Obviously, the geometry has to be different on the left and right lower ball joints. But, I was surprised to see the different machining and dust covers on the two. The RH side has a much larger nest for the ball, a differently machined shoulder, and a different style dust cover. These are Moog parts (K783 LH and K781 RH). Is there a reason they are designed differently, or was it likely just a production thing in Moog?
