Steering columns will really mess with you. Just a thought, but many of the columns, the top part anyway where Chevy.
I had the bearing your talking about (I think) come apart on me once, after hunting for all the pieces for about an hour and finding the last bearing stuck in the bottom of my shoe. I put the whole thing back together again, pressed the little tabs and it worked fine.
Was your steering wheel kinda wobbly?
I know for sure many (most, all) of the YJ´s with tilt steering were Chevy columns. Look at a blow up somewhere, of the Chevy column and compare. The part you need might be a close as the nearest GM dealer and cheaper.[addsig]
