Lower control arm bushing

I have no idea! You would think after enough returns they would look for the problem. With Moog all you pay for is the box with the name on it of the three sets I bought two of them had different rubber in them and if you compare the Moog and the AC Delco they are made by the same plant in Turkey. Federal mogul sold the Moog line to someone who is just getting them where the best deal is and putting them in the Moog boxes.
