I just figured the kroil might loosen it up first. Then use the light oil. Seems to me that it needs to penetrate to loosen up the old dried crud that is making it turn hard. Just checked it. Still turns too hard. Does anyone know how to get that shaft apart to sand/oil it? I'm talking about the speedo shaft where the cable goes into the back. Looks like I might have to replace it. One thing is for sure when it comes to mecanical stuff. USE IT OR LOSE IT cause it's just gonna deteriorate if it just sits there!!!! GET THOSE GARAGE QUEENS OUT AND DRIVE EM!!!!
