The item shown in the listing appears to be the same as the OEM. However, they did not send me the product shown in the photo. Anyway, I installed it and it worked. The ball joint does not have a castellated nut. It's a critical suspension component, so it's a bit of a concern. I'm still trying to figure out how to fix this. Maybe a self-assured mother. Maybe I'll drill a hole. I do not know. This is an awkward position and would not have happened if the listing had been honest.
