I was at the junkyard today and saw an old chevy van, '72 I think. Anyway it was a 1-ton and I saw that it had the Eaton rearend. Are these things any good? What would one be worth? The yard wants $89 for it.

Anyone using Eaton rearends?

They're probably worth the same as a 14 bolt.
They have coarse spline (16?) axle shafts, most had low gears (4.56) and many had factory detroits.
The 14 bolt detroit and shafts are a direct swap, clearance might be a little better on the Eaton. Replacement bearings/parts are fairly expensive.
The housing is steel and hence you can weld to it (great it you plan on linking it) and it has a drop out third member.

19 spline.
If the axle is in good serviceable shape it's generally considered a sound piece. As he said though replacement parts are hard to find and generally not cheap.
Trying to remember who but there was a guy on here and Pirate who had one of the tricked out Eatons with the 14FF parts in it.

I run them, and think they are the best diff out there for light duty stuff,,,,,,,,,,,,,,,anything under three ton. They were used from 3/4 to 3 ton trucks. For gear ratio's 4.10 , 4.56 , and 5.13 are about your only choices. I shaved the bottom of one of mine and now have more ground clearance than with a 12 bolt.
Has anybody disc'd one?
I am assuming the strength is comparable to a 14BFF...???
The drop-out 3rd member intrigues me...

I *think* I saw that the disc brake brackets for a FF14 bolt also work on an Eaton.
Strength is probably comparable but IMO the 30 spline shaft and locker upgrade is worth it unless the Eaton already had a Detroit.
Yup, put rear discs on it, and machined the hubs and redrilled for 6 bolt. The 14 bolt was the replacement for the eaton, as they felt they didn't need a diff that strong. I'ld post pics,,,,,,,,,but I don't have access to post pics.

Ive been running an Eaton in my truck for 16 years and agree its the best light duty (under 3 ton) rear out there.
Its brutally strong and has better ground clearance than a 14 bolt.
The drop out center section is a nice bonus. I have a 4.10 4.57 and a 5.13 centers. Just in case I want to go bigger.
Standard 14 bolt ff disc brackets work.

Ok i gotta stop reading this thread. The more I read, the more I want to go back to the junkyard and buy another axle I don't need

Buy it!!
wait now 6 bolt hubs!?!?!?!? I must know how that was done!
That's actually a 6-Bolt full floater?
You have to machine the hubs down (making them thinner, questionably safe IMO depending on how much needs to be removed) to allow 6 lug wheels to fit over the hub, weld up the 8 holes for the wheel studs and redrill the hub for the 8 bolt pattern.
Yup I did machine it down. The only questionable area is where the snap ring goes. Then I just redrilled for 6 bolt. No need to weld up the 8 holes. I made three of them when I did it, just in case I broke on the trail. I've beat on it pretty good, pulled a 12000lb trailer, and so far,,,,,,,,touch wood,,,,,,, its worked well. I did it cause I had a locker for an eaton, and my mags are six bolt. I also kinda like the sleeper look. Six bolt wheels, its gota be a 10 or 12 bolt

I have at least two sitting around.
God axles.
My money says they're lighter than a 14. Dropout third AND a removable cover in the back.
