Differential Flush Question (not a fluid Q)

[Lupercal]

So I was all prep'd to change the fluid in the diff, got my fluid, a little pump, a 3/8" extension. But man that bolt did not want to come out on the bottom. Is there a trick to this or do I just need to borrow some muscles?!

You may try doing this right after a long drive.
The plug will probably be able to be loosened easier if the cover is hot.
Aluminum will expand more than steel when it is warmed.

Thanks, i'll give that a shot along with a breaker bar.
