WHy is my speedo jumping and chirping??

Lately its gotten really bad. The needle will vary 10mph back and forth and it's chirping horribly. Very VERY distracting.

What do I need to do to fix this? Oil on the gears? Tighten something? I would really like to get this little issue fixed because its super annoying.


Any help is appreciated. Thanks guys.

Sounds like 20+ years of crud has gummed the works. Try cleaning and relubing. Instructions below:
