Going to replace the front rotors and pads on my '93 F-250. Couple of questions since this looks more complicated than more modern sealed hubs like I'm used to...

Do I need to buy the rotor/hub assembly or can I knock the studs out of the old rotor and reuse the hub?

What else should I be replacing as long as I've got this apart? It's just a junk tow-pig for my boat that I put about 250miles/year on, but I'd rather replace things that are cheap and (probably) bad on a truck with 240k miles on it. Thoughts?

 

2wds you will replace the Whole rotor/hub assem

4wds you will remove the rotor/hub assem and knock the studs out the remove the rotor

 

What brad said and at that mileage id toss it a new set of bearings...
