Since you said any help, i had a guess. I would think that noisy gears would be more of a function of backlash, then side to side play, as i guess the shims would take up the play. If it were me i would call around to a few transmission shops at there non peek times and ask them. I think there is other components too in there besides gears, like for limited slip, posi traction...etc.. Sorry never had to work on a differental. Went from Motorcycles to front wheel drive.
