I've been laying in the garage working on my first mod -- replacing my 2.73's with 4.10's. This has been my bible: http://www.superstallions.com/tech/drive/gears/gears.html I'm stuck on #15 though: (removing the pinion gear) I assume that means to hit the side of the pinion gear towards the front of the car (that the nut goes on) and drive it back. It looks like the flange is just held on by friction. I'm hammering, prying, soaking in oil, and doing everything else I can think of, but it's not coming off. Do I have the right idea? Is there some trick? All I can think is to go buy a 6 foot breaker bar or get the sledge hammer out. Thanks for any help!
