numero uno, if the 1/8" music wire is bent in such a way that the "axle" is distorted, then no amount of oil or grease will work. After forming the torque rod, it should be rolled on a flat to make sure it is straight with no wobble. The torque rod should be formed with the axle in smooth vise jaws and hammer the legs over. I've been doing it this way for a couple of years now. I used to use axle grease, but a drop of oil works just as well.
