That's nutty money. You should get a 2nd opinion for sure, and some of those parts may not need replacing at all - just the shop spending your money. I did our 285k all original front axle in a single day with parts from Cruiser Outfitters a few weeks ago. Nothing worn out, just worn in and not clicking. Sure you could make that entire axle new save the hollow housing and that's what the shop is salivating to want you to do. That's crazy just for clicking birfs. I see you're new, but swap the birfs side to side so they're wearing on the opposite surfaces and clicking goes away, then new seals and grease and drive off. Your mechanic clearly has a boat payment to make or something.
