocks and drive it and see if I get an error. If I don't. I will yank the pump out and replace the air shocks. It will be much cheaper than replace it all back to OEM. Searching for replacements now just don't know what to go with.

Well fixed the swaying. Both front sway bar links were broken. The back were ok, but changed them as well. Yanked out the air compressor it was shot. Will be replacing the rear shocks with some passive air shocks along with a new dorman pump. Thanks everyone for your help!

There's also a panhard bar that runs parallel to the axle. It lets the axle slide left and right as the suspension travels. I've found mine to be bad and replaced it to clear up that problem. The bushings on it get pretty beat up.

GMPARTSDIRECT had mine for about $65 shipped. I believe they call it a track bar in the parts catalog.

Rear upper and lower control arm bushings seemed fine in both my vehicles under 100k miles.
