How to Replace a Ford Focus Wheel Bearingby John Rose
The wheel bearing is a self-contained unit on the wheel of the Ford Focus. This means the bearing doesn't get lubricated during the normal grease and lube routine because it is a sealed bearing. While it doesn't happen very often, sometimes a bearings goes bad and you need to replace it. You can save a great deal of money by taking care of the repair in your own driveway or garage.
Park the car on a level surface and place the wheel chocks behind the rear wheels. Loosen the center nut on the wheel axle using a socket and ratchet, but do not remove it yet.
Open the engine compartment and loosen the center nut on the strut shaft. Back it off about 5 turns. Now jack up the car using the automobile jack.
Place a jack stand under the frame near the jacking point and raise the jack stand as close as possible to the frame of the car. Remove the wheel using the lug wrench.
Remove the hub retainer nut by twisting it off the axle by hand, then remove the brake caliper using a ratchet and the proper size socket. The caliper guide pins come out from the backside of the caliper. Secure the caliper to the strut to keep it from hanging loosely.
Disconnect the tie-rod end and lower ball joint by pulling out the cotter pins using the pliers, then using a socket and ratchet to remove the nuts.
Separate the wheel hub from the half shaft using the puller. Remove the pinch bolt from the knuckle using a socket and ratchet.
Release the wheel knuckle using the pry bar to free it, then remove the wheel hub and outer bearing race using the bearing puller. Pull the bearing inner ring with the bearing puller.
Remove the snap ring from the knuckle using the pliers. Remove the bearing outer ring from the wheel knuckle.
Press the new bearing into the wheel knuckle using a press tool and then reinstall the snap ring.
Press the hub into the wheel bearing using the press tool. Draw the stub shaft into the wheel hub using the half shaft installer tool.
Reinstall the steering knuckle and tighten the pinch bolt to 66 ft pounds using the torque wrench.
Reinstall the lower ball joint and tighten the pinch bolt to 37 ft pounds, then reconnect the tie-rod end and tighten the nut to 35 ft pounds.
Reattach the brake caliper using a socket and ratchet, then screw the hub nut on the shaft. Tighten it with the torque wrench to 232 ft pounds.
Reattach the wheel to the car and remove the jack stand. Lower the car to the ground.
Tighten the center strut nut inside the engine compartment using the torque wrench and tighten it to 35 ft pounds.
