ok, so WTF is this?
 

I finally drug the mystery axle that was left in my yard when I moved in around to the front of the garage (that fugger is heavy). I even took some photos of it. Can someone help me identify it???

It has an 8-lug bolt pattern & 8 little bolts in the hub. The (SUA) spring perches are angled to the side. The diff cover has 10 bolts in 2 different sizes.

OLD MILITARY ROCKWELL AXLE? :confused:

It looks like photos #8 & #9 on this page:

What does that mean it is???

An old eaton rear axle maybe. Expensive and maybe more difficult to find parts on. I'll bet the ratio is low!

hit it with the sand blaster and see whats inside

Looks to me like a 60's GM Eaton axle

Yup looks like a eaton. Pretty strong but very hard to find parts for.

eaton, worth about it's weight in scrap... unless you have the matching front.

It's an old Eaton axle out of an 60-70's era Chevy/GM pickup that used the trailing arm style suspension.

They are generally known to be pretty stout and often come with 4.56 or 5.13 gears, and sometimes a Detroit. I've seen lots of guys running these in fullsize trucks with no issues. But as already mentioned it's getting pretty hard to find parts for.

Not quite sure what the "unless you have the matching front" comment means??? It should be a fairly common width and standard 8-lug pattern which matches just about any 8-lug front axle, not like it has a funky bolt pattern like some of the old military axles.

so what are you going to do with the axle now that you know what it is?

It can come and join all my axle at my house lol

thought it was a funky ratio.

Not sure what I'l ldo with it, I want to clean it up & look inside & see if all is ok or not. It has been sitting outside for a few years, so all may not be well.

the track bar mount-looking thing and angled "perches" prolly mean it was froma coil-equipped c20. i wouldnt scrap it-it may well be worth something to someone with that era truck. 67-72 era trucks and parts are certainly getting harder to find.

what ever happened with this? did you open it up?

While Were On The Subject Of Mystery Axles Ive Got One For Yall. Rght Now Its On A Small Boat Trailer I Have. Its Only About 4' Wide At Most (and Shows No Signs Of Being Shortened), Has A Square Diff Housing, The Axle Shafts Are Threaded On The OUTER Ends With A Keyway And Use A Crown Nut And Cotter Pin To Hold The Hub On, 4lug, And 12" Rims. Aint Got No Pics Of It At The Moment But Can Take Some If Anyone Might Have A Guess.

Tractor axle

never thought of that, quite possible now that i think about it.

I know a guy that runs them (Eatons) in truck pulling, he said he tears up 14 bolts and the eaton just keeps digging. Let me know if you are going to dump it and I will ask what he will pay for one.
