Speedo Quit but Odometer Works???

[RaptorMike]

Just like the title reads. My speedo has always bounced around like a bobble head and then yesterday it just quit. Today it was making a bit of a grinding sound and bouncing backwards. The odometer has worked the entire time. Before I tear out the cable has anyone else had this issue? I've never torn into a speedo on a Bronco and I'm a little apprehensive about it.

The spinning magnet or cup (I forget which one spins), isn't.

Mine is doing the same thing. Haven't had a chance to look into it yet. Hopefully somebody will post back and let us know what we need to fix.

Mine quits working when it gets cold and starts up again when it gets warm. I guess it's just taking after it's owner
