should I change front bearing hub "while im in there"?

Since I got my late 99 f250 about a month ago I have been trying to get the esof hubs to work. When I got the truck, the passenger front had a wasted needle bearing, and badly leaking knuckle seal, so I replaced the knuckle seal, wheel bearing, stub axle, u-joint, yellow and black o-ring.

The hubs now lock right away, but do not unlock without turning the dial a couple times (hubs have been completely cleaned and lubed twice now). A vac test determined that the passenger side now holds vaccum as it should, but driver side has a slow-ish leak. The needle bearing and wheel bearing seems fine, but I am planning on doing the knuckle seal, needle bearing service and o-rings on driver side to see if I can stop the leak completely.

My question is this: should I replace the whole wheel bearing hub while I am in there? I have no idea how old it is, the truck has 103k, doesnt seem like any water or mud has gotten into this side, so maybe I should just service the needle bearing and put it back in.
What do you guys think, replace it, or leave it there and let it fail on its own time (which could be next week )?

I'd just replace the inner needle bearing ($15) while you're in there and be done with it.

I think, being on the "outside" of the Knuckle Seal, you could wait until the hub actually went bad before replacing it. On the "inside" of that seal, I'm with-ya, I'd replace stuff good OR bad once I was in there.

The hubs easy to change later if needed (save yourself some ca$h)
