This suggests that you have a mechanical speedometer system which uses a combination cable consisting of a rotating inner cable inside a fixed outer cable. That cable runs from some source of rotation [normally the transmission, but sometimes from a wheel, or if so equipped, a speed control [Cruise Control] device. Often a vibrating, "jumping," or "ticking/clicking" speedometer cable is an indication that the lubrication [grease or other form of lubricant] between the inner and the outer cable has failed. Mechanical speedometer cables usually are attached to the source of rotation, and the back of the speedometer, with threaded screw-on connector rings. The ends of the inner cable are usually "squared" to fit into square openings inside the speedometer and the source of rotation. If failed lubrication is the cause of the symptom you describe, then the "fix" is to locate the cable, disconnect one end [the easiest is usually the opposite end from the speedometer in the instrument panel] pull the inner cable out, clean and lubricate it, reinsert, and reconnect the outer cable. NOTE: The squared ends of the inner cable must fully insert into the matching square holes in the speedometer and rotational source, so it is necessary to slightly rotate it while reinstalling the inner cable. If it does not properly "mate" with the square opening, then it will stick out to far to allow reconnection of the outer cable from where it was removed.

What would cause the speedometer needle not to work when the headlights are on?
If it's an electronic (analog) speedometer needle, you probably have a problem with the dasboard grounding.
What could cause the ABS light to come on and the speedometer needle to bounce intermittantly on a 1996 E350 7.5L gas?
I would suspect a faulty VSS. Try replacing the vehicle speed sensor in the transmission.
What would your lower stomach to vibrate?
Muscle spasms can cause this.
What would cause the speedometer and odometer to fail in a '97 Saturn S12?
sounds like a broken speedometer cable.
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 kind of speed does a speedometer show in a vehicle?
Acceleration is not represented on a speedometer, however, when you look at the speedo, if the needle is moving, you can get a rough idea of acceleration like this: If the needle is going clockwise (of generally indicating faster speeds) - you are accelerating. If the needle is going anticlockwise - you are decelerating. Speedometers measure speed. You would need an accelerometer to measure acceleration.
Would bad motor mounts cause steering wheel to vibrate?
yes
What would cause the speedometer to not work and the odometer to work on a 1999 Mercury Cougar?
The gears in the speedometer are stripped. If the odometer is working then you have input.
What would cause a 1994 Chrysler lhs not to shift out of first gear and the speedometer is not working?
TCM Malfunction, And/Or Speedometer Sensor Malfunction.
What would cause the speedometer on a 1996 dodge neon not to work?
i would have to bet on the speed sensor
Why does the needle for the speedometer bounces around while driving a Ford Windstar?
I would suspect the vehicle speed sensorSee "Related Questions" below for more
What would cause speedometer to work intermittently on 1996 Honda Accord EX?
The speedometer on a 1996 Honda Accord EX is the pulse variety. It is likely that the teeth on the speedometer gear are not meshing properly.
