not really but sorta, my freind and I were changing the fluids on the car today, I had the tranny and he had the dif, he started draining it and then whent to open the fill to help it drain (their was the mistake) sure enough the fill plug on the diff is seized in their, I tried pb blaster, I tried heating it up with a torch, nothing, I can't get an impact up their becasue I don't have a swivil bit, but still..any one have any sugestions other than droping the dif? I don't want to drive it any where since their is no fluid in it now....sigh I hate this crap.....
