What did you do to your NNBS GMT900 Tahoe/Yukon Today?

If your crack is his snap we gots a problem.

I thought about that after I wrote it and laughed at the way it fell out. Decided not to change it. It's a little comforting to know I'm not the only one amused by such.

Wait, what about 3rd row or jack ? Maybe its inside? Ideas....

Good points, but it’s definitely coming from under the truck on the passenger side. Isn’t the jack on the driver’s side? Driven without the third row in place and the sound was still there.

It’s not a major concern, per se, more an annoyance while,everything else is so nice and quiet. Meh...

lol... you actually read it all?

I'm a highly sophistimicated, mofo. Also subtle, very subtle.

How are your motor mounts? How about the transmission mount? My old 2005 made a similar noise and I found the bolt on the trans mount was loose.

Was talking about your posts in general...

The sound is in the rear, so no tie rods or struts to deal with. Tried the wheel shaking and it didn't move anywhere.

Shocks look good, but at 8 years and 130K miles, might not be a bad idea to consider changing them. As well as the struts in the front, of course.

ok, then did you check the bar that goes across behind the rear axle, it looks like a flat panhard bar (I don't know the name of it, but is it a panhard type bar), single bolt on each side, over time it wears out a bit and will make a clank noise, I had to replace mine, but you may get away with tightening it down real good and see if the noise goes away
looks very similar to this

So I found out how to disable the default backup lines on my head unit so I can use the better ones integrated in the camera. Nothing you can't learn on YouTube these days...

Much better:

You bring up a good point. I have a broken LH mount (and maybe a broken trans mount, too) and I swore the sound was coming from the back. Once I discovered what was making the sound, it now sounds like it's more towards the front. Just had to trick my mind... or is it "un-trick" it?
