Is the front diff interchangeable between all years 02-07? What about between gas and diesel? I know the mounting is different between the two, but does the Dana swap?

Yes the D30A's are all the same from '02-'07.The mounts and CV's are different for the different models.

Sweet. Thanks. I picked up a used front diff with 3.73s that I'd like to put a DTT in and have the gears set up, then toss it in my front end. What should I refresh as long as I have the thing out? Bearings? Seals? It's got 80k on it.
