diff oil recommendation

Hello,
A friend has a 1994 F250 2x4 that needs the differential oil changed. What is recommended? I will probably pop the cap just to take a look for sludge build up and take a look at the gears.
Thanks,
Jcris

“pop the cap?”

Out of curiosity... what other way were you going to change the fluid if you didn’t remove the cover? Stick a tube in there and suck out whatever you could with a transfer pump?

From what I could see there is only a fill port so the cap has to come off to get it drained completely
