I finally finished my diff oil changes yesterday after getting the rear and transfer case done a few weeks back, but getting stopped by a frozen front diff plug.:nono: I tried soaking it in PB Blaster, whacking it with a hammer, etc, but no matter what it felt like I was sure to strip out the hex if I applied enough force to break it loose, so I decided to order a replacement before proceeding. Once I had a replacement I had the confidence to mangle it if necessary to get it out. I tried what others had suggested and used a sharp chisel around the perimeter to try to loosen it, but that did not work, other than taking chunks of metal off and reducing the diameter of the plug. Finally, I busted out a map gas torch and heated it until oil was actually bubbling out under the crush washer. Then I was finally able to easily crack it loose with the hex bit! After that it was smooth sailing! Fortunately, the fill plug was very easy to remove (I made sure of that before trying to remove the drain, of course).
