Shop Wants To Replace Differential Assembly

If you don’t mind… what kind of shop should i look for? Like a transmission place?
Unless you live in a swamp, Swfl leaves a lot of guessing as to where you are. Someone might know of a great shop in your area if they knew a slightly more accurate location.

1) Buy the tools needed and the parts, fix it yourself.

2) Just pay someone what they want and let them do what they recommend, it’s not like you don’t have the dough.
