I am a little frustrated because my drain plug for the rear differential wont budge! I need to get this thing back on the road and I have done all the work that needs to be done but the drain plug is stubborn and I feel like its impossible!

Maybe tap it with a hammer after spraying some rust penetrant? The shock from the hammer usually helps dislodge stuck threads. Don't hit it so hard to deform it, just hard enough to send some shock in there.

Agree with DD, had the same problem, sprayed it with some PB'laster and let it soak and came right out.

IF your going to hit it. Find yourself a ratchet in your tool box (if thats the tool it uses) and smack the ratchet while you have pressure on it to turn it. Works for me every time. I have a old junker ratchet for just this use..
