Not yet, I haven’t had much time to explore more. Pretty sure it isn’t the trans as I tried to rotate the driveshaft in every gear and couldn’t. I might have time tonight to try some things.

It’s the torsen. 99% sure.

I stuck the axles back in the diff and turned the driveshaft while not allowing the axles to turn. The axles wanted to turn but I’m the end wouldn’t, the driveshaft was turning.

I think it is the worm wheel under the worm gear, can’t see in there so just guessing.

There was nothing in the fluid when you drained it? If diff should've been metal chunks or glitter.

There was some glitter, and small small chunks but not as much as I would have expected. But I think that’s what it has to be

Then yes diff exploded, or else fluid would be spotless. The torsen does not handle launches/wheel hop well.

How dors the torsen handle being launched behind an auto?

Me and my buddy Ken both had torsens diffs on our pp cars,we had tons off track launches with drag radials and they held up.fine.Wheel hop will break anything trans/diff/torsen/trac loc.So if your having wheel hop during your launches something going to break!!!!.

I think its funny you waited till the third page to put that little tid bit of information out there... lol. If indeed you can turn the driveshaft and neither axle turns, then you found your problem.

Better than a manual!

It really wasn’t noticeable, I had to search for small chunks before I found any. It was the second look that I found some. I was expecting a lot more.

How difficult is to pull the torsen and put a new one in? Looks simple but I’m wondering about special tools needed or tight tolerance that take more fine tuning. Am I better just to take it to a shop and have them do it?

You might be better off buy the whole diff from a junkyard by the time you add labor and parts in. I saw one on www.car-part.com for 460.

I would go with a scrap yard diff. There are alot out there. Paid less than $300 for a 3.15 and now I dont even worry about tearing them up. $460 for Torsen sounds good.

 

[Chummel]

What about if I want to step up to a 4.10? Might as well just swap in a new torsen at the same time.
