Picked up my H3 tonight after the repair and NO CLUNK so far!! I won't be 100% confident until I drive it into work and in the parking structure tomorrow, but right now I am about 95% confident that it is fixed.

They ended up replacing the driver's side leaf spring assembly, Driver's side rear shackle, and insulated the body mounts somehow. So far it is as tight as when I got it new 3 1/2 weeks ago. Let's keep fingers crossed that it holds. If everything is good after tomorrow, I'll post the detailed description from the repair order. Looks like the Tech did A LOT of work to find the problem -- really appreciate his hard work.

So far, so good!!

Bought my 07 H3x in the dead of winter. Now that the hot temps are here, it is doing the same thing. The clunking.
Two questions:
Does anyone know if Ron Carter Hummer on Gulf Freeway in Houston is knowlegeable to this situation?
Also is the GM service bulletin posted on this Forum anywhere so we can read it?

I appoligize if this has already been covered, I skimmed through this thread rather quickly. When a thread is 23 pages long, it is a ton of reading!

Bought mine at RC Hummer and hoping they are well aware of this situation so I will not have to educate them.

Thanks!
Robert

I have 9000 miles on my 07 Adventure and just noticed the noise over the last couple of weeks. This thread was great to ferret out the problem over the last year, but I do have one suggestion. Go ahead and place an update in the original post with TSB and part numbers to let people like me get to the info quickly. I am now going to notify my dealer of the problem and get things rolling for a fix.

For the record, I absolutely LOVE my H3 and the fellowship of this forum. Thanks everyone.

Greg

GM had the same problem on the HD pick-ups a few years ago. MY crew cab 2500HD clunked bad and you could feel it in the wheel. First repair was just to grease the intermediate shaft but this was only a temporary fix. Second attempt was to replace the intermediate shaft. Again, temporary. Third trip to the stealer got a redesigned shaft that was good for at least the next 75K miles. This was on an 04' and I knew of people who had the problem on 02's. You would think GM would have this taken care of by 07'. I work for GM though so I guess I shouldn't be suprised.

Got my rattle fixed this week. Good as new so far. While it was there I showed them how the driver side front sat lower than the passenger side, and that both should probably come up a bit more anyway.

So they grinned back and told me that they would crank the bars if I would pay for the alignment. Now she is fixed and leveled. A bit firmer, so I may go Cognitos pretty soon.
