Hey guys, i'm new to the forum and jeeps in general, but i'm lovin my yj so far. however, i'm having problems with the speedometer. when i'm driving at low speeds, it just flips wildly up and down about 20 mph at a time. it just randomly jumps around, really. it works somewhat well at speeds above 50 though. i checked the speedo gear and it looked totally fine. i spun the gear/cable output manually and the speedometer moved but in the same wild way. any thoughts?? do i just need a whole new speedometer gauge? thanks!
