I need some information! I replaced my speedometer cable about a month ago with a new GM one from PY due to some fluctuation between 10 & 30 mph. After about 50 miles of no problems, the speedometer developed a loud screeching noise and fluctuation from 10-60 mph, but will stabilize (also less noise upon deceleration). I pulled the cable out of the trans and turned it and still had noise from the speedometer. I have disconnected the cable from the speedometer to avoid further damage. Is there anything to lubricate on the speedometer itself? If I need a new speedometer who has one or can this one be repaired? This really has me baffled. Has anyone has a similar situation?

Hey, Maybe a long way off here of what your asking but I've got the SAME problem with my wife's *ord van, replaced it once (cable & speedometer) It was fine, then about 30K miles later did it again but its not under warr, now. That's how it goes right. Just waiting to trade it in on a Grand Prix GT. Anyway your not far from me I'm here in Greenville S.C. Have a '69 GTO Conv. Give me an E-mail sometime. ( [email protected] )Happy Holidays

I had the same problem with my 67 GTO ragtop (orig owner)several years ago. Good move to disconnect it. I didn't, & the jumping around broke off the dial. Tried replacing the cable, housing, etc to no avail.
Finally had a mechanic take it out & sent it to a speedometer shop in San Antonio to fix it. Don't remember what they did, but they did get a different needle on it. It still jumps a little around 10-20 mph (esp in cold weather), but alot better now. Good luck! |

The speedos all have an oil impregnated bronze bushing in them, it's pressed into the frame assembly and it's not replaceable by any back yard mechanic, you have to have this bushing replaced about once every 30 years or so as it will dry out and cause the speedo the flail all over the dial, it's going to ruin the speedo in a short time if you keep driving it that way. There is no way to re-lube this bushing the oil is pressurized into it during manufacture. Whenever you take the speedo all apart the magnetic field will be broken and you have to re-calibrate the speedo on a special machine.
