You should not need a wrench to loosen a spindle nut. They are to be adjusted with a very small amount of clearance and therefore there will be no resistance to remove. Once again, you found out that you have to do any and all work to the trailer.
Your photo isn't quite clear enough to judge the wear pattern on the spindle. I enlarged it, and see what looks lire a step outboard from the wear mark. If that is the case, the spindle is hosed. The bearing should be a slip fit with no play. Put the old bearing back on and check for looseness, or better yet check it with a micrometer. It is normal to get some darkening in that location, so when resembling apply a film of grease over the entire spindle to help prevent this in the future.
When assembling, apply grease inside the seal and and between seal lips so it doesn't run dry against the spindle. Of course, be careful that you don't use so much that it lubes the brakes.
