I replaced the brake shoes/hardware on the left side side this morning on the '52 8N. I did crank down on the axle nut with a long cheater bar. It does not have the wire retaining do-dad that I have seen in pics of this. Is this something that is really needed or a type of safety device? The right side does not have it either so if I replace, I need to do both sides. I'm glad I decided to check the axle nut and wheel nuts on the right side before putting everything up, it was loose by about 1 1/2 rounds on the nut. The wheel nuts were also somewhat lose (about 1/2 of them). I was quite surprised at that! Does the retaining wire for the axle nut keep it from working loose like that? Thanks, Gary.
