Binding Roadmaster All Terrain
My tow bar was binding so badly that it was essentially unusable. Here is how I finally fixed it. The bracket on the end of the arm can be removed (can be difficult!) by unscrewing it. After that the shaft can be pushed out the back of the arm after removing the rubber plug. Mine was bound so badly that it required hammering to remove.
The problem turned out to be the 4" sleeve in the arm was too snug. I was able to hone it out with a brake cylinder home and it is like new again. I used to hook up and then drive off and feeling the jerk as the arms reached their limits. Apparently this process caused the sleeve to swell until the whole mechanism bound up.
Perhaps this story will help others who are experiencing this problem
