How can a mechanical speedometer be 10 MPH slow and the next day be almost dead on. GPS check.
I’m guessing either the gears inside the speedo are dry (grease dried out?) more friction, spins slower, or maybe temperature related? Cold speedo lube, more friction?
Good places to check. Thanks.
Or a crummy aftermarket cable. My speedos perform fairly well using a somewhat worn out, abused, 33 year old cable on the bench, but they do the same thing as yours in my car. I have yet to find a cable that even comes close to the OEM design. I’m on the verge of saying screw it and just putting the dinosaur cable back in.

Oh great, is this going to make it to the square body quote thread?
using OEM cable, at least it looks like oem cable.
My speedo does the same and the faster I go the more accurate is my speedo. I have tried 3 different brand speedo cables and all of them sucked. If I ever find a good speedo cable that works as expected I'll post it.
What about LMC speedo cable? works well?
