10 minutes work?
It'll take an hour or two total to press the king pins out, clean all the grease off everything, remove and replace bushings, and hone or ream the bushings to size. Then who reassembles it, I'd guess you can do that without any trouble.
Around here NAPA would do the whole job. However to save some money I'd only let them press the king pins out if stuck and then clean the parts. Then I would remove and replace bushings and take spindles and pins back to NAPA for honing to size.
