Items you will need
2 Jack stands
Socket set (assorted sizes)
Large adjustable wrench
Replacement inner and outer bearings
2 Replacement grease seals
Block of wood
2 Replacement cotter pins
The front wheel bearings on your Ford F250 consist of an inner bearing and an outer bearing mounted to each side of the wheel hub. The bearings are packed with grease, and allow the wheel and tire assembly, which is bolted to the hub, to spin freely. A worn-out wheel bearing may create too much “play,” or side-to-side movement, in the wheel and tire assembly. The bearings may also wear prematurely if they are not repacked with grease periodically.
Jack the front of the vehicle up until the wheels are off the ground using a floor jack. Place jack stands under the axle beam on each side of the truck. Lower the floor jack. Remove the front wheel lug nuts with a lug wrench turned in a counterclockwise direction. Remove the wheels. Place the lug nuts and wheels aside.
Remove the brake caliper bracket bolts on the rear of the caliper with a socket and ratchet turned in a counterclockwise direction. Lift the caliper straight up from the brake rotor. Use a piece of wire and hang the caliper onto the spring in the wheel well, being careful not to stretch the rubber brake line attached to the caliper.
Pry off the dust cap from the center of the combination wheel hub/disc brake rotor with a flat-blade screwdriver. Remove the cotter pin from the hole at the end of the steering spindle (revealed after removing the dust cap) with a pair of pliers. Remove the holding nut from the spindle with a large adjustable wrench turned in a counterclockwise direction.
Pull the wheel hub/disc brake rotor straight off of the steering spindle, being aware that the outer wheel bearing and washer will fall out to the ground. Place the hub upside down on a work surface. Pry the circular grease seal out of the center of the hub with a flat-blade screwdriver and pull out the outer wheel bearing. Clean the grease from the hub thoroughly with solvent and a parts brush.
Pack your new inner and outer wheel bearings by placing a large dab of axle grease in your palm. Push the edge of the bearing into the grease with your other hand until grease comes out through the rollers at the top of the bearing. Repeat this step for the inner and outer bearings.
Place the outer bearing into the back side of the hub with the tapered side facing inwards. Carefully push a new grease seal onto the hub using a block of wood and a hammer. Push the hub assembly onto the wheel spindle. Push the inner bearing onto the spindle with the tapered side facing inward. Push the washer onto the spindle. Thread the nut onto the spindle and tighten to 18 feet pounds with a torque wrench. Push a new cotter pin through the small hole at the end of the spindle, and bend it over with a pair of pliers to keep it from backing out. Push the dust cap back into place until it is fully seated.
Unhook the wire from the brake caliper and slide it back over the disc brake rotor. Replace the original holding bolts, and tighten with a socket and ratchet in a clockwise direction.
Repeat steps 2 through 7 for the other side of the front of the vehicle. Replace the wheels and tighten the lug nuts. Raise the front of the truck with a floor jack and remove the jack stands. Lower the truck.
