This is not a knock on Bill Rolik but when I bought new lower ball joints from him 3 years ago, I installed them, went to get the suspension aligned and the alignment shop told me one of the lower ball joints was shot...I replaced the ball joint and sent Bill the one in question....he confirmed it was no good and admitted he had never seen that before...I believe it was a Raybestoes part.... He refunded the money for the part...unfortunately I had to pay the alignment shop for removal of bad ball joint and installation of new.
