Need some help with carrier bearing

[davepl]

The replacement carrier bearing assembly I'm about to install is a little different (primarily cosmetically, I think its the right one) than the one I removed, and it's different enough from the one in the shop manual that I can't entirely rely on it to get it back in the right way. Translation: it looked simple enough when I took it apart a couple of months ago, and I should have taken better notes.

Anyway, the picture is below. My main questions are:

1) The way I've laid it out, is the carrier facing the right way? It has a steel dust shield on one side, the old one had rubber on both, so I don't know which way it should face.

2) The little "ring" in the picture... what is it and where does it go? It doesn't slide onto the splined section, at least without being seriously pressed into place. I have no idea what it actually is.

3) Am I missing any rubber seals? The shop manual mentions and shows rubber seals, but maybe they're already inside the assembled carrier?

4) Why does the end of the yoke have a screwcap on it? Just to hold grease in? Do I slide the yoke on with the cap already screwed onto the yoke, or is there more to it?

Thanks!
