After studying the odometer under bright lights and magnifiying glass, I couldn't see any stripped gears, and the gears were solidly on the shafts. Initially trying to spin the gears and moving the odometer with my fingers, things were stiff and didn't want to move. After reassuring myself that everything was intact, I used more force and, sure enough, things started moving, including the numbers on the trip odometer.

I'm guessing the gear assembly and oil/grease were a little stiff and needed my finger power to get things moving again. Put everything back together and into the car, crossed my fingers, and off for a test drive. Odometer SPINS! and no more clicking noise.

There was some oil on the gears, but my question is what kind of lubricant should I use on the gears to free things up without gunking things up and causing more problems down the road?
