Stuck on gear install (help needed)

  1. 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:

    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!
  2. Take the pinion nut you just took off, and thread it back on the pinon till it is almost flush with the end of the threads. Almost like the nut is sticking out only a thread or so off the pinion gear. Then hit it with a sledge hammer. This way you don't damage the threads on the pinion gear coming out, and the pinion doesn't go flying out of the back of the carrier.


  3. What I found to work fairly well was to use a pulley puller to get the flange off first. Once I had the flange off the pinion drove out fairly easy.
  4. Thanks guys! I went ape with the sledge hammer and it eventually popped out.

    Now I'm off to AutoZone to try to rent a bearing puller.

    The wife keeps telling me I should have just hired this done. My response is that I'll do that once I get it all back together and it whines and squeaks like crazy :D
