It's more likely that you have an issue with the needle berring inside the wheel berring assembly... was just checking that on my red truck last night. Needle berrings don't get greased, they rust/freeze up, and score the stub axle. I put a new needle berring in mine, but it's scored the axle, and it needs replaced.
To get to the needle berring, you have to remove the tire, the brake caliper bracket, the lock out hub, and the unit berring. A 21mm socket will get the caliper bracket off, and the unit berring out, needle nose pliers and snap ring pliers will get the hub off. Not too hard, just hard to break the hub and caliper bolts lose... my air impact wouldn't do it, I had a cheater pipe on a breaker bar to losen them. Then they spun out with the impact gun easy...
