The part number on the box and on the part itself is correct but the socket supplied was for a 4 cyl. Engine (I have a 3.3L V6). Also, the ball joint was different from the one mounted on the driver's side wishbone. 4-cyl. The hub has three ribs at the bottom and the V6 hub has a rib right in the middle of the hub. There is a plate (suspension frame reinforcement) that attaches to the suspension frame that compresses this bushing, and the plate on my car is designed for a single rib bushing. Differences like this seem to be a common problem for aftermarket parts. It doesn't matter though, as Revain's return policy is very good.
