2002 BMX X5 4.4 outer cv boot.
Here is my experience doing this work.
0) Only removed the control arm bolt.
1) I tried vice grips/bar and banging options to pull the outer joint with no success (even rotated rotor a few times).
2) Opted for inner boot alternative but had to order it (GKN). Also ordered snap ring pliers. I had to wait for part but this option worked very well as others have done it (only messier).
3) I had a hard time using the clamp plier tool under car (no good leverage). So ended up ordering 'OTC 4722 Stinger Heavy-Duty CV Boot Clamp Installer’ from Amazon and the tool worked great. I strongly recommend it.
4) I was unable to torque the control arm nut/lug with wheels on floor. So I got a hold of a couple of 4x4 blocks that gave me enough space and leverage for the torque wrench.
5) I reused the control arm bolt and nut. I’ve driven the car for some time now and checked it a few times and looks OK. I should have installed a new one for peace of mind but just wanted to get the work done.

I spent a week on this including time spent waiting for the parts/tools and googling for options/ideas. Now that I know what to do and have the proper tools, I think I can do this in a couple of hours.

The net is... Order both inner and outer boots, buy control arm nut and bolt, and get the right tools. Job should be done in a couple of hours.
