I just replaced the lower speedometer cable for the second time in nearly two years. The first time the cable bit the dust the dealer replaced it along w/ the VSS (it also would not shift out of 1st). Last week the speedometer stopped working but the car shifted normally. I got a new cable from Ford and put it in myself. Has anyone else had repeat problems w/ the cable? Why did the VSS go bad the first time when the cable severed and not this time? I made sure the cable routing did not have any severe bends and even lubricated the top connection. I hope I do not not have to replace the cable every 2 years. The car has only 36k miles. The first occurence it had only 18k on it. Anybody out there w/ similar experiences or insight/suggestions I would love to hear from you.
