To seal that pinch cavity, you should try some fluid film or some homebrew cavity wax or actual cavity wax. A generous coating 2 or 3 times makes it really packed.

I do nearly the same job you mention, but with a difference, I remove the brake and hub - then remove the whole strut assembly and spindle. That way I refresh the bearings too, usually the grease is toasted too.
