You may want to have the slightly oversized lower ball joints, along with the standard size ones, in case the holes they fit into are worn. You can always return the size you didn't use. You should also check control arm bushings, tie rod ends, upper ball joints also. You can do the job once, if the other parts are worn. Pitman arm and idler arms wear fast on these vehicles, shake the wheels, check them for wear, had to replace mine at 75k.
