84 cj-7 axles with 456 but axle bearings are bad

I have axles out of a cj7 the axles were bad when we pulled them so we swapped them with a differnt set up.They are geared with 456s but only good for gears and the front is good for gears plus the hubs asking 250 for the set perfect for a regearing or rebuilding if your doing a direct swap
