Your concern about finding someone who understands backlash setting properly is the right thing to focus on when comparing workshops. Differential work done without correctly setting pinion depth and ring gear backlash produces noise and accelerated wear that brings you straight back with the same problem within months. Asking any workshop directly how they verify backlash settings after a differential repair tells you immediately whether they’re doing it properly or just assembling parts and hoping for the best.
