HI, For replace the front wheel bearing. on a toyota corolla 03
You need a hydrualic bench.
Because they goin pressed.
I recomend go to a repair shop, is not easy.
It's take about 2 hour to do. with the right tools.
Remove the wheel. Remove the ABS speed sensor if so equipped.
Unclamp the brake hose from the shock absorber, but do not disconnect the line.
Remove the brake caliper and hang it out of the way on a piece of stiff wire. Do not disconnect the brake line; do not allow the caliper to hang by the hose.
Remove the brake disc.
Place a dial indicator near the center of the axle hub, and check the backlash in the bearing shaft direction. Maximum is 0.0020 inch (0.05mm). If the backlash exceeds the maximum, replace the bearing.
Usiung a dial; indicator, check the deviation at the surface of the axle hub outside the hub bolt. Maximum is 0.0028 inch (0.07mm). If the deviation exceeds the maximum, replace the axle hub.
Install the disc and caliper. Tighten to 65 ft. lbs. (88 Nm).
Remove the cotter pin and install the wheel. Lower the vehicle to the ground.
Remove the lock nut cap. While depressing the brake pedal, remove the center axle nut.
Raise and support the vehicle again and remove the wheel, caliper and disc.
Loosen the 2 nuts on the lower side of the shock absorber. Do not remove the 2 nuts and bolts.
Remove the cotter pin and nut from the tie rod end.
Remove the tie rod end from the knuckle using a joint separator or equivalent.
Remove the bolt and 2 nuts holding the bottom of the ball joint to the control arm and separate the arm from the knuckle.
Remove the 2 nuts from the steering knuckle. Place a protective cover or shield over the CV boot on the driveshaft.
Using a plastic mallet, tap the driveshaft free of the hub assembly.
Remove the bolts and remove the axle hub assembly.
Clamp the knuckle in a vise with protected jaws.
Remove the dust deflector. Loosen the nut holding the ball joint to the knuckle. Use a ball joint separator tool or equivalent to loosen and remove the joint
Use a slide hammer/extractor to remove the outer oil seal.
Remove the snapring.
Using a hub puller and pilot tools or equivalents, pull the axle hub from the knuckle.
Remove the brake splash shield (3 bolts).
Use a split plate bearing remover, puller pilot and a shop press, remove the inner bearing race from the hub.
Remove the inner oil seal with the same tools used to remove the outer seal.
To install:
Place the inner race in the bearing. Support the knuckle and use an axle hub remover with a plastic mallet to drive out the bearing.
Clean and inspect all parts but do not wash or clean the wheel bearing; it cannot be repacked. If the bearing is damaged or noisy, it must be replaced.
Press a new bearing race into the steering knuckle using a bearing driver of the correct size.
Place a new bearing inner race on the hub bearing.
Insert the side lip of a new oil seal into the seal installer and drive the oil seal into the steering knuckle.
Apply multi-purpose grease to the oil seal lip.
Apply sealer to the brake splash shield and install the shield.
Use a hub installer to press the hub into the steering knuckle.
Install a new snapring into the hub.
Using a seal installer of the correct size, install a new outer oil seal into the steering knuckle.
Apply multi-purpose grease to the seal surfaces which will contact the driveshaft.
Support the knuckle and drive in a new dust deflector.
Install the ball joint into the knuckle and tighten the nut to 105 ft. lbs. (142). Install NEW cotter pin.
Temporarily install the hub assembly to the lower control arm and fit the driveaxle into the hub.
Install the knuckle to strut bolts, then attach the tie rod end to the knuckle.
Tighten the strut bracket nuts to 203 ft. lbs. (275 Nm) and tighten the tie rod end nut to 36 ft. lbs. (49 Nm). Install the NEW cotter pin.
Connect the ball joint to the lower control arm and tighten the nuts to 105 ft. lbs. (142 Nm).
Install the brake disc.
Attach the brake caliper to the knuckle and tighten the bolts to 65 ft. lbs. (88 Nm).
Install the center nut and washer on the drive axle.
Install the ABS speed sensor if so equipped. Install the wheel
Lower the car to the ground.
Tighten the wheel nuts to 76 ft. lbs. (103 Nm). Tighten the hub nut while depressing the brake pedal to 137 ft. lbs. (186 Nm) on 1988-91 models and 152 ft. lbs. (206 Nm) on 1992-97 models. Install the cap and cotter pin.
Remove the protective cover from the CV boot. Check front wheel alignment
Diagnosing the bearings can be tricky depending on severity of wear. Typically - drone noise at highway speeds, squeeling, clicking or grinding noises at low speeds that reduce during braking, or pull off the wheel and brake assembly and check the bearing for slack or smoothness of rotation by hand. While doing this, check the brake assembly thoroughly - generally a more likely culprit of wheel noise.
Wheel bearing replacement is not for the novice backyard mech. - you will need pullers, press, etc. If you can get a rebuilt assembly - much easier.

possible a loose front wheel bearing or a failed front wheel bearing
the abs light sensor is probably touching the rotor
tack it back to the shop that did the job as there is a problem in the assembly of the unit.
remove caliper, rotor, caliper bracket, lower ball joint shaft and two strut bolts. remove bearing housing and any snap rings. remove old bearing. replace and repeat in reverse. watch the abs sensor! costly if damaged. This is not for beginners...
Rather than just the bearing, I suggest a new half shaft as the bearings and ABS tone wheel are already assembled. These Escapes are notorious for cracking the tone wheel setting off a code and then disabling the AWD system. So for a very few dollars more than it would take to disassemble the shaft , install bearings and tone wheel just get a new one.
A couple of ideas for you.
1) When the tires were replaced, in the process of doing that , the car was lifted off the ground somehow, causing the front wheels to "drop".
Please check most carefully the plastic liners ( there are several) that surround the wheels, and see if one or some are rubbing the tires whilst you are driving down the lane.
2) If that is not the problem, jack up one front wheel at a time, and block or "scotch" the other three, and start the engine, and engage the transmission, and see if you might have a bad wheel bearing. ( it should be noisy).
You may choose, ever so carefully, to use a "mechanic's stethoscope", which is a long handled screwdriver, wherein you put the wood handle to your ear, and the metal tip at various places under the car to try to identify the source of the noise.
God bless your efforts.
