8 3/4 vs Dana 60

I just called Randy's Ring & Pinion and they said the "green bearing" is not for heavy truck use or heavy side load use like road or circle track racing. They said it will wear out much quicker in that kind of application. The reason you have to use the "green bearing" on the Yukon axle is because it is shorter than the stock axle and is not long enough to reach the buttons in the center section with a standard tapered bearing. If the axle was the standard length you could have used the tapered bearing.
