Axle Diameter on Dana 60?

Postby ryanihf250 » Mon Aug 13, 2007 5:11 pm

I have a 92 D350 with the Dana 60 I suppose. I found a 60 on the front axle, but how do I definatley tell? I need the axle dia. to order some ladder bars. I want some L&L ladder bars but they have the axle diameter. I am trying to order them from National Tire and Wheel. I measured myself and it was 11in around the back axle tube. The salesman said that there was no way, so i guess i am a dummy and can't measure it right. He said that he thinks that it should have a 3 1/2in axle diameter on the 60.
Thanks for any help

Your truck should have a 70 axle under the rear. If it has a 60 someone put it there Dodge didn't.

The measurement they need is the dia of tube is not the outside radis.

I can throw a tape on mine tomorrow for you.

You guys and your geometry wow!! Quick lesson on circles.
Circumfrence = distance around
Diameter is distance across
Radius is from the center out or half the diameter
Circumfrence divided by PI or 3.141592654 = Diameter
That means your 11" circumfrence axle is 3.5" Diameter :P
