Hello, it is getting to be that time where my front brakes are due to be changed. My question is - is the rotor and hub a single unit or can I just replace the rotor?
Thanks in advance

 

I use an on vehicle brake lathe to turn the rotors so I had to look it up in the parts "book"
Hub and rotor are listed as a unit!

 

Rotors are "slip off" style for 1500 and cast into hub on 2500 and 3500. They are really heavy and require a 14mm 12-point socket to remove from the back side. You will also need a HUGE socket-forget what size- to get the axle nut off, it is MEGA tight. Not really a quick driveway job, it will probably take you a day in the driveway IF you have all the right tools.
