I was reading on Dodgeram.org and it seems that they list 2 different fluid capacities for Dana 80 axles..
Axles found on 2WD trucks have less fluid capacity.. Is this true, and if so, why would it make any difference?

Seems like more hassle, keeping track of 2WD & 4WD axles.

I bought a Dana 80 out of a 2WD truck.. Should I be worried about the decreased fluid capacity?

 

I've never heard of that, better cooling possibly with more fluid?

 

Thats definately the concept, but why have lower fluid capacity for a 2WD truck?

 

either way there is a TON of fluid in there...mine (4x4 dana 80) took 5 quarts...

 

Lube Capacity
4x2 6.8 pints ( 3.22 L ) 3.4 Quarts
4x4 10.1 pints ( 4.79 L ) 5.05 Quarts

 

Why not just fill it up and go on?

 

I would say taht regardless of the fluid capacity, get yourself some thicker weight gear oil, IE 150W or so and u dont have to worry much about heat. I know that my recent rear end oil change took 5 quarts of synthetic oil, but my mpg has improved by at least 1 mpg, my truck is a 4wd with the dana 80 rear end.

my guess would be that the 2wd is lesser duty axle or maybe a 180 pump truck? Im not completely sure... But i dont see why they should differ..

I'll throw it on tomorrow, I'll post pics!

 

Because I'm good at breaking stuff, and I'm curious if its that important that there will be less fluid
