GMC Yukon Noises and Sounds
Recently I noticed a thumping noise from the right passenger area that is present with the car is at idle (it is not loud enough to be heard if the car is moving) and when the ignition is on but the engine is off. Any thoughts?

Thanks!
My husband is deployed to Iraq and I'm burnt out of getting no where! I had a belt replaced about 4 weeks ago. Before this happened.
I'm trying my best to do this on my own, I have no choice, I don't like the dealership here locally but next one is 1 hr away. My service advisor back in TN always made sure any problem I had got fixed, and didn't push me aside. But stationed here in KS now....Someone also suggested cracked exhaust manifold? I just need some help here, also it seems to be when parked it idles rough/shaky since having the injectors cleaned??????
tidester, host
As far as your rough idle after your injector flush, I would run a tank of good quality gas though it and than see how it runs. They may have put in a tank additive. if you still have a rough idle, than take it back.
Hope this helps, and that your husband makes it back soon!
Anyhow, it is possible that during the process of removing and installing a fuel injector, so dirt may gotten in to the fuel rail or one of the injectors and caused the rough idle... assuming each injector was properly cleaned. Just a side note, if I'd to clean the fuel injectors I would also replace the fuel filter too(unless the filter in built in with the fuel pump inside the fuel tank, then forget about it).
I had a (small) cracked exhaust manifold once, I am not sure if I would describe the noise as a landed helicopter (sounded a bit flat, in my case it sounded more matel-ish, higher pitch); anyway, there was certainly loud Ticking sound when the engine was hot, shifter in Park or at low RPM with no load to the engine... Are you able to tell if the noise is coming from which area of the engine (e.g. top center close to the Intake Manifold, Right/Left front/rear close the valve cover, or front center close to the fan belts, and etc...)?
There is a TSB on the problem and it was fixed by the dealer on both - no further problems.
Also - the 2004 Tahoe had the "steering coulmn rattle" described earlier and that was fixed by a center shaft replacement.
All on warrenty, so I don't know the costs - sorry.
I know someone posted about this a long time ago, but I didn't see any replies.
Has anyone else had this, too????
thanks!!
Maybe the self-leveling AutoRide suspension doing something?
Do you hear it only when first driving it or can you hear it after running errands for a while?
To check if that is indeed the case, after you have backed your car out of your garage on to a straight and flat road:
1. put your transmission in "N" then let go the brake pedal (make sure the car is not rolling)
2. slide the shifter in to "D" from "N"
3. let your car "roll" forward (no need to give any gas) for a few feet
4. then press the brake pedal, see if you hear the same "popping" sound???
If you do, then there is a very good chance that one of the pads is sliding just a bit in the caliper. The pad that's sliding/hitting against the caliper caused the sound your heard. Hope that's all it is... Good Luck!
It's usually only when I'm first driving it.
What is an ABS self- test???
thanks for the reply!!!
thanks for the great instructions.. i will let you know what happens...
I want the clunk gone and have heard many different things it could or couldnt be. Like the rear leaf springs could be clapping, a clip in the transfer case, the slip yoke needs to be replaced...etc...
Has anyone else had this problem and how did they solve/fix the problem.
Thank you.

Have you talked to a GM service shop?

Did you solve your clunking problem. I have a 2000 GMC Denali and it makes the same sound as you describe.

It sounds like there are rocks inside a hubcap. Of course there are no hubcaps on this but that is what it sounds like.
Literally out of nowhere.
Any ideas?
Turns out it was a stone in the break caliper (right rear)
