Much easier. It's a straightforward job, if that is indeed the problem.
I haven't looked specifically but, if it's like every other American made since Ben Hur rode chariot it's pretty easy.
Pull the wheel, pull the caliper and hang it out of the way, pop the dust cap, undo the spindle nut and pull the outer bearing and rotor, pop/pry the back bearing out, pack the new ones with grease and put them in, torque the spindle nut til you get drag and back off a quarter turn and put everything back on. Job done.
