Looks like you're on the right track to me. One critical thing to note when you have ABS and you also replace the bearings is the diagram that you've posted about how far to correctly press on the ABS ring and the retainer ring. There is a gap between the ABS ring and the end of the bearing. Many techs don't realize that and just smack all the pieces together. If you smack them together, the retainer ring doesn't make a proper seal against the inner axle seal. If it immediately leaks again after the bearing was replaced, you know the tech likely messed up the spacing there - plus if you look at the ABS tone ring through the axle housing where the sensor goes, you'll see that it's not centered like it should be. One tech I talked to said they sometimes smack all the pieces tight together and then add 2 retainer rings in the hopes that that will be OK with the seal there. I don't have experience to know if that method actually works though. Good job on noticing the need for correct spacing there. I'm just reiterating its importance after a painful experience for me related to that topic.

Another thing to note is to be sure the C-clip or snap ring or whatever it's called is properly in place to hold the bearing there. Otherwise, you can lose the entire wheel and axle as you watch it pass you on the road. I've heard a couple people describe that one.
