My 14 bolt FF has a pinion seal leak and I'm trying to get the nut off. I have a 1/2" thick steel rod that I drilled 2 holes in it and bolted it to the yoke so it wont move. Then I put the breaker bar on the socket and then on the nut. I put the jack underneath that breakerbar and jacked it up until the truck almost started coming off the ground. Then "pop", the breaker bar breaks. Tried it again with a 1/2" drive ratchet and it broke that as well. Why isnt this sucker coming off? I had this axle installed/rebuilt by a shop about a year ago. Any ideas? Tips? Secrets?
