#2844 of 3279 Reposting, for the record....[bcb1]
Apr 06, 2005 (11:31 am)
I am reposting this for the record; it was removed because of a (minor!) TOS violation, which I corrected. There's some info here that bcb1 and possibly others with similar issues might benefit from.
[Regarding TSBs relating to exhaust rattle in '00 Yukon:]
Could be this one:
36. ENGINE AND ENGINE COOLING Bulletin Number: 3121
Bulletin Date: JAN 2004
Vehicle: 2000 GMC Yukon
EXHAUST VIBRATION RESONANCE OR MOAN. (2004-2005 GMC DENALI) *SC
Or this one:
76. ENGINE AND ENGINE COOLING:EXHAUST
SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE Bulletin Number: 020605005A
Bulletin Date: DEC 2002
Vehicle: 2000 GMC Yukon
EXHAUST / MUFFLER HEAT SHIELD RATTLE, POPPING NOISE UNDER VEHICLE. *TT
I'm not sure which one it might be--there may even be others I missed.
In general, you can find your TSBs and recalls through Edmunds'
'Maintenance' pages. Just go to edmunds.com, click 'Directory' in the upper
right corner, and click on 'Technical Service Bulletins.' This will take
you to a page that will allow you to pull up customized maintenance
info and TSB/recall info for your vehicle. This is one of Edmunds' best
and most under-appreciated features, in my view.
As to what the specific fix was...I think they actually had to replace
the muffler as it may have been an integral heat shield or internal
baffle. I'm not sure and didn't really ask, since it was taken care of
What the service manager at my dealership (Barlow GMC/Pontiac in Woodbury, NJ, which I recommend highly!) did was let me come in with the truck
warmed up so it was doing it, and then take a drive with me so he could
hear it--I'd gotten pretty good at getting it to do it by then--and
then he got out of the truck, had me hold the brake down and rev it to the
rpm range that caused it so he could hear it from outside and get a
better idea of where it was coming from. He may even have gotten it up on
a lift later and repeated this sort of procedure while listening
underneath the truck to pinpoint it further.
I don't think the approach of shaking things by hand will work to find
it; I think it's a 'sympathetic vibration' type of thing that only
happens at certain rpms (at least that's the way my truck was).
#2845 of 3279 Radar Detector Install - Firewall hole?
Apr 07, 2005 (9:30 am)
I am installing a built-in Radar/Lazar unit on my 03 Denali XL. My hold up, and I have not checked this out much yet, is running the wires from the engine compartment into the cabin. Any recommendations on where to penetrate the firewall for the least amount of problems?
Also, is there a fused/switched circuit that is easy to tap into?

As I recall from 2001, I used an existing grommet on the drivers side.

Thanks - I think that will work.
What about power? Is there an easy switched source or do I need to hookup a relay setup off of the DAB?

My 2002 Denali developed an exhaust rattle at 50K. After installing
GM straps around the muffler , thinking it was a heat shield problem, we
discovered it was a loose pipe connection in the pipes before the muffler.
Since the fitting was fully tightened we spot welded it and the noise went

I got an easy switched source, but it was 3 years ago and I don't remember where I got it. Most likely the fusebox under the hood.
#2850 of 3279 When is GMC coming out with a new body for the denali
Apr 12, 2005 (4:46 pm)
Hi,, im about to buy a yukon denali and was wondering if anyone knew the inside scoop on when the new body was coming out,, it its coming out that is,,, and is it worth it to buy the car now that i have read many posts about so many problems with the dashboard lighting up,, ,thanks so much

As to the new body, I haven't heard anything. Try looking at the Edmunds Future Vehicles pages or googling '2006 Denali' or '2007 Denali' or 'GMC model changes' etc., and seeing if anything pops up....
As to the 'dashboard lighting up', it's the first I've heard of it, and I read here pretty frequently...where did you see these 'so many posts' you refer to? Does anyone else who frequents this board know what he's talking about?

I haven't heard any problems on this board or any of the others regarding the dash lighting up.
However, I have read that GM is pushing forward the intro date on the new full size SUVs (GMT900) and wants them in dealers by Jan 1 2006.
I'm eagerly waiting to see the next generation and whether or not the Denali and Escalade will actually be getting V10s as some are speculating. I'm still smitten with my '02 though! Definitely a keeper for me.

I have an '02 also, Garnet Red with a sunroof, and I still feel like a kid in a candy store every time I get behind the wheel.
