What causes a speedometer to make a buzzing noise as you drive? THe buzzing increases with speed, so I assume it is tied to the rotation of the speedometer cable and the gears inside the speedometer. Can I take it apart and lube something or tighten something up to make it go away?

This is on a 83 Dodge van.

Try lubricating the cable. Also inspect the cable housing for kinks and dents where the inner cable might be binding.

Growing older is unavoidable but growing up is strictly optional.

Thanks! I will get a tube of graphite and lube the cable.

Vaseline will work too.

What you have is the infamous "Chrysler buzz".

Thanks big D. I'll give the Vaseline a try too.
