Hello, I am running into an issue with reading the paint on my ring gear. The pinion doesn't really seem to want to remove the paint. The first time, I thought maybe there was still oil on the gears, so I took it apart and made sure to clean the ring and pinion real good. It got better but still not showing much. Based off the pictures attached. I think I need to install a thinner pinion shim. I installed all new bearings and used the old ring and pinion (original pinion shim). I am within .005-.010" backlash, but I'd just like a second opinion. Also, if I need to install a thinner pinion shim, how much thinner? I haven't really seen anyone talk about pinion shim thickness.
