So, in keeping with what I said in a previous statement, I will be the first to admit when I do something bone headed. And that includes posting information that isn't correct. so to make a long story short, I will apologize to the ones involved. I know this is the internet and it may not matter that much, but I do pride myself on making statements I know that are true and will hopefully help the ones that are reading them. After conferring with my fellow employee at our shop, he was indeed talking about enlarging the inner pinion bearing race to make setting up pinion depth easier without the tools. I misunderstood what he said as I only came in on part of the conversation and didn't question what he said due to the fact that he does most of the drivetrain work at out shop. So to the ones that were involved in the original post I do apologize. Happy Fourth of July !!!!!
