2003? original shocks,I assume.
Could be a loose shock bolt,loose sway bar bushing or end link bushing
Is the tail pipe touching the frame?
When it cools,wiggle the tail pipe forcefully up and down.
Crawl under there and inspect both rear shock absorber mounts and sway bar bushings and mounting bolts.
if it LOOKS good,have someone bounce the rear of the truck when you are nearby. Hear the noise? left side or right side?

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: The Heater fan in my 2003 GMC Yukon XL will not turn off

I don't know if you already fixed it, but I had the same problem on my 03 yukon, TysonRicky is right. In my case it was the blower control module. You can find it right under the glovebox. It cost me close to $100 for a new one, but very easy to replace. Can't even imagine how much it would've cost me if I had a mechanic do it.

Mark your drive shaft coincidenly with the rear axle and tranny. Remove drive shaft. Press out the old u joints and press in the new. You will need a torch for heat and a lot of patience. Have fun!

Why, after hitting a bump in the highway and braking at the same time, did my brakes fail - how can I fix this dangerous situation - my mechanic is baffled?


has your vehicle got ABS braking system ? if so i'd get the OBD codes read if not already done as may be a sensor/switch that is sending an incorrect signal to the brake system after the bump at the same time , there is sometimes a brake limiter valve fitted to the rear suspension ,if your vehicle has this component i'd have that checked as the suspension will obviously rise/fall when going over bumps , let me know how your mechanic responds to these suggestions

Might need to adjust rear door latch, or could be bad relay or switch. Try pulling/pushing on rear door while closed to see if you can set this off while sitting still.
