Just like it says. What diff is in an 01 2500 Diesel 2wd?? Is it the Dana 80?? Is it the same as a Ford??? Thanks. Aaron

 

Is it an auto? If so it should be a Dana 70.

 

Stick 80, Auto 70

 

Fords run Sterling 10.25 in the 97 and older trucks, 10.5 in the super duties. The F-Super Duties had D80's, but were 37 spline (dodge is 35) and was a 10 lug. Spindles were different, so swapping hubs to go to 8 lug isn't a viable option.
