Have a problem with my speedometer . I replaced the cable when it broke and replaced it with a new one but then the speedo started making noise and the speedo was jumping so I purchased another new cable and installed, the noise has been reduced but it hasn't gone away so now I'm thinking it might be the speedo itself . I had the speedo set to zero when My truck was completed . It now has 9000 miles on it . The miles are still adding up but the noise is driving me crazy. What would happen if I gave it a shot of WD. Or another solution might feel to purchase anothe speedometer if you can match the miles . Suggestions thanks Rob
