Guys,
I've noticed that when I go over a bump while turning right, I often hear clunk/thud(?) noise. So first thing I checked was a cv boot(outer) and discovered that rubber boot split in two. Therefore, I've visited a few local bmw specialist shops and got quoted as follows (part/labor):
1. Replacing the outer cv boot only = $450
2. Replacing with an aftermarket axle = $450
3. Replacing with a factory axle = $650.
What do you guys think about these quotes?

Is anyone here from austin, tx?
Any input will be appreciated!
