Well how about that, thanks everyone! Now i know I have a dana 44 and where the springs in my diff cover came from. Glad I joined this forum. One more question though. I've had an impact gun, pb blaster, and a hefty breaker bar on the front pinion nut trying to break it loose (because it is leaky too). It hasn't budged. Any helpful tips beside persistence with more pb blaster and impact gun to get it off?
