Speedometer moves around when stopped...
Recently my truck started doing something weird with the speedometer. When I come to a stop, it the speedometer needle sometimes moves around between 10 and 15 MPH. It doesn't do it all the time, only when at a complete stop with the engine running. There is no change in engine RPM, and the truck doesn't move at all, so it's something with the gauge, a ground, or speed sensor I'm guessing. When moving, the speedometer works fine. No ABS light or anything.
I know the rear speed senor is a common problem with these trucks. Could that be causing it? What else should I check?

Well it looks like I will have plenty of things to check then. Corrosion and a loose ground are both very possible with this truck. I've gotten some water on the inside on many occasions and it's been down its fair share of rough roads and trails. It just seems very odd to me that it only happens when stopped at idle, and that the speedometer seems to function normally and accurately the rest of the time.
