Replace entire AirRide System or Convert to Passive?? - 2003 Denali

[Merc1973]

Check your rear ride height sensors? Those metal rods rust out. One on each side connected to frame and upper control arm.

I'm so glad there is a thread for this. I have been riding mine for a week now with service ride control. My compressor is shut and may have a leak from shocks somewhere. I was looking into craigslist to see if I can salvage parts from a parting-out add. Looks like I have a few options.

Just bought my 2001 suburban used with 212,000 miles, everything is clean except my autoride is not working.
If I jump the ALC relay under the hood the compressor kicks on but the shocks do not air up which tells me they are leaking. I confirmed rear shocks or not holding air, do I need to replace all the shocks and the compressor or just the rear shocks?

 

[Rocket Man]

Hard to say. You shouldn't have to jump the relay to make the compressor come on though. It should just keep running if the shocks are leaking. Which would most likely have ruined the compressor though. You can try just replacing shocks and then try running the compressor by jumping the relay and see if they hold air. At which point you'd know the shocks and compressor both work and then you'd have to still troubleshoot why the compressor isn't coming on by itself. I suspect they're all shot and the system has been disabled.

anyone ever tried these? There are replacements for the original air shocks. No bypassing or anything. I currently have holes in my rear shocks and am debating on switching to non air shocks but these replacements seem cheap enough.

I also found these, anyone know if these will work on a 2006 tahoe LT

I wouldn't buy either of those. The Arnott ones you linked aren't actually rebuilt- they're only partially rebuilt. The actual shock portion is just tested and painted but they do add new air bladders. I've heard of trouble with those, but Arnott DOES sell new air shocks of their own. I've been running them for 2 years as well as their compressor and front shocks. They don't have electronic damping but I don't miss it. It has a resistor built-in so you can just plug the wire in so there's no messages in the DIC. As for the other EBay one you linked, I've never heard of that brand. They look like junk to me. Here's the rear Arnott Premium ones.

so no issues with bypassing the system like that? To be honest i dont really like or need the air system Im just not sure what is need to switch over to regular shocks in the back.

 

[pizzle]

Air shocks are just in the rear, correct?

 

[Rocket Man]

It doesn't bypass the air system, only the electronic damping which is the system that changes the damping rate of the shocks. And no there should be no issues.

 

[Rocket Man]

And correct the air shocks are rear only.

maybe im confused there. So the compressor still fills the shocks? what is the damping system?

There is a typical hydraulic filled shock absorber(damper) with an airbag wrapped around it. The airbag can be thought of like a helper spring, it is not a damper.

 

[pizzle]

so the compressor fills the airbag?

 

[TheAutumnWind]

so the compressor fills the airbag?

Yes, automatically.

Ohhh... you are asking about this?

This shock bypasses the vehicle’s often problematic auto-damping system and includes a sensor which plugs into the electronic controls to eliminate dash panel error messages.

The shock absorbers (dampers) have electronically variable valving. The premium arnott shocks are a standard shock and do not have electronically variable valving, however they do have air bags as you can clearly see. These shocks maintain the vehicles auto levelling ability with the bags. It is simply the variable valving that is commonly problematic that is eliminated in this particular case. Does that help?

Autoride systems also have the electronically variable valving in the front shocks as well, they do not have the air bag that is present in the rear however.

yeah i think i got it. this operates the compressor without the damping system

Correct. And like I said, you'll never realize they even HAD electronic variable damping after it's gone. Money would be better spent on quality sway bars and endlinks to help with what that was supposed to do.

I think I want to switch to regular shocks at this point

You can do that too. You'll need to replace the rear springs since and disable the "service ride control" message. Lots of info here on those.

you think that will work. Im still not really sure about the service ride control part yet.
