: the contact stated the speedometer failed and while making right turns there was a clicking noise that seemed to be coming from the front passenger wheel. This occurred while driving at various speeds. The speedometer was always stuck on zero and the mileage of the vehicle became unreadable. The speedometer has been replaced three times by a local dealership, however the problem still occurs. The dealership was unable to duplicate the problem with the speedometer and determined the front passenger wheel bearing needed to be replaced. The manufacturer has not been alerted.
