I went through the horror recently of replacing all my CV joints with new
ones---from china. At least they were free, that's the only good thing about
them. But they are still junk, so I have rebuilt my originals except the one
I had to replace altogether.
The chinese ones don't have any indication of direction, so they are no help
to look at. But the OEM ones have an embossed side of the center hub (a
raised area) and a flat side.

Which goes in/out?

Thanks,

Jim
