Gotchya I'll try the lower screws first to see if they drain it. But yeah it probably should be opened up and checked. But yeah I was debating if I should hook that up outta truck and hit the selector button to see if it clicks or whatever it does, to make sure I don't need to do anything else before installing. But one other thing I just noticed about this thread, nobody has said the best type of gear lube to put in the diff? I got the 20w engine oil for the selector motor...
