Wheel bearing DIY? Or any advice

[flatlander]

I've searched the forum and haven't seen too much on wheel bearing DIY. I had the dealer do one of my front bearings for $600. They insisted on replacing the hub as well because they said bearing removal destroys the hub and old bearing. The X5 repair manual says the old bearing is destroyed but does not say that the hub needs to be replaced.

What is everyone's experience with wheel bearings on the x5?
Is it worth it to try DIY? Any special tools needed?

My other front bearing is going out so it looks like I'll be replacing it soon.

Thanks for any advice!
