I have never had any Dana bigger than a 60. They were okay on a 3/4 ton truck.
Here is what you can tell them:
1) The r60 axle housing is structurally stronger than any Dana 60 out there, and I suspect stronger than the Dana 70 and 80 also. Why? Because it is a formed housing - basically a one-piece housing from spindle to spindle once it is built. The Dana is constructed from with a strong center section with pressed in and welded tubes to house the axle shafts. Those welded joints, and the tubes, are the weak point and the reason the aftermarket jumped on the opportunity to make all of those axle trusses to fit all of those Dana equipped trucks back in the 70's and 80's. Have you ever seen a r60 bent? Me neither. But I have seen Danas that were bent.
2) The r60 has three roller bearings supporting the pinion gear, an adjustable thrust pad backing up the ring gear, and no crush sleeve between pinion bearings. In fact, the pinion was not made to be adjustable - just the ring. Right in the manuals it instructs us to try another gear set if the tooth contact cannot be achieved by adjusting the ring gear.
3) The r60 has a four pinion differential.
4) I think some Dana 60 axles were semi-floaters. All Dodge r60 axles were full floaters.
5) The Dodge r60 was designed in-house at Chrysler. Not just some off-the-shelf tag on from a preferred vendor.
If this does not get them stirred up on face book, it should at least get someone stirred up here on the forum.
