Question about rear differential

[burbboysgc]

 I have a 14bolt F.F. rear. My problem is my gear oil filler bolt is stuck. I have used penetrating oil, and have still have broken 2 ratchets, and a breaker bar. Is it possible to put gear oil in the spot where the breather hose connects at the top of the housing?

I would keep trying, get a quality breaker bar with a warranty. maybe you can use an impact wrench.

Maybe apply a "little" heat to the surrounding area?

heat it up and touch a wax candle too it. the heat lets the wax get into the threads and let them slide past each other as long as they are pipe thread

Thanks,for the advice. I persuaded it to come out with a couple whacks with a 3lb hammer and some Pb blaster.

     They make a product called "freeze" it is in a areasol can that looks like wd40 or pb brake.  If you first use that, then heat it, most always you can get rusted things apart.  I use it at work all the time with much success.
