1990 Ford F150 6 cyl Four Wheel Drive Manual

The speedometer on my truck stopped working a while back and for a while it would jump when I would slow down or push the clutch. Now it doesnt work at all. I have replaced the cable and the gear and after each it would work for about a day then stop working completely. Can you please help me figure out whats going on with it?

Have you rechecked your work and parts you replaced? I ask because if the cable and the gears are both good, then chances are the speedo itself is bad.

Let me know.

I thought you replaced the gear in the trans? If you haven't, yes it could be bad. I believe it is a nylon gear.
