Need advice on axle shaft

Hey guys, Well I've got 110,000 miles on my 2016 tundra. Haven't done much besides regular oil changes and rotations(I know I'm bad). ABS and traction light came on a few months ago but went off after a couple days and thought maybe it was a glitch in the sensor. Took it in today after a week or so of the light staying on. They are telling me the R wheel bearing is shot and grinded on the axle shaft, shock is leaking bad, and obviously the sensor is trashed. Along with this I needed to get new front brake pads and rotors resurfaced (significant pulsation when I touched the brakes). For this work they are quoting me $2400. Obviously not what I wanted to hear on a Monday. My question is: Does this seem reasonable? My biggest concern is the axle rod, I know the bearing and sensor need replaced but didn't now if "scarring" was possible on the shaft.

 

My guess is yes scarring is possible but someone more knowledgeable than me will know .

 

If you ignore the early warnings, the cost of the repair goes up with more progressive damage. It sounds reasonable to me but without seeing a parts and labor breakdown we've really got no way to compare. Get a detailed quote or a second opinion if you can. But in all reality you don't strike me as someone who's going to proactively do such a thing and you just want to whine about a $2400 bill. Seems cheap for the years of no additional maintenance added! We hope you get another 100k miles out of her too!
