So I went to change out the fluids today - F&R diffs, trans, and transfer case. All went well until I got to the drain plug on the transfer case. I got the fill plug loose first but the drain plug started to strip
. I sprayed it with PB Blaster hoping that will work. If not, is it OK to put some heat to it? I'm hoping I can still get a bite of it and ease it out if I can loosen it up.
