Jacked up and turned wheel and marked high spot on wheel runout. Removed wheel and re-positioned and turned wheel again. High spot on wheel stayed with axel position. Removed wheel and drum and re-installed wheel and tested again with same results. On the same car the left front wheel was shaking as well so I did the same test. It turned out to be the brake drum made wrong, thicker at one bolt hole than the opposite one. Neill
