Do I need to remove hub to replace front rotors on 97 f250 4x4 diesel?

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.

1. Separate cap assembly from hub body by removing the three Torx® head capscrews.
   
   
   
   
   
   
   
   
   

1. Remove the lock ring seated in the groove of the front disc brake hub and rotor (1102).
   
   
   
   
   

1. Remove the hub body assembly from the front disc brake hub and rotor. If the body is difficult to remove, install two capscrews and pull the body assembly out of the front disc brake hub and rotor.
   
   
   
   
   

Installation

1. NOTE: Do not pack the hublock body assembly or cap with grease. Excessive grease can cause excessive dialing effort and hub failure.
   
   Follow removal procedure in reverse order.
   

1. Tighten three Torx® head capscrews to 4-6 Nm (35-53 lb-in).
   

No, but I would replace the rotors. Turning them usually winds up getting them warped as soon as they heat up and/or you hit a puddle of water..also, you will need a torque wrench and standard automotive tools, Jack and stands and a vice..

1 Place the Transfer shift in the 2H position.
Raise and support the front of the vehicle safely on jackstands.
2 Remove the wheel and tire assembly.
3 Loosen the hub to rotor retainer bolts.
4 Remove the brake caliper mounting bolts and carefully remove the caliper (along with the brake pads) from the rotor. Do not disconnect the brake line. 5 Secure the caliper out of the way with the flexible line still connected.

Once the hub/rotor is removed from the vehicle the wheel bearings may be cleaned and repacked or the bearings and races may be replaced. For more information, please refer to the wheel bearing procedures in General Information & Maintenance of this manual.

6 Remove the hub nut using hub wrench J-29020-A or equivalent.
7 Remove the hub cap assembly retainer bolts.
8 Remove the spindle nut, washers, and other components. Remove the hub/rotor, being careful not to drop the outer wheel bearings. As the hub/rotor is pulled forward, the outer wheel bearings will often fall forward.
9 Once the hub/rotor is removed, remove the retainer bolts securing the rotor and hub together. Inspect the hub and replace if needed.

To install:
1 With the rotor secured in a vise, attach the wheel hub to the rotor using the retainer bolts. Tighten the bolts to 47-58 ft. lbs. (61-75 Nm). Apply 2.12 oz. (60 gm) of grease to the hub before installing.
2 Carefully install the wheel hub/rotor over the spindle.
3 Install the bearings washers and other components. 4 Position the lock washer so the hub cap assembly bolt holes line up properly.
5 Install the spindle washer and nut and secure using hub wrench J-29020-A or equivalent. Preload the bearing to 3.31 lbs. (1.5 kg).
6 Install the inner cam and any shims. Install the hub cap assembly and secure in place with retainer bolts. 7 Tighten grade M8 bolts to 17-22 ft. lbs. (22-29 Nm), tighten grade M10 bolts to 40-47 ft. lbs. (52-61 Nm).
8 Install the brake caliper.
9 Install the tire and wheel assembly.
10 Remove the supports and carefully lower the vehicle.

Removal & Installation

1. Remove 2/3of the brake fluid from the master cylinder.
   
2. Raise and support the vehicle.
   
3. Remove the tire and wheel assembly.
   
4. Remove the front wheel hub extension (dual wheel vehicles only).
   
   • Insert a drift or large screwdriver through the brake caliper into one of the brake rotor vanes in order to prevent the rotor from turning.
     
   • Mark the relationship of the front wheel hub extension to the hub
     
   • Remove the front wheel hub extension bolts
     
   • Remove the front wheel hub extension from the vehicle. It may be necessary to tap around the perimeter of the hub extension with a rubber mallet to loosen it from the hub
     
5. Mark the relationship of the rotor to the hub.
   
6. Remove the caliper and mounting bracket as an assembly.
   
7. Hang the caliper and the mounting bracket assembly from the suspension using mechanics wire.
   
8. Remove the rotor.
   
9. If the rotor is difficult to remove due to corrosion in the hub area use the following procedure to remove the rotor (25 series only).
   
   • Clean all the surface areas and the threaded holes of contamination
     
   • Generously apply penetrating oil or the equivalent to the hub/rotor area
     
   • Insert (2) M10 x 1.5 bolts (jack screws) into the threaded holes of the rotor
     
   • Tighten both bolts evenly to force the rotor from the hub.
     

To install:

1. Clean all rust and contaminants from the both side of the rotor and the hub flange.
   NOTE If the rotor was removed using the jack screw method you must ensure that the hub flange is free of nicks or marks caused by this procedure. Remove all raised nicks or marks before installing the rotor.
   
   
2. Install the rotor.
   
3. Install the caliper and the mounting bracket as an assembly.
   
4. Install the tire and wheel assembly.
   
5. Remove the safety stands.
   
6. Lower the vehicle.
   

Hub and Bearing Assembly
CAUTION: Do not begin this removal procedure unless the following parts are available:

• A new front axle wheel hub retainer (3B477) (Step 1).
• A new inboard halfshaft joint stub shaft circlip.

Once removed, these parts must not be reused during assembly. Their torque holding ability or retention capability is diminished during removal.
Removal

1. Turn ignition switch to the OFF position and place the steering column in the unlock position.
   

1. CAUTION: Discard the front axle wheel hub retainer. It is a torque prevailing design and cannot be reused. If loosened, the retainer must be removed and a new one installed.

To remove that hub you will destroy the bearing. Because you have to remove it with a slide hammer. It is not necessary to remove the hub to change the studs. Remove the caliper, caliper bridge and rotor. Using a hammer simply knock out the stud or studs you want to replace. Put new stud in and using a sleeve that has a bigger diameter than the stud (I use a big nut, like the one on the axle) put big nut over stud and screw lug nut on stud and tighten until head of stud is flush with hub. Re-install rotor, caliper bridge and caliper. Hope this helps.

Hyundai Tiburon 96-01 uses a outer hub system. To replace front rotors. You'll need front bearings as well. The bearing and hub will need to be pressed out of the spindal. Then replacement of bearing will need to be pressed in. From a shop.Or they can use a slide hammer to remove ,but damages the bearing. Best to buy bearing and have cash for an alignment job too.Then replace front rotors. Rotor and hub install is ez after you get bearing pressed.Rear rotor and bearing are bolt on though.

Your emergency break shoes might be holding you up from geeting the hub off there inside the hub, i think on the back side there should be a slot to get a ajustment tool in there to back them off. If not a big hammer is in order there also might be clips on the wheel studs from the factory. No you don't have to remove the axel. Your the best judge of what needs to be replaced your there, but i would say the ovious rotor, caliper, break pads, and maybe emergency break shoes, maybe backing plate.

The rotor and hub assembly are held together by the studs,you must first remove the 4-wheel drive hub assembly,then the wheel bearing nuts,and pull the hub and rotor off as a unit. Next lay it(back down) on a piece of wood, using a drift punch drive the studs out. Turn it over ,lay it(face down) on a block of wood, line the new stud splines up with the grooves in the hub and drive them in with the punch and reassemble. A set of dentist style picks will be helpful with the clip in the 4wd hub and a 4 lug 4wd nut wrench will be needed.
