I'm in a pickle. These pictures are the rear axle of the old chore truck - the '35 Chevy. I had always thought the clunk when backing up was the yoke in the torque tube needing shimmed. It turns out it was this brake drum rotating on the axle. She's obviously been doing this for many years. It has wollered out the keyway on the axle and the brake drum as well as worn it rather angled.
Keep in mind we're talking parts non existent or used.
Should I true up the oversized keyways and find bigger keystock? Should I weld them up and recut the keyway? The drum is cracked along the outside rim as you can see but it only extends about a quarter inch. I think it is from my uncle putting torque to it to try and keep it from rocking. He had four washers under the nut and a 16 penny nail as a pin. I'm pretty sure that will tack up just fine.
I'm leaning toward going oversized with it. Something about welding on that axle doesn't sound right to me. I know an old mechanical brake drum for that year is rare as hen's teeth. I can't imagine what finding an axle would be like.
