Try driving the car with the cable disconnected from the speedo and poking
out where you can feel it as you drive - any vibration?
Try driving the speedo directly with a drill, and via the cable with a
drill.

>This weekend, I replaced the recently installed speedo cable with a longer
OD cable in hopes that it would quiet the god-awful noise from the dash to
no avail. Noise continued until the speedo dropped to 0 and stayed there.
When I was driving during the noisy phase, I could feel the vibrations on
the face of the speedo. The cable enters the firewall at the master
cyclinders and travels in the dash to the rear of the speedo and enters the
speedo as close to a straight entry as I can. No right angle drive on the
speedo.

>Any thoughts? Could the speedo be bad? I traded my other unit with a
fellow lister a few months ago and has never seemed to work properly. Could
the right angle drive on the transmission be bad? How would I know?
