I grenaded my transfer case recently!
Ive been looking it up, the cause, but still not sure what happened.
I think my hubs might have been stuck in locked?
This happened going over Hwy 17 in 2 wheel drive. (supposedly)
Coincidently we had to use 4wd to get out of the mud in the morning...
I haven't used 4wd in about a year! I changed the fluid just before that.
I also had to use a wrench to turn the hubs, which is why I figure they might be stuck.
So my rig is a 2000 f450 4x4.
I love the truck and want to fix it.
Biggest question I have is how hard to swap an input shaft?
Im guess mine is a 24t and all the units for sale are usually different...
I was also wondering if f450/550 are the same np271 as f250?
I will need to replace front driveline as well.
It was rotating after the driveline broke apparently, and was being held up by crossmember while still rolling.
So now it has a big ol circle indent.
Thanks for the help!
This happened to a well known FTE'r Leonard ( @FordTruckNoob ) a little while back if my memory serves me right... Perhaps he can shed a bit of light on your questions if he has a few moments in his busy schedule.

I felt a vibration start under my butt and it quickly escalated to the point where I could not pull over to the shoulder fast enough to prevent catastrophic damage. Like you, I think my hubs were stuck locked despite the **** being in the unlocked position. Mine are Warn manual lockers though.
What input shaft are you wanting to swap in? With a tcase cracked open like that, your only option is full replacement. I highly recommend getting the front driveshaft rebuilt and balanced too.
Correct me if I'm wrong but leaving your hubs locked shouldn't cause your T-case to explode unless you had your Tcase in 4wd right?
Leaving the hubs locked spins the front driveshaft which in turn spins the tcase. Any unbalanced components will cause vibration. Vibrations make tcases crack.

I guess that makes sense. One of mine is stuck locked, but I haven't really been that worried about it. I figured it meant more ujoint wear which I'm not too worried about.
Hey thanks.
Im still unsure why it ACTUALLY blew up.
I have manual hubs and have definitely drove it in 4wd high, on road, for short distances, with no probs.
I heard something about the front driveshaft slip binding?
After it blew up I called AAA.
They couldn't tow it right away and I was pulling a trailer,
so I actually ended up driving it 30 miles home and it drove perfect!
I couldn't believe it.
Its parked for good now tho.
So do you think my input shaft should be replace not swapped?
Im guessing yes...
I will replace or rebuild front driveshaft and hubs as well.
I have a zf6 so all signs point to 24t.
I guess the outputs are all the same?
So I was thinking I will grab a used transfer case and rebuild it.
Maybe I will wait for a 24t np271 to pop up, but seems unlikely.
Thanks again!
Leaving the hubs locked doesn't blow your transfer case, if that was true every 4x4 Ram HD made from 2002-2012 would have a blown transfer case since they all have full time hubs.

I’m still not sure what input shaft you are referring to. In any case, on a tcase cracked open like that all the internal components are now suspect.

You’re right. It doesn’t. An unbalanced driveshaft getting spun does.

What fluid did you put in the t-case?
Your ZF6 t-case has a different input shaft than 4R100’s have. (It’s the same as 5R110 *I think*. Swapping the input shaft and resealing the t-case isn’t that difficult if you don’t find the correct t-case.

Thank you. I wasn’t sure what he was getting at since I’m a 4R100 guy.
For your viewing pleasure and reference value, I have attached the transfer case assembly and disassembly, removal and installation instructions according to Ford.
It looks like you have a new TC acquisition course of action set out already, but if you need to purchase a refurbished TC, All Star is a good source for that sort of thing. Link: https://www.allstarstandardtransmission.com/
