Default Exploded IFS! pics

It all started by helping someone that was stuck in a mud hole. I had the confidence in pulling him out.
After a couple of attempts in 4lo rear locked, in a slippery snowy surface... Someone noticed a puddle of oil.
Was still powering the rear wheels UNTIL i pulled back onto pavement and decided to pull it out of 4HI locked to 4HI. Then all of a sudden it would not power any wheels! Tried 4LO locked and reverse. Nothing at all. Had to be towed home.
Bought a front diff from an 04 2500HD and is totally different than my front case!
Im still in need of a good used front diff case...
heres some pics:

I've never seen a front diff break like that on an H2. Did it come down on a rock or hard object?

I wouldn't say it happens a lot...this is the first I've heard of it (and I cruise several different forums); but I'm sure it has happened before. Just as I'm sure it's happened on other brands of trucks...
...they might look like tanks; but they're not. LOL...they're just a truck.

Wow...that sucker can get expensive:

I'm betting he was at a high RPM in that snow and then it caught something to bite on...and BOOM!

the good news is.. it just looks like he needs a new housing. most likely can reuse alot of parts off his old one to help cut down on the costs.


whoknows, it might have been a defect in the housing.. i.e a hairline crack somewhere that just gave out when the right amount of force when he was pulling the other vehicle out.

those are pretty clean break lines on the housing...im assuming the vehicle is out of warrantry, but who knows... have it checked out. might get lucky.

traction 2 kept me down below 3500...
That sucker is very expensive.
I pulled a noob move and went to the salvage yard looking for a silverado 2500HD 9.25" diff. THEY DO NOT INTERCHANGE.
So i bought a whole new bare housing today and going to do 4.88's front and rear with possibly and E-Locker front...

Post back your results, especially if you go with a locker. I've been 'thinking' about it too.
