half shafts, cv joints, meh, its all the same.
Replace the wheel bearings and the front axle shafts (they aren't rebuildable). Might as well do both while you are in there. On the newer trucks there is no locking hubs, your axleshafts always spin, the chevy trucks have an axleshaft that uses a cv joint that is like a toyota birfield joint, its kinda hard to explain, but when the rubber boots rip and road grime gets in there they get noisey. They don't tend to click like a FWD cars do....
take off the wheel, caliper, rotor, wheel bearing, shafts, replace.
Have a 36mm socket handy, you will need it to pull the nut off the axle shaft that holds the wheel bearing in place.
