I am assuming there is a TSB on it. The service advisor and the mechanic both told me that they already ordered the new part number and will call me when it arrives.

Chevrolet replacing driveshaft under warranty
This is probably old news to some of you, but just in case others don't know, Chevrolet IS replacing the aluminum driveshaft on my 2004 SSR with a newly designed one that includes some sort of dampers that will eliminate the "ting" sound I get right now every time I put the SSR into gear, forward or reverse, and sometimes duing gearchanges as well.
What prompted me to investigate is that I drove up to a speedshop where I am planning to get my rear axle ratio changed soon, and the experienced mechanics there instantly asked "do you know your u-joints are failing?"
I took the SSR into the Chev dealer and a Chev mechanic verified that the "ting" was there, but found out that Chevrolet has identified the cause as windup in the aluminum driveshaft followed by sudden release against the u-joints. They have developed a modified driveshaft design that includes some form of damping mechanism to prevent this phenomenon. The dealer orderd it in, and when it gets here, he will install it in about one hour of work.
I wanted to get this corrected BEFORE I had the rear axle ratio swapped, so that there can be no claim that the ratio swap somehow caused it.

Ron: I have no way of knowing whether it was a "bulletin" or "TSB". I don't really care which. It is FREE to me under warranty is all I know for sure.

Craig: The u-joints turn ut to be fine. It just SOUNDS exactly like failing u-joints would, because the cause is similar:slack movement of the driveshaft being abruptly stopped!
The Chev mechanic does NOT have to replace the u-joints. Just the aluminum driveshaft with a better one.

I just had the driveshaft installed on Tuesday. The tink IS gone! At least so far!
The warranty invoice form the Chevrolet dealer shows the following text:
F1280 propeller shaft assembly (between trans and raer differential) R&R or replace
451 W94 (n/c)
1 10371682 shaft (n/c)
Parts $0.00
Labor $0.00
Total $0.00
Hope this helps anyone who needs the info.
I think getting a custom dirveshaft made in steel could be pretty costly. I also wonder WHY GM went aluminum. Since the vehicle as a whole was built "heavy", it probably was NOT for weight reduction. There may be some other important reason.

topjimmy: Don't laugh. I DO have carbon fiber BST wheels on one of my motorcycles.
That same bike has carbon fiber: gas tank, fenders, chain guard, sidecovers, headlight shell, headlight ears, fairing, tail, clutch cover (dry clutch), countershaft sprocket cover, and exhausts.
With these, and many other changes to other parts, its stock 434 lb weight has been reduced by over 55 lb.
