Here's a Lexus dealership price for some of that
In case anyone was wondering why they're called stealerships, both diff fluids were changed just a few thousand miles before this shakedown (and I had undercoating on which was untouched, they didn't even loosen either diff bolt), the coolant wasn't even at the "low" mark in overflow, rear pads were 5-6mm, etc. I stopped at an independent shop on the way home and got it inspected without doing a thing.
