If you know how to take the whole unit bearing and axle shaft out together, then ~$30 at a shop to swap the ujoints.
Take off brake caliper and hang it with a bungee
take axle nut off (large size)
Remove 4 6-point bolts on the backside of the knuckle that holds the unit bearing
it may require some creativity with the steering to provide some umpf on the bolts to push unit bearing out
Slide whole assembly out carefully supporting the axle shaft so as not to disturb the axle seal inside by the differential.
