Auto ride questions

[WoldD90]

So how does it work? Does it pump air into the shocks?

On my Range Rover, it has an air bag system that you can see level everything out, even with a heavy load on the trailer.

But, I have had my 04 XL since 05 and I have never seen it adjust itself. It is a 2500 series, so the springs are super stiff.

Is there a way to test it?

AutoRide on the 2500's is different. It just adjusts the level of shock damping. It constantly adjust between firm and soft based on road conditions.

In the 1500's it does the same thing, except the rear shocks have built in air bags. When a load is put on the rear, a compressor adds air until it returns to its set level. It lets out the air when a load is taken off the rear.

Do any of you have a problem with sagging in rear springs? I've replace my shocks with Edelbrock shocks all 4 of them. The stock shocks were pretty heavy I wonder if these shocks support the weight of truck helping springs to maintain the level.

you probably had the G65 self leveling shocks... those use lighter rate springs and carry part of the load via the shock, so replacing shocks only leaves you with sagging springs.

Thanks...That helps.

Is there anything else I should know about the Autoride?

Yeah, the feature makes the car ride smoother than it would if it was not there and the shocks break/leak oil pretty commonly.

Thanks... I appreciate all the help.

Interesting as I have the 2500 Yukon XL. I am doing the level kit and noticed the front left shock leaking when putting the shock extender on. If I went with Bilsteins made for the 2500, will this throw a code on my dash light? The only thing I saw hooked up to the shock was on the top bolt.

The front shocks on an autoride vehicle have an electronic damping feature that adjusts the damping according to road / cornering forces. If you replace them with ones that don't have this feature then yes the dash light will come on but it can be overcome with a resistor wired in place where that connector is on the top. There are several write ups on that. I believe it's a 3.9 ohm 25 watt wire wound resistor, found on EBay. Cut the connector off, wire the resistor in its place.

Thanks for that. I will run a search for that mod. Debating on replacing with a like shock or go Bilstein.

I went with Arnott's shocks. They come with bypass modules that I ended up replacing with resistors since the ones they supplied failed under their lifetime warranty. The shocks are great. I believe my problem was my cats got plugged, causing excessive heat at the exhaust manifolds which caused their bypass modules to fail since they sit right next to the manifolds. Arnott is a pretty inexpensive option.

I see the AutoRide (Z55 option) as a great feature. I don't agree with guys that say it doesn't work well when towing. Quite the contrary. I've been towing boats for years, and love the AutoRide. I've replaced the entire system over the last few years, for a total cost of about $1200. Rear air shocks, compressor, front electro-magnetic shocks. It all works well, and is worth keeping if you tow.

Rears were Arnott shocks, Dorman compressor. Fronts were Monroe 40044.

Bought my truck with 74k on the clock. Air compressor has never kicked in since I bought it a little,over a year ago. But I have a very close family friend who is a whiz mechanic. Gonna have him figure out why the compressor doesnt kick on @ startup. I've ridden in several Denalis that have working autoride and it's super nice.
