sould be standard left to loosen,, make sure you soak it with PB blaster or Kroil,, I've spun the nuts, before(plow trucks) and had to buy the stub shaft(dealer only $$$) and new U joints,, Keep soaking it!!! Hub bearings are pricey also,, good luck,, You will have to use the jaws to pull it off, and the bolts on the back side, soak those,, I ve separated the hubs before, and then i ve had some come off easy,, Good luck,, total fix $350-$1200 per side. keep soaking, is all i'm saying...

Hub & bearing should be one assy, is that what your looking at?
3 bolts behind hub, to remove, done?

sounds like the rotor is stuck on the hub. Try beating it with a hammer you dont have to take the 4 bolts off they remove the wheel bearing. Axle doesn't have to be touched as well. After you remove the caliper and bracket the rotor should fall off.

4x4 has 3 bolts in back of knuckle take them loose and tap on them to force the hub out of the knuckle

Here is the easiest way . take a 14mm socket and extentsion and place it on the bolts and place againt your axle tube and start your truck and turn your wheel against it instead of pounding you will use your powersteering like a press to get your hub out its quicker and less strenous than pounding on the bolts ive done this many times i even made a extentsion for it i use a 14mm 1/2 drive shallow socket and a extension thats about 4 inches long i know im posting late on this one but if it helps anyone out then great
