I have my 96 3/4 ton Ram in the shop for brakes, wheel bearing kit and a axle joint. The owner of the garage showed me the Backing Plates from each wheel. they were almost completely disintegrated/. The Dodge Dealer said they are unavailable so he had to leave them out. He said he made allowances for the missing part. What I would like to know is, can I drive like this and not expect a problem. Also it is hard to imagine that this part is not available. How about some comments?
