I have a 1996 CCLB F350 7.3 and I thought I had Dana 60's front and rear, a buddy of mine said the rear looks like a 70. I don't know much about axles, how would I go about identifying what exactly I have under the truck?:confused:

You have a Dana 60 in the front and a 10.25 Sterling in the rear as long as it isn't a dully.

The rear tag should be 3L55 which im pretty sure it means you have a limited slip

Just like Bugman said: Dana 60 front.....if it's SRW it's a Sterling 10.5" rear and if it's the DRW its the Dana 80 rear
It is a Sterling 10.25 if it is a SRW, they switched to the 10.5 in the SD

She's a SRW, Now how did you figure this stuff out based on the numbers I posted. I'm curious to what numbers mean what.
It is just what axles these trucks use. They all had the 10.25 rear and F350's had a D60 front and F250's had a LD or HD D50 TTB front.

CFiss, here's how to decode your rear axle tag:
It reads "L55 10 2 6A25"
As someone mentioned, it should read "3L55 10 2 6A25"
The first number is usually under the head of the attaching bolt.
That means 3.55 gear ratio with traction loc-- "3L55"
If it were an open diff it would be tagged "3 55"
It a 10 1/4" ring gear-- "10 2"
It was made January 25, 1996-- "6A25"

Awesome, thats the kinda stuff I like to learn about trucks is how to read a partnumber and not just see letters and numbers, now what can you tell me about the front axle tag? Thank You by the way for taking time to explain it!
