I can not get the rotor to seperate from the hub on the front wheel. Any advice would be helpful. Thanks

it is a one peace unit all you had to to is re place the barrings and check the races if the races are bad you need to buy the rotor and hub

once you remove brake and hub assembly place on clean workbench with the lug bolts up, then with a center punch and hammer place punch on center of lug and knock it out would reccomend putting the lug nuts on lugstuds till they are flush in order to prevent damage to threads of studs.this will allow you to seperate rotor from hub.

Are you talking about the front rotors? The hub and rotor are one assembly and do not seperate on that truck. If you need to replace one part, the replacement part will have the hub and rotor together.

The reason you're getting mixed info from parts stores is because it comes both ways.
Look at the following to determine which one you have, 4 wheel disc brakes (floating front rotors) or rear drum brake model (except 4 wheel disc brakes):
Brake Disc (Rotor) REMOVAL & INSTALLATION Except F-Super Duty with 4-Wheel Disc Brakes Fig. 1: Secure the caliper so there is no tension on the brake hose

1. Jack up the front of the truck and support it with jackstands. Remove the front wheel.
2. Remove the caliper assembly and support it on the frame with a piece of wire (or something equally secure) without disconnecting the brake fluid hose.
3. Remove the hub and rotor assembly.
4. Install the rotor in the reverse order of removal, and adjust the wheel bearing as outlined in Section 1.

F-Super Duty with 4-Wheel Disc Brakes The hub and rotor are individual pieces, allowing the rotor to be replaced independently. The front and rear rotors are the same and are attached with 10 bolts and washers. The bolts are tightened a little at a time, in a crisscross fashion, to an ultimate torque of 74–89 ft. lbs. (100–121 Nm).

Hello, the front wheel bearing is not to be serviced seperately, it comes as a complete unit with the front hub and the ABS sensor ring.

so there is no need to press the bearing into the hub.

Just remove the driveshafts, the rotors and calibers and replace the hub.

not sure on this ,look carefully because it might be a complete unit ,if their isnt two screws on the front of the brake disk then its a complete unit ,Have you bought the disks yet?? check them out if you have to look for the answer

its a pressed in bearing,i would recommend u to have it done by mec.but here goes,take wheel off,undo cv axle center bolt,undo brakes,calyper,disc rotor,undo tie rod,lower control arm ball joint,undo strut from steer.knuckle,slide knuckle off cv shaft.at this point u can take steer.knuckle to machine shop to seperate and install hub and new bearing or u can have fun taping out hub and bearing and theres a good chance that bearing will seperate when taping out hub,youll need a puller to take bear.part off hub,then taping them back in without damaging bearing.u will need ball joint seperator,socket for cv bolt,2 jaw puller.

they are manufacturered in one piece, i would say it's broken and needs replacing

If you have 6 bolts going around the center (manual lock in/lock out) hub, you are going to be there a while. The center hub needs to come off, and ALL of the internal wheel bearings need to come out. The whole locking hub must be removed in order get the rotor off. This is NOT an easy job, and you need a special tool to loosen/tightem the wheel bearings. Figure 2 hrs per side if you have all of the proper tools & skill level.

Take it apart in the order you see you need some snap ring pliers for item #4 . Take off #7 and the rest of the parts. Seperate the hubs from the Rotors (it may need to go to a machine shop fort this operation) When you reassemble make sure that one of the holes in # 7 line up perfectly with a threaded hole in #8
Make sure you get the wheel bearings tight but not too tight and Grease them properly with the prooper Lube recommeded by Izuzu.
Hand TORQUE the wheel lug nuts as Izuzu has a BIG BIG Problem with wheel lugs stripping USE A TORQUE WRENC
