Changing a bunch of suspension parts on wife's 07 Sonata. It's been a while since I've used Rock Auto. I decided to go with Moog parts which included 2 lower ball joints. Both came in Moog packaging but one is some other generic brand. One looks like a Moog ball joint with castle nut and whole in the threading for a cotter pin. It also has the greasable fitting. The other a rougher looking casting, a completely different animal with one of those nuts that have plastic in them for locking (are they called plastic locknuts? not sure) and no grease fitting . The writing on the top flat part says "Central Corporation" made in Korea. Seems strange I would get this instead of the Moog, what gives? Anyhow sending it back for refund. I realize Moog is not necessarily made in the US, but that's not my complaint here.
