Re: 66 c10 electrical/cluster q's

Bought a new cable and installed it, then I did the reversed drill attachment test and it made a racket in the speedometer but the needle was moving. I lowered the rpms and it still has a clackety sound in there.

Took it for a drive and the sound was drowned out a bit by the motor/road noise but its there. Even noticed that the needle didnt glide but was shaking a little as it went.

I removed and took apart the cluster and cleaned things up and checked the speedo to see if anything was lodged in that might be making the sound and saw nothing. The needle itself seems to be the racket making vibrations. Is there some kind of bushing that it should have at the needle base? Cause its pretty open down there.

Anyone ever run into this? Does this mean I should replace the speedometer or is there a potential fix?
