Are these parts used? If so, I would shy away. You can buy new ones at a fairly decent price and you don't have to worry about any issues you may have from the new ones!

It might be good to know what happened to the car they came off of. If it was front end accident they might be bent. The Hubs are the most expensive part of the front end.
