OE ix ball joint its not all metal. I should taken pictures when i complete disassembled them. as another member described, The xi outer ball joint is surrounded by a rubber damping sleeve which in turn is captured by the outer casing and a bottom cap. Even the base where the actual "round ball" sits in its plastic. Please disassemble one before "chiming" in. it bottom base just looks like that on the outside so it makes it harder to press out. the ball joint you posted its an HD version of the same ball joint. which i didn't feel like going for them when i found out that they sat in plastic.
Now how long they will last for, we live to see.
On another note, ill be doing the alignment today and will post results later on today.
