speedometer erratic operation under 30mph

[the1968jeepthing]

the stock spedometer on my truck tends to jump up and down untill i reach about 30mph. i heard that this could be caused by a dry speedometer cable. if this is the case, how would one lubricate it other than spraying fliud down the ends? (i tried that and i dont think its getting the entire cable)

Wow...theres a new one on me....
All I can give you for info is that I had to change mine cause it broke, and the new one came with a grease in there....like a lithium grease it seems...dont have a clue how you would grease the thing...
Sorry I cant help more....

hmm, although its not a huge problem and it doesnt bug me that much the cable itself is not looking too good. i should probably replace it soon anyway. where did you get your cable and how much was it?

My cable was broken when I got the truck. I put in a new cable, but not a new case. It broke after driving about 10 feet. I then pulled the speedo out and took it apart. I cleaned and lubed everything inside with grease. Put it back together and put in a new cable. Worked great until I put in the Autometer stuff a year or so ago.

I just baught a generic replacement at NAPA. I think it cost around $12.00

An instrument guy who calibrated my CJ speedo for a competition told me that vaseline was the best lube for a speedo cable. I have never tried it but it sounded good. Pull the cable and housing out. Spray a whole bunch of carb or brake cleaner through it. Blow some compressed air through to get rid of the cleaner. Lube the cable well with vaseline and feed it through. I think I would tend to try to find a large syringe like at a vet or something and pack it full of vaseline and inject it into the housing before the cable.... anyway...

I bought the cable from Surplus City I think...either there or Memphis....its been a while....anyway, if you have never taken the tcase end off, you are in for a treat...putting it back on is a pain.
I remember someone posting about a CJ(?) cable that fit...check the parts list....
Yepper...this was posted back a while:

a speedo cable from a '77 - '79 CJ-5 will work. I was in a pinch and used the one off my CJ-5. Order the longer cable.

Not having much luck replacing just the cable in the past, I always replace both, by the time you replace the cable twice, you are about there anyway. We always used graphite powder for lube, right or wrong?? Glen
