8 1/4 axle inspection.

I went to an art supply store. I think I bought a tube of cadmium yellow, squeezed out a dollop and mixed it with some axle lube and used an acid brush to apply it to the ring gear teeth. If you don't have the special tool to hold the yoke, maybe you could hold it with a big a$$ pipe wrench, while you loosen/tighten the pinion nut.
