Speedometer bounce
#1
Any idea why my speedometer constantly bounces +/- 10mph at speeds up to 35mph, then smooths out for all speeds above there? Is there a way to fix it?

Thanks,

Doc

Speedometer cable. I don't know how many speeding tickets I got out of with that excuse when I used to drive our old 69 f100. Once replaced, I never could use the excuse again. Would bounce real bad and slowly settle till I was about ~50mph. Worst case is the speedometer itself but that wasn't my experience.

+1 on the cable. Mine does it too. Just too lazy to remove the cable and lube it. Eventually it will break and I'll have to change it.

Hey Coilwire -

That's not me - you'll have to get more details from 71Mach351. If it were me, it would be the police car PUSHING me to get up to the 45mph minimum speed limit on the freeway. Smile.
