I've been chasing a shake in the rear of my 1996 Ram 3500 2WD. I had the rear brakes redone including drums,new shocks and still had a shake that would come and go at different speeds and on different road conditions. I gave up and took it to an alignment shop to have them balance everything on the rear. First he said that I had the wrong drums on it. Then he called and said it had the wrong wheels on it. The rims wouldn't fit over the drums properly. He claimed they are Ford rims. I managed to find 6 used rims but they look the same to me. Am I missing something here? My back is against the wall here. We're supposed to be hooking on to the fifth wheel camper to go camping for a week.....
