Ok here goes the book Im about to write.
I bought a 02 raptor 660 and the rear end was squeaking very bad. I took out the rear axle and noticed that the bearings in the rear are all tore up, there are only about 10 balls rolling around throughout the whole casing. Yes, you are right they are not in the bearing housing but in the center. I hear a lot about carrier bearings and Im wondering if the bearings that I am replacing are the carrier bearings or if there in another inside the housing because there is a small pipe inside the housing. The balls have wedged in the center where that pipe is and made grooves in it. Will this be OK to just replace the bearings and seals and ignore the groves on the inside around the pipe? Also, does anyone have any advice on how to pull these bearings and seals out of this because it is pretty bad, there was not even the center metal left on the bearings.
