Haven't had an issue with diffs . Replaced one due to it having a lazy LSD . Same with drive shafts had one noisy inner rear cv replaced that , never had issues. I do have some mechanical sympathy .

The box in the car had high km when I put it in and had always been notchy . It lasted 18 months and a couple of track days and the drags so I can't complain only cost 800 bucks .
