Wheel bearings are designed for longevity. Their life expectancy, based on metal fatigue, can usually be calculated if general operating conditions are known. Bearing failures not caused by normal material fatigue are called permanent failures. The causes can range from improper lubrication or incorrect mounting, to poor condition of the shaft housing or bearing surfaces.

Inspect the bearings for these improper wear conditions, and for:

A. pitting.
B. rust.
C. corrosion.
D. Excessive clearance(play)

If you find any of the above stated damage. The bearings should be replaced not adjusted. To service the wheel bearings, you'll need to repack the bearings and replace the grease seal.

There are a number of videos...
For RWD front hubs. (F250 will just have larger bolts.)

   Follow removal procedure in reverse order.
   

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

replace the bearing or wheel hub assembly.

REMOVAL & INSTALLATION 2wd Models NOTE: Refer to wheel bearing service and bearing preload adjustment procedures found in Section 1.

1. Raise the front of the truck and support it with safety stands. Remove the wheels.
2. Remove the brake caliper and suspend it with wire, out of the way. Remove the caliper torque plate if equipped.
3. Remove the dust cap and then remove the cotter pin, lock washer (if equipped) nut lock and nut.
4. Pull the hub/disc assembly off the spindle with the outer bearing. Don't let the bearing fall out.
5. Pry the inner oil seal out and remove the inner bearing. To install:
   
6. Clean and inspect the bearings and outer races.
7. Using a brass drift and a hammer, drive out the bearing outer race. Press a new one into position.
8. Pack the bearings with grease until it oozes out the other side. Coat the inside of the hub and cap with grease.
9. Position the inner bearing into the hub, coat the oil seal with grease and press it into the hub.
10. Press the hub assembly onto the spindle and install the outer bearing and thrust washer.
11. Install the hub nut. Turn the hub a few times to seat the bearings and then loosen the nut until there is 0mm axial play. Using a spring tension gauge, check that the preload (with new grease seal installed) is 2.2–6.4 lbs. (9.8–28.4N)
12. Install the lock-nut, new cotter pin and hub grease cap.
13. Install the brake torque plate. Install the brake caliper.
14. Install the wheels and lower the truck.

4wd Models The hub and bearing service procedures for a 4wd models are basically the same as those for a 2wd version, with the exception of removing the free running hub assembly and the bearing preload adjustment. Refer to Sections 1 and 7 for additional information. Adjust the preload after the wheel bearing is replaced or the front axle assembly is reassembled. BEARING PRELOAD ADJUSTMENT

1. Thoroughly clean all parts and pack the wheel bearings.
2. Apply grease to threaded portions of the spindle, grease seal lip and wheel hub.
3. Tighten the wheel bearing lock-nut with a socket and torque wrench to 58–72 ft. lbs. (78–98 Nm).
4. Rotate the hub in both directions a few times to seat the bearings. Loosen wheel bearing lock-nut.
5. Retighten the lock-nut to 0.4–1.1 ft. lbs. (0.5–1.5 Nm).
6. Turn wheel hub several times in both directions.
7. Retighten the lock-nut to 0.4–1.1 ft. lbs. (0.5–1.5 Nm). Fig. 1: Exploded view of the front axle assembly — 2wd models
   Fig. 2: Removing the bearing outer races
   Fig. 3: Packing the wheel bearing with grease
   Fig. 4: Pack the lip cavity of grease seal with grease
   Fig. 5: Exploded view of the front axle assembly — 4wd models
   
   
8. Measure wheel bearing axial end-play. The wheel bearing end-play specification is 0.
9. Install lock washer by tightening the lock-nut within 15–30 degrees.
10. Turn wheel hub several times in both directions. Wheel bearing should be seated correctly.
11. If necessary, measure wheel bearing preload. NOTE: Measure wheel bearing preload with a spring-type gauge; measure at wheel hub bolt, with tire removed. The hub assembly should rotate with 1.6–4.7 lbs. (0.73–2.13 kg) of pressure.
    

Make sure you remove all the rust from the spindle and rotor. Make sure the bearing races are all flush. Use a rubber mallet,not a hammer
to properly seat the rotor. Good luck.

1. Before servicing the vehicle, refer to the Precautions Section.
2. Raise and safely support the vehicle.
3. Support the front end.
4. Remove the wheel cover, if equipped.
5. Remove the grease cap.
   NOTE Check the wheel bearings for sufficient grease.
   
6. Remove the cotter pin and retaining washer. Back off the spindle nut. Discard the cotter pin.
7. Adjust the wheel bearings as follows:
   1. Tighten the spindle nut to 30 ft. lbs. (40 Nm) while rotating the brake disc clockwise to seat the wheel bearings.
   2. Back off the nut 2 full turns.
   3. While rotating the disc counterclockwise, tighten the nut to 17-24 ft. lbs. (23-34 Nm).
   4. Back off the spindle nut about 1 / 2 turn.
   5. Tighten the spindle nut to 17 inch lbs. (2 Nm).
   
   
8. Install the retaining washer so the castellations are aligned with the cotter pin hole. Install a new cotter pin.
9. Check the wheel and tire assembly for proper rotation, then install the grease cap. If the wheel still does not rotate properly, inspect and clean or replace the wheel bearings and cups.
10. Install the wheel cover, if equipped.
11. Lower the vehicle.
12. Road test the vehicle and check for proper operation.

To check the wheel bearing adjustment, raise the front of the vehicle. Grasp the tire at the sides, and alternately push inward and pull outward on the tire. If any looseness is felt, adjust the front wheel bearings as follows.

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove the hub cap from the hub.
3. Remove the cotter pin and the castellated nut.
4. While rotating the wheel, tighten the adjusting nut to 21 ft. lbs. (28 Nm) to seat the bearings.
5. Back off the adjusting nut until loose (120-180 degrees).
6. While rotating the wheel, tighten the adjusting nut to 18 inch lbs. (2Nm). Torque required to rotate the hub should be 18 inch lbs. (2 Nm).
7. Install the castellated nut and insert a new cotter pin.
8. Install the hub cap

what I do is put a glob of grease in the palm of my hand and push bearing down in to grease untill you see the grease come out of the bearing or you can go to your local parts store and get a bearing grease packer. also wipe spindal with a genorus glob and put grease in between bearing in rotor. To get to the bearings all you need to do is remove tire, center cap (outter grease seal) the silver cap in the center. the cotter pin, Nut, washer outter bearing then the rotor will slip off inner bearing is in rotor still being held in by inner grease seal take seal off replace with new one pack your bearings and reverse removal procedure when retightening nut do not make tight just snug the go another turn if you go to tight you will burn your bearings real fast.
