Clucking Speedo
My dashboard is starting to sound like a hen house. Speedometer and odometer otherwise work fine and are accurate, it's just the noise that is driving me crazy. Disconnected the speedo cable and noise went away, also inner part of cable looks good and still has plenty of goo on it. I'm sure the speedo itself is either worn out or dry. Started to take apart an old one I had laying around, but looks like lots of potential for making things worse trying to "fix" it.
Anybody have any luck with one of these, or do I just bite the bullet and buy a new one? The other question of course is if a rebuilt original is better than a new repo as is the case with so many of our parts these days. Thanks for any help or opinions, Tom

Re: Clucking Speedo
Likely that plenty of goo is the culprit.
Pull it out, clean, relube it and see if that helps. I’ve cleaned them with acetone and lubed with wd40. Likely not the best cleaner or lube but worked for me. |

Re: Clucking Speedo
I know you've looked at the cable and it is lubed, but that would be my number one suspect. When mine made that noise i pulled the cable innards out and hit it with some fresh synthetic grease and the hens and chicks went away. The guts of the speedo are about the size of small clock parts, not really much there to make that kinda noise.

Re: Clucking Speedo
I have a speedo from another cluster I picked up that makes a similar noise. Something inside the speedo broke, but I'm not sure what it was that broke. The speedo that was in my truck worked well, but the odometer roll had locked up. I sent the good speedo off to member TBone64. He put a good odometer roll in and made sure everything was working good and looking great. It's been in my truck for about a year now and still works great. I highly recommend his work

Re: Clucking Speedo
Thanks all for the suggestions. As soon as I get a chance to get back to it, I'll post what (hopefully) cures the problem.

Re: Clucking Speedo
Just an update,
Re lubed the cable and while the noise didn't go away, it did change, so I knew I was on the right track. Interestingly what made the noise go away completely was pulling the cable a little ways back away from the firewall and tie wrapping it to the steering column so it had kind of an S shape to it. Don't know why but that did the trick. Thanks to all who replied with advice. Tom
