I know this has been asked several times, and I have searched, but I only want to do this once. I have changed the bearings, plastic bushings, and seals in the swing arm. They are in exactly as the old ones were. I have the dust caps with shims, washers, and seals there also. My main concern is shimming the inside of the swing arm. Is there supposed to be any washers/shims (that may have fell out) on the inside of the swing arm to take up side play?
