When I hit a curb I didn't change my bearings, and once the bearings broke and ****ed up my spindle I had to replace the entire lower suspension with a junk yard unit, because the spindle is a PITA to remove from kingpins/balljoints.(1984 Ranger BTW)
Seriously have your bearings looked at, if you can't immediately look at them, then wait until you can get time with whoever, but you most definitely need to look at those bearings soon, or sell the truck.
Even a local shop could give you a reasonable quote, this isn't rocket/nuclear/intelligence science.
