Spedometer cable help!

[mckabe]

So I was driving today and all of a sudden my spedometer started jumping around then went above 85 and started making a really loud annoying noise that almost sounded like a fire alarm. I removed the speedo cable and it seemed a little sticky. Festeve told me to try some wd40 do I did cleaned it up real nice re installed. Same problem even tried some wd40 in the tube too. No luck. Any suggestions, anyone else with this problem?

I had that problem with my 95, all it was with mine is the spline wasn't clipping in right into the back of the cluster. It was worn, but if i push it in by gaffa tape its fine lol. It died when i was interstate it was the only fix I could do lol.

Ny way to tell if it is clipping in right?

[BrianFestiva]

If you disconnect the cable from the gearbox you should be able to push/pull it through the fire wall, not all too much but enough. So when you take the cluster out you can see if it is clipping in or not.

Tried everything, but I managed to fix it. The fix is called street race app for android

There is a brand new speedo cable on Ebay right now

Here in Aus there are plenty sitting out in the wreckers that are still good!

Once in my BP car my speedometer went up above 85 and I heard a really loud noise... then I realized I was still in 3rd gear and promptly shifted to 4th. After that the noise quieted down... till the next red light turned green LOL

Seriously though, if you need a new cable I think I have a couple good ones laying around, but usually when the cable has a problem the speedo reads LOWER than it should, not higher.

[mckabe]

I don't think its the cable, possibly the tube.

[htchbck]

Possibly, but if it is reading higher than it should I'd put my money on something being wrong with the speedo head (return spring broken or loose) rather than the cable/tube assembly. If it was the cable and not the head then that would mean the cable was somehow spinning FASTER than its supposed to, not sure how/if that would be possible.

Mechanical speedometers work by spinning a couple of magnets inside an aluminum cup attached to the needle and restrained by a hair spring. If you get a bit of dust inside the cup and it is very cold (10 - 20 degrees) the magnets rub on the inside of the cup, whack the needle against the stop and make a screeching noise.

Happened to me in a 1967 Chevy pickup at about 5 degrees. BIG screech, pop, wrecked the spring, and broke off the needle.

I have had some get catchy in cold weather, but when the inside of the car warms up, be fine.
