What is involved in replacing front bearings in a 2000 Chevy S-10 Blazer 4x4?

in replacing the front bearings you need to replace the entire hub assembly. approx $300 remove the brake calaiper and mount, and the rotor. Remove the star screws holing the hub in place and remove the hub. *the hub may need to be persuaded with a hammer* Mine certainly did. be careful not to damage the 4x4 actuator wire. Replace the new hub over the groved axle and put everything back together. good luck
