I've seen a couple people complain about issues like this with the all balls steering neck bearings.
I used them and it is silky smooth, I'm not sure what I did different than the rest of you.
when I installed them, I over torqued them(slightly) then loosened them. I did this a few times then torqued them to spec. This ensures all the slack is taken out of them, and will make sure they are tight and not sloppy.
The tapered roller bearings should actually be a little more forgiving than the stock ball bearings(larger contact area to spread the load).
What do you mean by it makes an "s"?
