I have been fighting a propeller shaft problem for years now on my 1950 3100. Have owned the truck for 28 years and this is my second okie bushing/prop-shaft combination. The problem is the clearance between the front bushing and the prop-shaft is too tight on the high side of the shaft. When the shaft spins it scores around the shaft. I have had the prop shaft on the bench on centers and have gotten it to within .003 but that doesn't fix the problem. I am thinking that the outer shaft might have a bend in it, but I have no idea how to determine that. My last resort is to find a replacement torque tube assembly and give that a shot. Has anyone out there dealt with this problem? Thanks for any suggestions.
