Options for a new rear diff I blew my rear diff last night. I never really beat on it at low speeds, but I punched it at 25mph and that was that. I left a 1/2 mile trail of gear oil as I coasted to find a safe place to pull over...
My dealer once claimed they will take care of me even tough I am supercharged, but this is a stretch - I am betting they deny me. Since I am guessing this is coming out of my pocket, I want it to be the last time I lay out so much cash...
So my question is, what are my options?
Madman rear - when?? wasn't there somebody trying a supra rear setup? I think I heard about a Vette rear too??
HELP!!!
Oh yeah - Out of curiosity, does anybody happen to know the parts department cost on a rear diff?

Do you happen to know how much the parts are alone?
If it ain't gonna be covered under warranty - no way in hell I am paying them to install it...
I think I found the diff itself for $1996 list.

Thanks, I just found that too. I guess that is the next best option moneywise. I sure do want the Madman rear, but I don't have the cash for it right now... I hope a new oem rear will last long enuff for me to save up...
Worst part is I was planning on going to the track tonight. I planned on getting kicked out for not having a roll cage

they cant legally deny you on grounds of having a supercharger Magnusson Moss Warranty Act.... check it on this site

Thanks for the link!
Yeah I know about Act, but they can say that this rear end was designed for less than 400whp and not meant to handle supercharged power. They can see I have a procharger, and I bet they will say that my mods directly caused the failure even though I think it would have failed anyway.
The only reaosn that I have hope is that I would try to prove that sooo many rears fail on this car, and that it would have failed anyway. Problem is that they rarely see V's at my dealer, I am thinking that CTS rear failures are mostly from leaks and whine... we will see.

Hehe - good idea, but I am way past the point of no return. I don't think that I have all the stock parts. Lots of stuff gets changed with the ProCharger...

That sucks! I don't think the Magnuson-Moss Act is going to do you any good here, unfortunately. That helps if they deny a warranty claiming some b.s. like the shifter caused the rear window defrost to stop working, but I think your interpretation is accurate - they will say that the rear was not designed to withstand that type of power. 
IMO, you've got two options: Either return the car to stock and bring it in...hoping that they haven't flagged your VIN; or, shop around until you find a mod friendly dealership.
Now, if you bought it used from a Cadillac dealership with the mods on the car, and they didn't have you sign any waiver, notices or disclaimers - you may have an argument of an implied warranty of some sort.
Good luck...that really sucks.

Thanks. I spoke to the Service manager today. He said they want to see the car, since I already complained about the rear leaking and whining. He said they might be able to cover it. We will see...
