#238 of 247 air shocks 2004 Yukon XL
Jul 24, 2013 (7:14 am)
So I just went through the whole throttle body issue on my truck. Finally had to take it into a mechanic shop so they could find a short we couldn't find and re-flash the computer. The guy I bought this truck from is a mechanic so he knows the car inside and out. There are just some things he can't or doesn't have the time to do for me. Anyway, the mechanic shop is telling me I need new shocks. I tell this to my friend and he says its air ride suspension and probably best not to mess with it.
Now I have not actually gone and picked up my car yet. I've only talked with the desk girl who relays the messages. I found this page from skimming over posts here https://www.arnottindustries.com/part_GMC_yid15_pid96.html.
I do not know a thing about air ride suspension. I don't even know what I have on this truck because I've never had reason to look. Do these things wear out over time? I know regular shocks get replaced sometimes.
The only thing I've ever noticed about the suspension is that going over a speed bump is rough. You come down on the other side of that speed bump like the rear is filled with cement. I think it rides fine. My husband thinks it's a bumpy ride, but I tell him he is too used to driving those low sporty high dollar cars work gives him lol.
any advice on the suspension/shocks for this truck would be great. thanks.

I have a 2004 Yukon XL Denali - The air ride compressor and air shocks typically do not last much more than 100K and the sensor connections (which snap onto the top of the air shocks in fronts) typically fail since they are so close to the engine and exhaust manifold. My mechanic busted the connectors on the sensors where they connect to the top of the shocks so I was getting the ride control errors. At 100K, I replaced the compressor which failed with one sourced out from Arnotte Industries. It's worked just fine. BTW, if the compressor has failed or if the air bladders on the shocks failed, it will ride rough. You should be able to look at the shocks (with the engine running) and determine if either of these components have faield. These shocks are expensive from the dealer, but if you can get the reman OEM from Arnotte, you're going to come out smelling like a rose. My Yukon XL Denali (which has all OEM replacement shocks by Arnotte) has stabilitrac and it rides much better than my 2011 CHev Suburban LTZ.

I noticed that Arnotte has a Bilsteen spring conversion kit and I see that it's got a " kit that also includes our new cutting edge technology to reliably eliminate any fault codes on your dash panel". It's my understanding that the OEM's (with stablilitrac) has sensors that control shock dampening (depending on vehicle speeds). It sounds like the Bilsteen system disables that feature and just tricks the computer into thinking that everything is ok. I'd like to know of anyone has used the conversion kit on Yukon Denali's and what impact did it have on the stabilitrac system. The price on the kit is good, but the ride must be totally different. Any words of wisdom on this?
#242 of 247 Service ride control light
Aug 24, 2013 (5:16 pm)
I have been having this problem for a while now my service ride control light is on, and my truck rides awful. A few months ago I noticed holes in my air bags so I replaced them. After that the truck drove perfect for one day then it went right back to how it was before. I recently noticed the front of the truck sits lower than the back and a read something about the sensors on the front shocks going out so I replaced them. That did nothing now I am completely lost and I cant continue to spend all this money not to have the problem fixed someone please help.

I know this is 2+ years later, but could you tell me where you found the fuses and relays you checked? I found 1 large square fuse under the hood in the fuse panel. it controls the moon roof and air ride compressor it works and checks out fine yet I still get no air ride compressor activation.
#244 of 247 Compressor not running
Sep 12, 2013 (7:35 am)
The fuse and relay are on the drivers side above the front wheel well (under the hood).
If you jump the relay contacts and the compressor runs then something is keeping the relay from being energized by the computer.
My guess is that it is an open exhaust solenoid coil circuit. This is a common cause.
#245 of 247 Keep getting codes
Sep 25, 2013 (9:45 am)
I keep getting codes on my 2003 Denali..."service stability" occasionally and "service ride control" consistently. My check engine light is always on but nothing shows when I check this at O'Reillys. I clear the codes with their system and 2 days later it is back on. When I bought the vehicle it had been lowered so my husband put in new rear shocks and raised the torsion bars on the front, could this have caused it? Where do I begin?

Hi Im having the same problems and how do you find the spot your talking about that is corroded on the shocks. Because I have had the light on and my Compressor turns on for 20-25 seconds after I start up. I changed the compressor from the old one to a Arnott compressor which had me rebuild the dryer and that a fifth grader could do. I put it all back together and it ran like normal but I don't know what to look at next? The Shocks appear to be holding air because it runs normal on start up then turns of if it wasn't turning off would indicate a bad compressor or shock be cause it would keep running and burning out my compressor so I need to find what keeps the light on. Please help??

Do you have a Cold Air K&N intake system because if you do the Check engine may be causing this because it gets oil residue in to your MAF sensor it will go away after the Mass Air Flow sensor gets in tune with you K&N cold air intake. Messing with the level of the vehicle will definitely trigger your service air ride control. Until its level and the air ride compressor works and the sensors are leveled than the light will go away, This vehicle is an alarm night mare if you are customizing by raising the Yukon and if your changing the rims and tires you will get another code from the Tire pressure monitor service. The only way to get all the light off the dash there is away to put get rid of them by installing resistors on the components alarming but Im not how to do it.
