Exclamation Cant Get Differential Fill plug off

Ok, the fill plug looks like it might be rusted on. What are some options on getting it off?

What he said.....The best stuff ever.
Spray, wait a couple min.
Tap with a ball peen a couple times.
Spray again.
Wait 5 min and remove plug.

I don't ever have to break out the torch since this stuff came around.

I found it easier without the use of an extension...jes got a 3/8" wrench, and put the end in there...I had to presss the button to get it in there, otherwise it wouldnt get in there all the way.

What he said, then just use a "cheater bar" on the end of your 3/8" wrench. Or if you have a breaker bar with a 3/8" end to it that would work well too. Pop the end in and give a good yank. Actually I did the same thing on the drain plug for my tranny but it was so tight that I had to position myself under it and just give the wrench a good kick to get it broken loose.
