How mechanically inclined are you?
I can't tell from the pictures what the overall problem is. It could be that just the seal got dislodged during removal/reinstallation and the rest is fine.
I would start by taking the hub/spindle off and reinstalling the seal. Then you can look at the bearing surfaces and bearings and make sure that everything is in good condition and lines up properly as you install it.
Do you know how to do wheel bearings in the general sense?
