The speedometer cable gear is broken inside the transmission. If the car is older, it is an easy fix. Follow the cable to the input on the tranny, unscrew the cable and the gear is right there. Pop it out and replace it with a new one from the auto parts store. They should be able to order it for you.

What else can be wrong with spastic speedometer needle on a 1996 Ford Escort station wagon the speedometer cable and cluster have been replaced and the speedometer still doesnt work?

So the speed gauge in the dash and the speedometer cable have been replaced. Well, the only thing left to my knowledge would be the geared speed sensor in the transaxle. I have the same problem. Replaced the speedometer cable but to no avail. I then took the speedometer out and used an electric motor to drive it on my bench and noticed that the part that is driving the needle (driven by a magnet) starts vibrating at certain speeds. On further investigation I found that the bush on the panel that the spindle goes through ( just behind the needle) is worn and hence the spindle/shaft does not run tight and starts vibrating/rattling and then it sometimes swing up and down. When I lightly touch the needle it stabilizes for a while and then starts vibrating again. The needle is not driven directly, but through a magnetic coupling so the slightest interference can cause problems. It seems the only solution is to replace the speedometer. Unfortunately you have to replace the whole cluster. I thought I could do something about the bush, but it is too delicate and you will have to remove the little coil spring which means the speedometer will have to be re-calibrated.


What causes speedometer not to work on gm alero?

If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.


Why would the odometer stop working in a 96 Ford Explorer?

The odometer on a 96 Ford Explorer is tied into the speedometer. If the speedometer is working then there is a gear problem inside of the speedometer causing the odometer to not work.
