Hi Bert, I had the same thing happen on my 66. An occasional grinding/squeaking sound that had the speedo needle bouncing in rhythm. I would wiggle the speedo cable, loosen then tighten the barrel connector at the speedo thinking it was the cable. Then one day while watching the needle bounce the sound stopped and the needle dropped to zero. Changed the cable and still nothing. Took the old cable, hooked it up to a drill and watched it spin on the other end ok. Hooked it up to the speedo and nothing. So I've deduced my speedo broke. Now I just need to find a good used 66 t1speedometer. -pete Fairfield, CA

Volks, My '70 has developed a noise in the speedometer. It's intermittent, of course, and can't always perform on cue, but when it occurs, it issues a "chud chud chudchudchudchud" noise that keeps time with the wheel revs. It might stop for a few minutes, then mysteriously resume for no apparent reason. The speedometer needle is generally pretty stable, but occasionally it goes into wild gyrations, then settles down again. It seems to show a pretty accurate speed (just gauging by the feel -- it reads in km/h), or at least to average a fairly accurate reading if it's doing its dance. I replaced the buffer resistor, but there was no effect. (Full disclosure: The replacement was also very old.) I dread tearing stuff out to gain access to the back of my speedo again, but when I do, I'd like to know whether I'm going to encounter something minor (a tube of cable lubricant) or major (a removal/rebuild of the unit). The cable and speedometer are both 40 years old. Does anybody recognize the symptoms I've described? What might I be in for?
