car is a 1977 300D. Been about 50k miles a little over a year since I changed out speedo cable. Got in car this morn and going down road noticed nothing happened. No speed, no trip odometer (tried zeroing in) movement, no main mileage odometer movement. This was right after starting the vehicle. We had a wicked yankee clipper come through yesterday so I figured maybe things froze up. Got the cabin nice and toasty and ran the piss out of the car on the express way for about 15 miles. No go. Symptoms seem to indicate speedo cable. Do they only last 50k miles. Last time I did the cable I had the odometer sent off to have serviced. Any thoughts please. Tom. I think you can expect the speedo cable to last about 100,000 miles if it is properly installed with no kinks, etc. Several of us have experienced failure of the first drive gear, just inside the speedometer head. This is usually preceded by a squalling noise, not unlike a failing drive cable. This gear is part of the calibration of the speedo with the axle ratio on my 79, so must be replaced with the same exact gear to retain an accurate speedometer. I got mine out of a wreck at Upull .
