The truck is a 88 f250, it looks like a D60F due to the center section kIng pins, 1.5" shafts, warn hubs instead or spicer but here's the weird part, it has a 351, 2 leaves in the spring pack, a sterling rear and the spines on the inner shafts have been cut off same with the pinion gear. So WTF? I'm thinking this may be a D50? D61? I can email pics

All these Ford versions were drivers side differential, reverse-cut (high pinion) gears, and kingpin knuckles to 1991.5 and balljoints thereafter. Most Ford D60s are internal style hubs, but external type lockout versions do exist. 2000 and later Ford D60s have balljoints, a metric wheel lug pattern of 8x170mm up to F350 and 8x220mm for F450/F550, different brakes and spindles, sealed "unit-bearing hubs", hub-centric wheels, different length axleshafts from the earlier D60s, and larger Superduty specific tie rod ends. From 2000 on, the Ford D60 front axle is also known as the Model 60F2000+ or the 248M. 248 just happens to be the equivalent in millimeters of 9.75" - the diameter of the D60s ring gear.

I'd say Dana 50 - but the KP throws me off.

Right, that's the thing, it has 60 KP, hubs similar to GM but with piston calipers. The carrier & ring gears are missing. send me an em to joe@spgreo.com and i'Ll send u pics of the cut shafts and pinion.

2 leaf is stock 250 or 350 springs, no biggie there. It is supposed to have Warn hubs, the Spicer hubs were only on the 70s ford trucks. Sterling rear is right, and if its a monobeam kingpin axle, its gotta be a 86-91.5 ford D60 as the older ones wouldnt bolt into an '88 due to the different spring pad width.

All that said, it should be a D50 TTB, but obviously its not if its kingpin, and we all know how easy it is to swap a D60 into a F250 of that vintage.

You are implying the carrier is gone.....are the bearing caps still there?

that makes good sense, the carrier is gone as well as the bearing caps.

if it has king pins, it's definitely a HP60. look around for the bearing caps...maybe the jackass who pulled the carrier left the caps laying in the dirt somewhere. I would still grab it for the right price though. get some replacement caps and go with it.

I had always heard that if the bearing caps where gone it rendered the housing worthless, perhaps I was led astray? Please enlighten me.

It's not great for it to use different caps or switch them around. but the only thing that it will really cause is your carrier bearings to wear out a little faster. I'd still run any axle with different caps. I would just be expecting to replace the bearings after a while if I ran it on the street.

correct. it's a front axle and it's not likely to see a lot of highway miles with the hubs locked. if it's a really big concern, find an axle shop who can line-hone the bores with the replacement caps. cost might be high which is why most wouldn't worry about it.

Thanks for the info guys.

So, Joe V, did you find the bearing caps and get the axle?
