I've got a Dana 70 dually rearend and a Dana 44 front axle I am installing on an '83 Dodge pickup. The truck is in New Meadows at my brother's house, and I'm here in Nampa. Both axles need U-bolts, and I need some measurements taken so I can get some U-bolts made up before I go up to New Meadows this Friday. I need the inside width of the U-bolts, the shaft diameter, and the length. Any help I can get would REALLY be appreciated.

What are the axles off of? I have a Dana 70 dually rear out of a 79 Chevy that has 4 1/8" diameter axle tubes (no that isn't a typo, those things are HUGE), but I don't know what they would be on another year/make vehicle.

The Dana 70 was pulled from a mid to late 70s Dodge camper was what I was told. I tried to measure the axle tube, came up with 3 1/2 inches for mine.

The way I measured mine was to get a cloth tape measure (a.k.a. seamstress' tape measure), wrap it around the tube and divide by pi (3.141592.....).

Axle shound be 3 1/2" tubes. The u bolts are 9/16". As for length, dunno. The ones on my truck are like 16" :shocked:

This is on the D70 outta my 98 Ram 2500... I'm pretty sure the gassers are the same other than they have 35 spline shafts (diesels only got 32 spline)

Well, at the time I was measuring, I didn't have any calipers, but I did have a seamstress tape so...

That's not so bad right? Overcome adversities and all that. :idea:
