dust/hot engine compartment air seal and white plastic retainer from the factory.

You can add a bearing there if you want. I did this mod on mine and it was pretty easy since I was redoing the steering joint anyway. Pin has to come out and I had to do a little sanding on the shaft and grinding on the bearing to get it to slide on. Here is the how to and part number, got mine from amazon.
