	Or in rare instances, the gear in the tranny. Or the bolt backed out  
and spit the cable. Luckily it's all simple to diagnose. Was your  
speedo bouncing, especially at lower speeds? Any new leaks under the  
car?
	Just pull the instrument cluster and if the speedo cable is  
attached, unscrew it then unplug the necessary wires and finish  
removing. Pull the inner cable out and inspect it. Both ends should  
be square and no fraying evident. If the cable appears to be intact,  
the drive gears can be verified by either driving the car while  
watching the cable spin (or not). It may seem to jump between pauses,  
that would indicate missing teeth. Spinning the speedo will verify  
its operation. I have a short length of speedo cable that I chuck-up  
in a portable drill for this purpose but you can spin it with your  
fingers too.
