82 chevy swb - 2wd. All stock gauges.
When get up to 20mph, my speedo starts making a terrible "ticking" noise. This noise gets louder and faster as the rpms and speed increases. I've unhooked the speedo cable...and the noise goes away. I've even replaced the cable. My question is, do the stock speedometers go bad once they've gone around a couple times? or do i just need to remove and lubricate?
