I am sort of looking for an old Eaton/GM drop out center 3/4 or 1 ton axle. 1 ton prefered (HO72). I really would need to find one with the 5.14 gear set to use it. Just starting to look and see how easy these are to find, or not. This may be kind of a long shot, but if anyone has any leads let me know. Not my pics, just found on web. Something like this:

Big O, I saw an eaton ( pickup) drop out on craigslist, within the last 2 weeks. BTW PM me for more info about the "NEW" snow wheeling route! Toyrocs

? What "NEW" project do you have planed for an Eaton? Those diffs are becoming rare & very little mods/ parts are available. Inquiring minds want to know! Toyrocs

The eaton's have some similar dimensions to a 14bolt which make them very interesting. They have a two piece carrier that has the same internal dimensions, so my welded spiders(or a 14bolt mini spool, or detroit) will drop in. Also the axle flanges are the standard bolt pattern and 14bolt shafts are the correct length.
It came from the factory with pretty low gears, one lower option being 5.14s. So I could build a rear axle that is a fair amount lighter and just as strong as the 14bolt. Cut and plate the bottom much more easily, truss the rear of the housing, weld link mounts directly to the top, etc. Only problem is parts availability.
If I can't find at least one with the right gears and possibly a second for a spare I'll just have to keep on with the 14bolt. It's treated me really well so far, and I have a spare already.

I was down at Six States yesterday & asked about the Eaton axles & parts your interested in ---- they said just a new pinion bearing alone was about $ 250 . The other parts ( carrier bearings, seals & such) are similarly priced (expensive).
The parts are becoming very rare & the ones that do show up are being used on classic "show trucks" . There are no new gears sets being MFG, so you would have to find a used set for your installation + any spares you may need. Toyrocs

Got the msg, thanks for the heads up.
It's starting to look like it may just be too much trouble to mess with. If I were running 4.56s this would be easy, but the 5.14 option gears seem to be really hard to come by.

Hey guys, thanks for keeping an eye out for one of these. At this point it looks like I'm going to stick with the 14bolt I have now. This project is already running behind and I don't have any extra time to try out my oddball ideas.
Although, next time I need to build up a pair of axles I may go with one of these eatons.

i have a stripped housing and four ten open third member. could probably find the axels hubs and bits too but..... they are tough as nails for sure.
the units that came with what i believe they called an eaton "no-spin" are the foshizzle. ive been looking for a next to free 4.56 or deeper no-spin unit for years. my buddy has a 2wd pu with an eaton but i dont know what the gears are. i have been waiting patiently and might have to give up something juicy if its what ive been seeking.

I think the 'no-spin' you are referring to is the detroit drop in locker. You can also use a 14bolt detroit and 14bolt axle shafts to get the same setup.

yea man, i was under the impression that the no-spin was the way they came fromt he factory and that all the carriers for the eatons were all open except for the ones that had the no spin internal locker. if you know the reel skinny im all ears about what interchanges ect. i have not personally tried this stuff but always wanting to learn.
i will call the magrimpkin master and ask again. im sure he has told me these things before but.... crs.

That's what I understood to be the case. Factory installed detroit. Just like the 14bolt, the detroit for these isn't a full case replacement, it goes in the open carrier.
