Yesterday I drove the old 300SD to San Francisco. When I started on the
freeway the speedometer suddenly started howling - definitely speed
related - howl suddenly starts at 25 mph and increases from there. It's
definitely the cable end or the bearing into the speedometer.
Normal at low speeds then a full blast howl!
Anyone have this experience??
If so how was it repaired? Cable? Speedo?
