If your speedo is jumping it means that one of the speedo cables has a "whip" to it meaning if you pull the cable out it will tend to curl or not lay flat and straight when you put it on the floor. This condition will worsen and eventually the cable will fail. The only cure is to replace the cable. Make sure all of the bends of the outer cable are as gentle as you can make them, Sometimes lubricating the cables will help if not too bad. If you have bought all of these parts from Grady call him as he offers support for all parts that he sells and he has an 800 #.
