Has anyone done front wheel bearings DIY?

[speedyspaghetti]

I'm pretty certain my vibration issues is due to bad front bearings because I have literally replaced every other steering and suspension component and it's still there.

Has anyone done this DIY? I have a few questions:

1. How challenging is it? I've done struts, control arms, tie rods, etc.

2. I'm guessing I need the SIR kit to extract the bearing - is there any way to get it cheaper than the $390 that Pelican wants for it?

3. Is it necessary to take the carrier off the car to do this? I had a ball joint remover, but it's a cheap one from O'Reilly that I used for my coffin arms and tie rods replacement when it didn't matter if I ripped the rubber boots. Should I buy the Porsche specific one? Or is there another tool? I just replaced the control arms and tie rods, so I really don't want to rip the rubber on those.

4. Are the FAG brand bearings considered good quality?

Thanks!
