A 1949 Chevy panel truck, that is the speedometer cable has a loud spinning noise and it makes the speedometer needle to go all over the place when above 30 mph. It's a new cable and the correct one for the truck so why does it do this? More important is how can I get it to stop doing this, could it be that the speedometer heard need to be removed and cleaned and oiled, please give me your insight. Thank you.
God bless,
Dave
