Yea, Pirate, mine had a bit of corrosion on them, like they had been sitting for a long time, it contributed to the not engaging part and the apparent lack of grease, but that's really only packing grease so taking them apart and packing some grease in there will definitely help (it's made mine work a little better) Here they are.
Little bit corroded, especially on the inner parts, may have to clean them up and then grease them good.
Also like I was talking about earlier, these don't appear to be Aisin hubs (I thought they were going to be) but some company named SHX, I assume just another copy cat company, we'll see how this shiny cast metal holds up...
I know Paul said that they come from some local place in Shanghai (??) that makes them, I guess I had assumed it was Aisin branded, or just a Mitsubishi manufacturing company. Ah well. Good price for sure! Thanks Paul! Just need some good cleaning and sanding.
