squealing speedo question...

Dear shop grunt:

No need for a rebuilt. There is a bushing on the input shaft which eventually runs out of lube after......40 years! You can work light lube in there without disassembly, though the thing is at an odd angle and taking the speedo out of the dash makes it easier.

This site shows the "innards" and how to take apart:

thanks- i'll give that a look- could i just put a few drops of wd-40 in there? or ? grease or graphite? teflon lube?

Maybe 3-in-one light oil? I think most folks prefer a light grease for some permanence.

Lot o' ways to skin the cat :-)

Another culprit could be the speedo cable it'self.

you can try to spray some lube in through the cable connection....or you can remove it and disassemble it and clean all the old crusty grease out and then regrease it....i did the latter...worked great.... here are a few pictures of a 68(one year only) speedo....(posted this for someone that wanted to know how to change the "gels" in the speedo...but you can see what is going on...if you need anymore detailed pics of the inner workings let me know, i have two other 68 speedos disassembled now....the wife would love to see them gone off the counter)

Last winter I had this problem, the speedo was screeching intermittently. I traced it to the speedo cable, but ever since I bought a replacement the noise has disappeared, typical!
