Thanks for the insult Noobz!
I installed the gears on my car myself. I do all of the work on my vehicles myself.
Once when I was a younger and and less experienced man, I had to take my car to a shop a couple of times because I was stumped and just could not find the problem. After these shops struggled to find the problems themselves and then charged me an arm and a leg for their wasted time, I decided that I would never take any of my vehicles to a shop again.
I did not intend my general statement about replacing gears to be considered a "how to", so yes there were some things that I did not mention. SO... Let me revise my previous post.. As with almost any work on a car, you will need some instructions and some tools... Also, for this job you will need some specialty tools (most of which can be rented from an auto parts store)... You will need to have the new pinion bearing pressed on. You don't need to replace every bearing, race, or seal that you come across, just replace it if it's bad. Yes, it is a good idea to replace it if you have it apart, but that can also get expensive and we are talking about bang for the buck here and not talking about how much money we can throw at a project.
Oh and this is not meant as an insult it's meant as a challenge.
It's for anyone who would like to create a step by step shade-tree version of doing this task at home.

ronstang94... Don't take it personal. You'll find that I'm all over the forum and sometimes make quick posts to illustrate a point without fully explaining that point. Many people come to this site looking for answers. I didn't want anyone to get the impression that gears was a quick-fix kind of thing like swapping an intake or adding a CAI. I would guess that even a quarter of professional shops, screw this procedure up from time to time.
