Most of the time, 99.9% of the time my speedo will not work, changed the rear end sensor, to find out that probably did'nt have anything to do with it, also messed around with the gear, on the transfer/tranny. But most of the time, if its rainy out, or currently snowing ( I have a plow on it), my speedo will work, sometimes its right on as far as accurate, but most of the time, it will read double, speedo says 60, acutally doing about 30, but the odometer will rack up the correct milage. Forgot to mention, either they both work together, or they both don't. Just sometimes, when they are working, sometimes the speedo is way off. Any idea's??
Thanks
