If you can remove wheel bearings and replace that's simple enough.

King pins could still be done mostly by you.
If they come out then only need to take spindles to the machine shop to ream or hone bushings.
If they don't come out you can remove axle with spindles attached so they can first press the pins out, then fit bushings and ream/hone.

Only difference in a medium duty truck and the smaller ones is weight/size of the parts, they go together the same.
