I found this today on gmtechlink.com, for those who experience the driveline tink. I have not yet but then again my 05 hasn't cracked 1000miles yet ;) .

Propshaft Noise Some owners of a 2002-05 Chevrolet TrailBlazer EXT 2WD, or GMC Envoy XL 2WD, or 2003-05 Chevrolet SSR may comment on a ping, pop or click noise from underneath the rear of the vehicle. This concern usually occurs when shifting into Reverse, or out of Reverse into Drive.

On TrailBlazers and Envoys equipped with a 3.42 axle ratio (RPO GU6), or a 3.73 axle ratio (RPO GT4), this condition can be corrected by replacing the original swaged aluminum propshaft with a straight tube propshaft from the GMC Envoy XUV.
- p/n 15113111 for vehicles equipped with the 4.2L L6 (RPO LL8)
- p/n 15113110 for vehicles equipped with the 5.3L V8 (RPO LM4).

The propshafts mentioned above CANNOT be used in TrailBlazers and Envoys with the 4.10 axle ratio (RPO GT5). If this concern appears on a vehicle with the 4.10 ratio, use p/n 15163667, which is the same as the original propshaft.

On Chevrolet SSRs, a revised propshaft for automatic transmission vehicles p/n 15247556 was released for service, which includes an integral mass damper, mounted on the slip-yoke (transmission end) to improve a driveline whine concern. Manual transmission (6-speed) vehicles use p/n 15209860 which has a larger rear u-joint to fit the 9.5-inch rear axle. These propshafts have also been changed internally to reduce the ping, creak or click noise when the direction of the propshaft is reversed.

FiveOh: Thanks for finding and posting this!

I have saved myself a copy for future use if needed.

It proves that GM knows that BOTH the "tink" and the "whine" (I actually call it "ringing") exist, and that GM believes that both are caused by the prop shaft, not elsewhere.

Valuable.

Question: Is the replacement driveshaft from the Envoy, the "STRAIGHT tube propshaft from the GMC Envoy XUV. p/n 15113110 for vehicles equipped with the 5.3L V8 (RPO LM4)" aluminum or steel?

Hey Jim, on the same page on the very bottom of the gmtechlink page ( July ) there is a section called " fix it right the first time ". I found this in there, which you may find relevant due to your overheating debacle. Hope this helps.

Fiveoh: This is GREAT info. I am goin to try to get the text of the service bulletin referred to (bulletin 04-06-03-004A - replace cooling fan fuse and/or repair wiring harness, don't replace fan. It IMPLIES that there might be a wiring harness issue that is maybe leading to, or related to, the fan failing to come on?

I'll contact the dealer here in Santa Fe and see if they can get me the text.

Ok, here is the text of the 04-06-03-004A bulletin:

http://www.alldata.com/tsb/General-Motors/1110441600000_1115276400000_04-06-03-004A/404.html

It basically says that the cooling fan can be fried if the vehicle is ever jump started or the battery recharged by attaching to terminals other than the correct two remote terminals in the engine compartment (the +ve and -ve terminals clearly marked on either side of the engine).

Apparently, some dealer service techs have been incorrectly using the 1P Positive battery terminal stud at the fuse block, and thus frying either or both of (a) the cooling fan and (b) the roof door module.

Thsi could explain why some of us have had cooling fan and/or roof operation issues!

Make sure your dealer reads and understands this TSB before doing anything electrical on your SSR!

Huh?

Hey Jim,

Thats' what my dealer did to my 03.They ran the battery down demonstrating the top and just before I was supposed to take delivery, they blew the fuse to the cooling fan and the engine overheated and vented some antifreeze.
I havn't had any other troubles

Thanks to you guys I have now started my very own "Potential :ssr Problems and Solutions" notebook that I will forever carry in my truck :) Bought a 3-ring binder and some document protectors, printed out the info, and put it in the truck. Hopefully, we won't ever experience these problems (or unknowledgeable techs :mad ) but will be prepared for them in advance.

Guess what! The battery was dead on my 05 when I picked it up at the GM pep lot in Pontiac. The lot fellow helped us out by jump starting my R. I have suspected that I might have a over heating problem. Thanks to you and this information I now have something new to check out. So tomorrow it's time to find out if my fan works. Great helpful site. Scheide.

My tink has actually gone away after eight months of ownership. The noise (when shifting into reverse) was not there originally but after a couple of months became quite noticable (I must back up the beast to get it out of the garage each morning). Now I don't hear it at all. I can't imagine anybody getting concerned over this until the drive shaft ends up on the pavement (but then again what gets some people concerned is probably where a lot of shrinks make their money).
