Differentials Questions

I have a Dana 50 front end on a 97 F-250 7.3L. It only has a fill plug. Do I have to suck the fluid out or somehow take the cover off? How much and what kind of fluid goes in it? What kind and how much goes in the rear?

75w140 in the rear. It will take a little under 4 quarts. Just keep pouring fluid in until the fill hole starts spitting it back out. Make sure to use an anti-friction additive if you've got a LS differential.

Dana 50 ttb front end , suck it out, don't loosen the front bolts or you may end up with a leak you can't stop without taking it all apart. Same oil as the rear end but don't need the friction modifier.
