    Is there supposed to be two bearings, a large and small one on the pinion? I ask this because there is a small opening inside the case where the pinion stabs into next to the ring gear that looks like it should have a bearing for the pinoin to ride in.

    Who said size doesn't matter?

    yes, there is supposed to be a bearing in the housing near the ring gear for the pinion bearing, this would be called a pinion support bearing. there are also the other two bearings in the pinion support that comes out of the housing.

    I appreciate the info.
    So is the bearing actually bearings like the rest of the pinion bearings but just a smaller set or is it like a pilot bearing similar to what is in the end of a crankshaft?

    The bearing is similiar to the other pinion bearings with the exception that the bearing rollers are not tapered like the others.

    OK, Thanks for your help. The reason I didn't know what type of bearing or even if any was used was, All my pinion bearings went out and when I pulled it down to change the chewed up gears, there wasn't a bearing in the housing for the pinion. I guess that's the bearings and bearing cage that I pulled out of the bottom of the case. Thanks again...
