We I guess I should say something about the gear ratio, 3.92 with 33 is where I would be. I drove with that setup for many years and just loved it, good gas mileage and very good power (this was before the major mods done this summer) Gas is not getting any cheaper and we need to put that factor in, 90% dd does not need 4.56 yes if gas was going down then go for it or if you have 35 and up tires in the future. I have a new set of dana 60 s in the shop with factory 4.56 and I have a new set of 4.10 gears to go in them, yes I am swapping out the gears. It’s a fine line to get both good gas mileage and good power.

In 2wd, the cad is disengaged, so, you are probably turning the passenger side inner axle. Not something that would be evident from the outside.
That's a limited slip though isn't it? And your shaft doesn't turn in 2wd while driving??

This is stuck in my head and I may be totally wrong but the drive shaft doesn't turn in 2WD. I have a truetrac in the front and I can crawl under it w/ it in 2WD and turn the drive shaft and it doesn't turn anything else. It freely spins. If it turned while operating it in 2WD I wouldn't be able to freely turn it while it was not moving? Unless I was Superman and could turn the left front axle at the same time? I maybe totally off but that is what is floating in my head on a Friday afternoon when I'm a few drinks behind the rest of the world.
- Smooth operation
- Performs open until needed
- Fully automatic limited slip
Detroit Truetrac's proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well.
Proven design, low cost and effective performance all make the Detroit Truetrac limited slip differential the ideal choice for a wide variety of vehicle applications. No maintenance - Just Traction.

Yes it is two totally different carriers. Mine being the LSD. I'm not positive if it turns while driving in 2WD. That sounds like a test for this weekend! How dangerous is it to hang out of the truck and look underneath while driving? I love a good challenge!
I guess I always just figured the axles turned and with the CAD disconnected bc of 2WD the drive shaft didn't turn. You learn something everyday.

No worries.
I think you would have to be a contortionist to be able to see it and drive at the same time in any event.
