On the left I received an open package. I bought this one correctly because the ball joint and markings on the arm looked the same as on the MOOG. They're within .2 pounds of each other, but Dorman's ball joint is really loose and weak. I didn't expect that for so much money. It's like a $35 gun in terms of the extras. All of the welds are the same as MOOG, only they lack the strength you would expect from a new ball joint.
