Question about 2001 GMC Yukon XL

Open Question

How much air should be in the shocks on the auto ride system on 2001 yukon xl because the front suspention seams to be riding on the rubber bushings

Looks like the lower control arms on front of my 2001 gmc yukon xl is resting on a rubber bushing and air shock not holding it up high enough . But doesn't seem to be any leak in the auto ride system and now the rubber bushing seams to be breaking down. The compressor has been replaced but I don't think it is putting enough air in the system. What air pressure should it run at and where can you check the pressure in it.

SOURCE: 2004 yukon xl denali self-leveling rear air shocks

There's a lever that connects the driver-side rear shock to the Automatic Level Control module (the air compressor and the ride-height sensor). Disconnect the lever from the shock and rotate it up and hold it. The compressor should kick in when you hold in place after a few seconds. If it doesn't kick in, make sure your fuses and relays are good. Otherwise, you may have a failed ALC module/burned out air compressor (from the shocks being shot). After you replace the shocks (and after you recouped from the heart attack you had when you shelled out $500+ for each shock), replace the ALC module/compressor (it's all one unit), and test it - it should kick on when you rotate the lever up again.

Figure about $350 for the ALC module from your dealer, and make sure the part numbers match! Your truck came with an upgraded ALC module from the 2001-2004 module, which were prone to water damage.

Good luck!

SOURCE: Auto ride on 2000 Yukon XL needs replacing.

Hey,

The air pump in located in the very back-left (driver's) side, underneath.
You know the shocks can "look" quit bad and still be okay.
Everything about this system is expensive (to me).
There is also a height sensor that can go bad and keep the air-pump from running.

I recommand an expert on this system.

Your GM Dealer is your best bet for parts.
Just my opinion.

Good Luck

Let us know,
Dave

Where is the air compressor for the ride control on 06 gmc denail


Ride control compressors burn up because of leaking air line or shocks. Replacing compressor won't last long if you have a leak. Most of these units are mounted under floor near rear axle.

It is the air shocks suspension on the rear.
When weight is added to the rear of the vehicle the ride control pump pumps up the shocks.

Service ride control


It's time to replace the rear shocks. There expensive like $250.00 and up each and if your not going to be towing, most people replace them with a good set of shocks and not the factor OEM air shock which you have for the auto ride height system. If your going to just buy and good set of normal gas shocks. Pull the fuse to     the auto ride system so the light on the dash is off.
Good luck and hope this helps. The auto ride system was there for towing heavy trailers to keep the ride hight. The rear suspension is actually soft so you have a soft ride and the shock keeps it from bouncing. If your not towing heavy or carring heavy loads, you should be fine with a conventional gas shocks and you may find it better. I found the Monroe Reflex shocks to be more stable then the OEM around corners and highway driving.

have a self test run buy the dealer on the self leveling system, most common causes are the ride height sensor, the air pump is defective or the pump relay is defective.
