another dana 60 yoke question...

[DoubleDlover]

ok here a good one. Do the yokes on the mopar dana 60 take the U bolts that go through it and have the nuts on the back side to hold the universal in the saddles? Or do the bolts screw into the yoke and just use those U shaped straps thanks

The Mopar Dana 60 uses the steel straps with bolts to retain the u-joint cup....same as the 8 3/4" with the 7290 u-joint.

hi ther.e Yes it was starting to look liek that. So shouldnt i be able to get any yoke off a 8 3/4 diff with the strap type set up and it would be the same as the dana? I was thinkign yes. thanks

The splines are slightly different between an 8 3/4 yoke and a D60 yoke, they are both 29 spline but they do not interchange.

The Dana yoke will fit the 29-spline 8 3/4" but not vice-versa.

hi there. I was just thinkignthat. IS it possible to be able to describe why it will work that way but not the other way? thanks

[Scaregrabber]

I tried pounding an 8 3/4 yoke on a 60 and it went on maybe 1/2 inch and stalled. It was too tight to go on any further. It doesn't make any sense they made two different ones so close to the same but that's the way it is.

The diameter of both pinion shafts is pretty near the same (1.250") but the angle of the splines on the shaft is different. The 8 3/4" shaft has a sharper spline angle which allows the shaft to fit in the Dana yoke which has a less sharp spline angle.

Correction: (having a senior moment; I was thinking transmission shaft splines) The Dana shaft is about .015" larger, that's why the 8 3/4" yokes won't swap on.
