I just bought a 2001 Road King Classic w a Liberty sidecar set up. it only had 1000 miles on it. I had the 1000 mile service done at Harley a couple of weeks ago. It has this disturbing loud squeak coming from the front every time I shift or cut back on the throttle. Only happens when moving so it is a little hard to determine exactly where it is. At first I thought it might be from the Heim connections where the sidecar is attached so I took them apart oiled, greased, and reassembled them, and made sure all the sidecar connections were tight. No improvement at all. The clutch and throttle cable do not squeak, or at least not when the bike is standing still. Any ideas?
