I'm needing to replace some ujoints and I'm told that my front pinion bearing on my rear axle (10 bolt) needs to be replaced. How straight forward is this. What I've been told is to drop the drive shaft, take the nut off the yoke, pull the yoke and I should be able to take the bearing out from there, is this right? Also when I go to replace it the bearing, what parts do I need to buy, the bearing, spacer, what else? thanks
