Just picked up a '88-'91 F350 (haven't confirmed year yet) dually. The passenger side of the rear axle is disassembled and missing the hub and axle shaft.

I haven't had a chance to see the truck in person, but trying to get parts so that I can put it back together and get it home.

From searching, I am assuming these trucks all had 10.25" rear axles. Is this correct?

The local junk yard has a pile of shafts, but needs to know the length. I have been searching the internet all day, but cannot find the length of the passenger side axle shaft on a dually. I can't even find a new replacement shaft for it.

Any help would be greatly appreciated!

 

it should have the 10.25 sterling rear end unless it got swapped out. i dont know for sure but in those years i believe the passenger side was the shorter of the two. oh yeah and make sure the axle shaft is from a fully floating rear end since yours is a HD model.

Had my dad go take a look at the truck for me. It is definately a 10.25. It has a 12 bolt cover with no fill plug. The hub and axle are nowhere to be found. Here is what I have found at the junkyards, all are 35 spline:

DRW Left:
41 1/8"

DRW Right:
37"
38.5"
39"

SRW Left:
37 3/4"

SRW Right:
35 3/8"

Of course the one I need is the only one with different lengths available.
