    Universal joint for a Dana 44 of a 1951 Ford F1 Pickup

    Have just ordered a prop shaft to be made for our truck. The guy who's making it is having trouble with the measurements I gave him of the axle.

    The axle is a Dana 44, i.e. the standard axle that came off our year of truck. He had me measure the diameter of the end caps and the distance across where the end caps will go so that he can make up the universal joint.

    He has asked me to source the U bolts that would have gone with the axle, but has also told me that the diameter of end caps I gave him doesn't make sense.

    Basically I tried a pair of 27mm end caps and they were too big. So I offerred up some deap reach sockets in the gap and found that my 17mm socket fits excellently. The outer diameter of which is 26mm.

    Obviously, I realise that the axle would have been made to imperial measurements, for which the best measurement I can get is between an inch and about an inch and a sixteenth.

    Upon reporting this to him, he said that 26mm doesn't make sense, he doesn't know of any end caps that he could use.

    So two questions,

    Has anyone tried to marry up to one of these axles before, if so, what end caps did you use?

    Does anyone know where I can source the correct U bolts? and/or end caps?

    Unless some previous owner has butchered/remachined it, your Dana 44 yoke will almost certainly either be a 1310 or 1330 size on that truck.

    1310 is 3 1/4" between the retaining tabs on the yoke. 1330 is 3 5/8" between the tabs. Both use use 1 1/16" diameter bearings IIRC. Any US car parts supplier (here or in the US) should have the U bolts as they're a standard item.

    If your yoke is boogered, I have a spare new 1310 Dana yoke and U bolts here.

    I measured that gap to be 80.6cm, which is approx 3.175inch.

    I'm pretty sure the yoke would be standard and not messed with. Unfortunitely its a bit difficult to post pictures right now as we've just moved and dont have proper broadband at home yet.

    Is it difficult to remove a yoke without damaging anything or having trouble putting it back on?

    Am reluctant to take it off as we kinda painted over it and the retaining nut etc. and have read scarey stuff about needing specialist tools/knowledge to work on those axles.

    Not difficult to remove the yoke. I have removed/changed yokes on several axles without any problems. Undo the big nut and use a puller bolted through the yoke to pull it off the pinion with the forcing bolt. All the D44 axles I have had apart have a 26 spline pinion. Apparently some very early D44s are 10 spline, but I've never seen one.

    Refitting the existing yoke or fitting a different yoke to your axle shouldn't mess with the pinion preload or engagement settings. If you have a crush sleeve in your Dana, you won't change its setting unless you put more than 150 lb ft or so on the pinion nut when you retighten it (the crush sleeve needs a lot of force to get it to change shape and increase the pinion bearing preload -a 100 ft lb or so is plenty (with a drop of Loctite on the nut) to stop the yoke coming loose without affecting the crush sleeve setting.

    However, Most Dana's don't use a crush sleeve, they have shimmed preload for the pinion setting instead. The shims are nipped against the fore and aft pinion bearings by the pressure of the pinion nut on the yoke. This means that no amount of tightening (or overtightening come to that) when you remove and replace the yoke will change the pinion preload/engagement settings at all.

    If you want to see what's inside your D44, there's some pictures and info on rebuilding them here: Millpower-Race-Engineering scroll right down the page once you've clicked.
