how do i tell the difference in a dana 60 and a dana 70 rear end,,,,i have a chance to get one out of an 89 gasser 250 it looks just like mine..

 

It should be cast in the center section of the housing I think but a gasser would have a 60 unless someone swapped it out.

 

hey-Hey!!!,
The D70 has axles that look like nails and do not have wheel studs on them. the D60 axle actually carries the vehicle load and the D70 has a hub with tapered roller bearings. The D70 axle only carries drive torque( vehicle load is carried through the hub ).

I think you got things backwards there...

 

If you're a gambling man I sense a fundraising opportunity... But seriously, the D70 is the floating axle style, and the D60 axle carries drive torque and vehicle load.

There are full float D60's as well.

They are probably even semi-floating D70's out there somewhere, too. Dana sold axles to all sorts of manufacturers.

 

So this would have been a fund raising event for somebody other than me...
cheers,

i have owned a 86 w250 with a full floating dana 60 rear and an 87 d250 2wheeldrive with a regular ''what i call flat axle''dana 60 could that be what your thinking of,,would it tell you which axle on the door ,,or in the vin #

 

yup, 60 or 70 should be cast into one of the 'triangles' around the center section.
