[HELP] Suggestions for 3 jaw chuck lubrication

[vtsteam]

I just installed a Shars 4-jaw on my lathe, and it's feeling a little rough even though new, I'm going to take that apart, and clean and lube it -- I'm assuming in that case just oil, no grease, since there's no gears or scroll. But I'm not confident it isn't a quality issue. Anyway, we'll do the best we can.
