The speedometer needle flickers at certain speeds. My Haynes manual claims this is caused by vibration which is often created by to sharp of a bend in the cable - apparently all bends should be less then 4cm radius or something like that. There are no sharp bends in it. I did strighten some sections out and this stoped the ticking noise it was making but it still flickers. I un-fastened the coupling where it attaches at the speedometer and this area looks healthy and well lubed. Not sure what to do next. Is this a worn cable? There is only a 111,000 miles on the speedometer and cable. Anybody else experience this problem?
