Snapped the short shaft
Well after 60K miles and untold launches the short shaft snapped.
Unfortunately its not the easily replaceable shaft that most vendors carry.
Fortunately Chris @ Speed Demon found one for me.
I've heard stories where guys have had to buy the entire rear end just to get ahold of one.
I should have it back on the road by Wednesday if all goes well.

Re: Snapped the short shaft (Scott97)
You are the second to snap the short shaft, according to GM. Because I was the first. But mine was on my FIRST dragstrip launch.
I fought GM on the warranty/cost issue. Almost lost bigtime, but the rep decided to let me slide and we agreed that I would pay a $300 decuctible. Total cost was about $2500 for an all new diff, install labor and realignment. Whew!

damn....I'm getting ready for a set of 3.73s and was already planning on the hardened output shaft but wonder if there's something out to beef that up too :)

Re: Snapped the short shaft (Mean Green 2000)
Where is the short shaft? I'm really not all that familiar with the diff in these cars. I'm used to the solid rear axle of the f-body.
Good luck scott, hopefully we wont be pushing your car off the strip again anytime soon.

I'm not doing the warranty thing for this, so I haven't taken it to a dealer.
Chris is doing me a deal on the part, but its upping my bill a bit, but no where near what it could be

Re: Snapped the short shaft (Chris@SpeedDemon)
The short shaft is the passenger side output shaft...it has an integral side gear in it. The failure occurs where the gear and the shaft meet. The splines on this shaft are what the passenger side axle/joint slides into.
GM lists no failures of that shaft....meaning, I'm the only guy on record who showed up wanting it fixed under warranty. This is according to my dealer who I actually trust for several reasons, and the rep, who knows I broke on the starting line.

Re: Snapped the short shaft (Scott97)
Cliff99C5hardtop broke one around last September IIRC. It was the first short shaft failure I heard about, I have tried to keep an eye out for those sorts of failures. Damn few examples out there.
I haven't decided whether or not I think it's better to have hardened shafts and push the weak link out to like the half shafts or keep it in the diff. I'm inclined to think in the diff is easier to deal with... Anybody have a half-shaft failure and can comment on how much collateral damage there was? And maybe even some autopsy photos? :)

Re: Snapped the short shaft (Scott97)
This is one of the inherint problems with dragracing our cars. This is why F-Bodies are better suited with the solid rear axle. I think Xtreme sells a set of hardened output shafts one for both sides..unless it is something else I am thinking of. Just curious..out of all you guys that have done this what tires were you using when it happened. I know a few months back C5Pig busted his..but he had many runs and I believe got into the hi-10's running H&C, 4:10 gears, and MT/ET streets...maybe it is the way some are driving. The only reason I am asking is because I am getting ready to drop in some 3:90 gears and am wondering if I should go ahead with the output shafts.

Re: Snapped the short shaft (Shinobi'sZ)
I broke on stock tires, stock 03 Z, 2400 miles on the odo.
I dumped the clutch at about 3800, had an instant of massive wheelhop, and never moved an inch. BANG!
I don't believe that anybody is selling the short shaft, probably due to the extreme difficulty of machining this shaft with a gear on one end. [last December, there was a similar thread, and LPE said they don't make one or know of any] It's not just something you can make on a lathe and a mill and then heat-treat it. Cutting a gear is not for the average shop. Gear machines are big money, and the potential market is quite small. As far as my dealer and the rep say, the shaft is not available as a seperate part from GM, so it might be awhile before you see anybody taking a stocker and treating/hardening it. And that probably wouldn't help much, anyway.

Re: Snapped the short shaft (ToplessTexan)
I broke my short shaft at the track and I think I was the first case out there with this problem. Corvettes of Houston warrantied the problem for me since I purchased the complete rear setup from them.
I think that there is someone out there who does sell both hardened shafts. I think that it would be worth it.
