#28 of 62 Re: Help needed for my Autoride system [bsharris67] by kiawah Nov 23, 2008 (3:32 pm)
Replying to: bsharris67 (Nov 23, 2008 11:42 am) First thing I'd check is whether the fuse is okay. Look in the owners manual fro the correct fuse, and meter it out to check that it's okay. No meter, swap it with another fuse of the same amperage. My service manuals are temporarily packed in boxes and moved while the room is getting redone, or I'd look up which fuse it was for you.

Replying to: kiawah (Oct 25, 2008 1:16 pm) thanks for your posts. you seem to understand the underlying mechanisms on the Yukon Autoride system. I have an '02 Denali standard body that looks like the ride level sensor thinks the vehicle is going up a slight grade (rear end is 2-3" higher than the front.   Is there any way to adjust for this back end high position? How about aftermarket replacement shocks with air lift capabilities? GMC wants two arms and four legs for what appears to be simple airshocks.

Replying to: BlownEagle28 (Nov 26, 2008 7:04 pm) Assuming the problem isn't in the front "not being pumped up enough", then you can adjust the height of the back. On each wheel's suspension component, you'll find a small leverarm that runs between the spring axle, and the vehicle frame. When the vehicle is carrying more weight, it compresses the distance between the frame and the axle, it is sensed by the airride sensor (via that leverarm), which then sends an electrical signal back to the airride pump solenoid to "pump up the pressure".   If you look at that leverarm, it is adjustable. Make the arm longer, it will in effect cause the vehicle to be raised up. Make the arm shorter, it will lower the vehicle.

#32 of 62 Autoride Sits Too High In Rear by BlownEagle28 Nov 29, 2008 (9:12 pm)
Thanks Kiawah!   I'll check it tomorrow morning. The system is fully functional and engages the pump mechanism when I load the trailer hitch. Will let you know what I encounter with adjusting the load arms.   Eagle
#33 of 62 Need AutoRide Suspension Package? by 2178 Dec 05, 2008 (6:59 pm)
I am about to purchase a new suburban and it does not have this feature. I tow a car trailer with car 2,000 miles periodicallyand the total weight is about 6,000 lbs. Seldom tow 11,000 lbs but only 5 level miles. Is having this feature essential?   2178 Replies to this message: ahightower (Dec 07, 2008 9:01 am)

Replying to: 2178 (Dec 05, 2008 6:59 pm) What was your previous tow vehicle?   I wouldn't say Autoride is necessary for the situation you described, but most people who have it seem to really like it. Not knowing any better, I personally wouldn't pay the extra $$$ for it, but I don't tow great distances with any regularity   I've only towed once with a 19' travel trailer (rented), and will go again with a 24' next week. But we frequently load up with five people, all our camping gear, and a loaded hitch haul platform hanging off the back for ice chest, firewood, etx, and I've never had it sag in the rear. (05 Yukon XL 1500) It "levels off", but I've never felt it was overloaded with regards to weight. All that to say that the load you described should not cause the rear end to sag on a Suburban with the standard suspension.   What I'm most interested in when we eventually trade up, is the new 6-speed transmission that's standard for 2009. We have the 4-speed auto and 3.42 gears, and it does provide relatively good fuel economy. But when towing, I kept the speed around 55-60 mph and avoided cruise control, otherwise the transmission would want to kick down fairly aggressively to maintain speed on the slightest incline. I believe it had more to do with the wind resistance of the trailer than the weight (only 3500-4000 lbs).   Now, if I was going to tow long distances frequently, I'd seriously consider a 2500. A cousin has one and says while he barely gets 12 mpg unloaded, downhill, with a tailwind, when he does tow, he doesn't even feel the trailer back there and has no problem maintaining higher speeds.   Anyway, that's my two cents, maybe someone else will chime in for you.
#35 of 62 Process for abandoning Autoride? by bert77 Dec 12, 2008 (9:33 am)
I'm having continuous troubles with my 2001 GMC Yukon XL autoride system. I had the compressor replaced last spring and it worked great all summer. This fall all that changed. The compressor started to running more frequently and intermittently without any load and then began doing nothing under load. After a diagnostic test at the dealer, they told me I needed a new ride control module for $1200. Pricey part...for a truck with 150,xxx miles.   I elected to purchase the same part from a salvage yard and had it installed. I took the truck back to the dealer to have the system reprogrammed and the same DTC C0660 code comes up again. They continue to point to the module as being the problem, but I'm concerned it may be something other than that.   I'm looking for info or suggestions on what the process is to abandon the autoride system and just have heavy duty shocks installed? Anyone got suggestions? Please help. Thanks!
#36 of 62 can autoride be installed on exsisting suburban by youbetya Jan 23, 2009 (2:00 pm)

Replying to: youbetya (Jan 23, 2009 2:00 pm) My 2000 GMC Yukon did this around 87k and the compressor was coming on more frequently than normal. So I went to the dealer and it was a leaky shocks. So at 380/per shock it fixed the problem but that is a lot of money for shocks!
