Front Hub Swap

[Ewr101]

Forgive me if this has been gone over before but I don't know all the correct terminology to even do a search for the info. I have a 72 2wd Blazer and was wondering if anyone had swapped out the spindle and brake rotor to a more modern one? One where the brake rotor could be easily replaced and the wheel studs were part of the hub. This would save maintenance and replacement on the front wheels bearing and no greasy messes. Hope I was able to convey what I'm asking so it's understandable. Thanks for any info in advance.
