I hope someone can help me on this, I always seem to wait until the last minute and try to find answers.... When I first started driving my 68 the speedo worked fine. Now, after a few hundred miles, it bounces all over the place. At lower speeds, it goes from 0 to 20, 30, 50, etc. It seems to get better once I'm on the highway at 60+ mph.

Has anyone had this issue before? Does it sound like a cable or electrical problem.

Please respond if you have any ideas. I planned on looking at this on Sat, but just got invited to go to a show with some friends and need to look at it tonight now (late tonight probably )

Thanks
Robb

Mine did something similar except it bounced from 25-35 then stopped. I lubed the cable with cable lube and helped for a few weeks then I replaced the cable and solved the problem for good. Some people have used white lithium rease in the cable for an emergency repair. Good luck and Nice car.

Usually the cable gets bent or dry as Dave suggested. You should probably also disconnect the speedo cable from the tranny and look at the opening where the cable inserts. The speedo gear is plastic and sometimes the gear gets "wollered" (that is a work isn't it) out. But usually that is caused by a hang up of somesort in the cable.

I am having the same trouble. I have my speedo and fuel gauges out of the car out now so I figure now is the time to take care of it. How exactly do you lube the cable? What should be used for lubrication?? I've head someone say you actually pull the insert all the way out and lube it the entire length. I'm a little leery to do that because I don't want to run into difficulty with getting it seated back in properly??
Thanks

Thanks for the info guys.

I unhooked the cable Friday night while getting ready to go to the show and lubed it with some graphite spray. It seemed to get a little better on the way there, but by the time I got home, it was acting up again all most as bad as before.

I just ordered a new cable from a local parts place for $13. Not worth hassling over the old one IMHO.

Honestly if you have the cable out and can wait for a new one I'd buy a new one. My suggestion of lubing the cable is main for someone in a bind and needs the car on the road. If you want to lube the cable there is a special lube for it sold by napa as a speedo cable lube. the manual says to pull the cable out at the bottom put in as much lube as possible and slide the cable back in. I bought an exactly rplacement for Ricks for about 20$. Good luck in whatever you choose.
