Dif is shot, options?

Ok, had a clunking noise, sent it to a shop, dif is shot. Teeth broken off of gears, shop guy said it ate up the carrier unit. When i asked him if he ment the limited slip unit, he said yeah. so yall can interpret that.

Here's what I'm wondering and what I'm considering.

replace internals. will I need all new bearings? will I just need the ring and pinion if I'm ok with it being an open dif?

replace with a used axle. im not to sure on this... what if i get catastrophic failure again? what are the pro's and con's of this?

replace with a 11.25 rear. Is the dually rear that much stronger than the srw rear? is it the same width from hub mount to hub mount? can I use my axle shafts and hubs and all the stuff off of my 10.50 rear? what other modifications would i need? would the yolks and u joints match up? could I use a dually yolk set if they didnt or are the driveshaft bigger?

I don't know what I could have dont to prevent this... it was fine one day, then done the next. Sucks I just bought the truck too, havent even made the first payment

What should I do?

Personally, I would go to a junkyard and pick up a new one. Just be sure to crack the pumpkin there and inspect it. (Most won't take returns.)

If you have the tools/knowledge how to rebuild it, that wouldn't be too bad, but I bet it would cost an arm and a leg to pay a shop to do it.

Chitty luck man.... good luck either way. Was that the clunk you were refering to?

Yeah, tooth broke off and tore it up. You think I should go with a 10.5 replacement or a 11.25 replacement? I don't want this chit to break again. I'm probably gonna have a shop do it just so I don't have to be liable for it.

I'd just get another 10.5, why go through the hastle of the upgrade when the end result is pretty much the same, haven't heard of the pumpkins goin bad on these things too often. I know there was a couple of them at the junk yard where I picked up my leaf springs.

One of the one's through that car-part.com I showed ya? And that what I was thinking. Actually I had NEVER heard of it happening before my truck gave up the ghost back there.

You're welcome!

I do as often as possible, it's a great resource!

I don't know why that is... we tend to use the "same" parts, Ford must always use the better quality ones though. Just like the Ford zf6 is 100x better than the chebby zf6.... lol

These things dont go out that easy. I would just find a stock replacement be it from a doner truck or a pull a part.

Got a LSD, from an 80k mile 1 ton that didnt even have a hitch on it. hopefully this swap goes off without a hitch.
