Hey Don,

I have my busted tcase intact...... you want to disect it online..... gota be after t-day.....and not all at once. I'll post as we take it apart.....
interested ?????

Slurp!!

[LouZ]

Slurp!!

I'll get back to you after the t-day. Since I don't know much about t-cases....I think I'll get your input as to what to do and post movies/pics. And we'll go from there. Happy turkey day.....

I assume that, since you're posting this in a public forum, that the rest of us will be welcome to participate (or observe)?! :wink:

ooh ooh ooh, I wanna see too! I Know nothing about them either, but am a willing and able student so I will just sit back here and watch!

We all want to see this lou!!!!!:thumbs_u:

If you want... I'll assemble the results in the wiki in a nice format...

sounds good

This'll be interesting for sure.

I am intersted in how much torque the stock TC can handle before it surrenders

[RandomAccess]

I don't think we'll be able to tell that from tearing it apart... but since Lou is the first to make one surrender...

What do you guess you are getting to the crank Lou? 550 HP?

I guess it's time for someone to start making some more flexible driveshafts? I'd be interested to see how they are breaking. With Mitsubishis the problem was always rooted in imbalanced traction between front and rear over stressing the shaft and shearing the output shaft into 2 pieces.

I'll find out when I get this thing tuned in a couple of weeks...

would flexible drive shafts have helped in lou's case? If I understand correctly, It was the transfer case skippling gears and blew itself apart that was the cause.

Take a look at this. The LX AWD system is like no other.

That is certainly interesting. Very nice write-up on that! So it seems that on these cars the center diff is combined in the transfer case vs Mitsubishi style where the diff is in the trans and the transfer case is just a gearset. If what you are destroying the gears I don't think there's much you could do besides make stronger gears, or possibly weld them into a locked diff. The best thing to do is going to be to soften the shock as much as possible. The load difference from front to rear i'm sure is still a facter as it's still extra stress on the gearset, it looks like. A more flexible driveshaft would definitely help as it will help absorb shock in the same way that a wrinkle wall tire does. I know the Mitsubishis are a totally different system but it's still similar enough to compare in this respect, I've seen AWD Eclipse/Talons go from tossing transfer cases every other pass to never breaking again after switching to slicks and a aluminum driveshaft. Drag radials and such just seem to cause more problems than others, radials shock the drivetrain hard when they hook, and even harder when trying to hook. How picky is the diff about fluids? Using a thicker fluid could help as well. I've always had great luck with redline shockproof in differentials. It seems to protect the gears extremely well. Some people would be surprised how easily a fluid change can be the difference between reliability and gear stripping on some cars. Of course the weight of the vehicles isn't making this any easier.

Interesting specualtion, but Lou's is the only case that has failed. So there is no real data upon which to base a "cure".

This is true... but I've been thinking about a fluid improvement of some kind in the future.
