Great write up!! that might explain a few things for me. Two years ago I was working at a repair shop and deicded to put a posi unit in my rear ( this is before I researched things lol ) turns out it didnt work, so I put my old diff in and had my friend use a back lash tool cause i didnt know how it worked. about 2 month worth of driving later on it ( cause my car was not runnign for 10 months) i changed my fluid and bearings and seals for the axles, and took off to conneticut. before that I drove around town so it wasent very long trips. By the time I got to conneticut i hada bad humming sound, and drove back home with it. here my passenger side bearing locked up, but why? I went to remove the axles to replace it, and as I turned the diff, i was missing teeth!! here the metal shards from the teeth messed the bearing up. The ring and pinion were set too tight, so I guess he knew just as much asbout it as i did about the tool then lol. so moral of the story is, dont let friends do the work thats for professionals.
