Also, the worm gear, the one on the drive shaft,
slides back and forth. Is it supposed to?

i'm afraid i need some further clarification. it's not clear if we are referring to the speedometer gauge on the dash, or the "turtle gear" mounted to the transmission, when the phrase "worm gear" is being used.

have both been taken apart or removed from the car? if so, which ones are they, and which gears of each are we referring to when speaking about worn gears, or turning or not turning when a test is performed?
