    Hey all
    Today I was in the boonies on a service call.
    This axle is outside next to a barn.
    It is an 8 lug full floating design. it has a third member(drop out) and a removeable rear cover. And a torque arm on the right tube.
    What is this? I have never seen one of these.
    It is a rear axle.

    Sounds a bit like a old Eaton from 60's very early 70's but really ahve toi look at it. Might even be a 1.5 ton axle. Did it have a big like big 14 bolt sized pumpkin?

    If it's a real big round cover with 10 bolts holding it on, it is most likely the Eaton. Used in 3/4 and 1 ton GM trucks from the 40s through about 1970 or so.

    I agree with the others that it is an Eaton.... I called my local rearend place and they said they can only get bearings for those and the third member.. Other than that, they said they cant find anyone who carries the parts for them.

    The pumpkin is big like a 14ff. the cover is round and has about 10 bolts holding it on.
    If parts were available, I would probebly go back out and try to get it.
    Thanx.
    See ya

    There is a company that is making gears for those Eaton rear ends again. I think Randy's Ring and Pinion sells them. Some of them had factory installed Detroit Lockers, although the Detroit is no longer available new.

    Does this thing look like a Ford 9-inch on steroids with a removable, circular rear cover?? My @$$hole neighbor occasionally has an early El Camino on a 4x4 frame (with 44's) in his driveway, and that sounds like the rearend this thing has under it.
