Has anyone ever replaced the rotor on the front of a 2X4 dually? I'm going to have mine turned this weekend and I need to know how to take them off.

 

Think the rotor and hub are replaced together

 

I'm pretty sure you take the axle out. It's really not that big a deal, just ake off the wheels, undo the 6 bolts holding the axle in, and then use either the "special" tool, or a pair of vise grips and unscrew the axle. Then just put back together the reverse of removal. You do have a manual for torques and stuff right?

 

Almost like any other rear wheel drive except the hub and rotor is one piece. I had a heck of a time getting the grease cup back on. Good luck on turning them, I just replaced mine.

 

I looked at the picture at the parts house program that I use and it appears to be a large spindle bearing underneath the hub cap.
To gain access to it, remove the center cap and (I'm guessing) it will be like boat trailer bearings. Remove the cotter pin, unscrew the nut and pull it all off.
The caliper will have to be removed first.
And be careful of the ABS sensor. Remove it before you pull the rotor off. Install it after you get it back on.
