If your talking about the lug studs, just tap them out and tap new ones in.
Even if you need to remove the hub from the carrier.
Just unbolt the axle and let it lay down, remove the large nut that holds the 4 bolt cup on. A 1/2" impact just buzzes it off, no need for a bar holder. Then remove the cup, get a deadblow hammer and tap the hub striaght out. It will come out pretty easy.
Then tap all the old studs out of the hub plate and tap new one in.
Add some more grease and reassemble.
Super easy.
