I had my Dana 44 rebuilt but only because it was the easiest to do and I never plan to wheel. Beefier difs are nice though so don’t rule it out. I wouldn’t say your axle is shot it could be a bad ball joint or something especially if the shop sucks. I would do some measuring on the knuckle first to see if it’s lined up right and check the ball joints. If they are old replace them. It’s not hard to do just get the right tools. No need to have a shop do it. Camber can be adjusted, but it requires a special ball joint which I have never heard good things about and if you put in a good ball joint it won’t need adjustment.
