odd noise from speedometer

Hello all I recently purchaced a 95 taco 2.4l and i love it. Problem is this however. Sometimes the truck has and odd rythmic squeak from behind the dash. it speeds up when I accelerate and slows down when braking. I think it has something to do with the speedometer because as the sound is occuring the needle wobbles slightly. Hopefully somebody else has had some experience with this. Thanx in advance for any thoughts

 

I've got a similar thing going on. Searching pulled up this thread. See post #7, I'm going to see if I can find a loose screw in my console.

Had a problem on my 89, squeek turned out to be speedometer cable. might want to check that

 

Yep - sounds like a classic case of speedo cable issues ...

 

thanks for the replies guys. Is the speedometer something thats going to be a royal pita or is it relatively simple? Im used to working on a lincoln, so i dont assume that anything will be easy.
