06 Hummer H3 Front Diff Assy

[jphh20]

I am swapping out my front diff on my 06 H3 for another used assembly. My front diff breather hose pulled off and it filled up with water, mud and sand. I decided not to rebuild my original and swap out the assembly. My question is: how much is my front diff worth if I were to sell it as is to someone looking to rebuild a unit or am I better off scrapping it? I thought about rebuilding it but I would rather have a cast iron spare.

Drain it.
Pop the cover....have a look.
Flush it with mineral spirits and h.p. air.
Refill with fluid.
Run it.

Worth $300 in perfect condition. $10 for anything less than perfect.

lol............I love it $10 bucks! I would of done what 4 speed said and left it in there until it failed.

Thanks for the input. The front diff is toast. I was at rausch creek and the breather tube must pulled off when I was in some soupy mud and as we wheeled all day it filled up with silty water. I had no idea that this had happened until the drive home and 2 hours on the highway she started to growl. I quickly knew figured out what it was and after the 5 hour ride home the front diff was toast. Pulling the front diff cover confirmed what had happened. It's too far gone and a rebuild will far exceed what I can get a used replacement for. Hope to have the beast back in the road this week. I will plan to keep the diff cover and companion flange and will prob toss the carcass.

I might be interested in the carcass for a good price. I need to re-gear and this may be a good opportunity to do the work and have things ready to go.

Dammit, there you go. I've been flip flopping between 3.73 and 4.10s. A good used set of 4.10s and a donor front diff case may help make up my mind.

I have 4.10 gears from a front diff 75 plus shipping there yours.

This must be the first case of an H3 going for longer (lower numerical) gears!!!
