2005 Ford Escape how to replace front wheel bearings?

I have a 2002 Escape and have changed my bearings. The front wheel bearings on the Escape are simple cartridge bearings, or Gen1 bearings, that are pressed onto the hub and knuckle. They are not so simple to replace. Unless you have the experience and tools, you'll need to take it to the dealer or a shop.

You will need a press and the correct press tools.
The knuckle/hub assembly needs to be removed from the vehicle.

Here's the short version:
Remove the tire/wheel.
Remove the brake caliper w/ bracket.
Remove rotor.
Remove the ABS sensor.
Remove axle nut and press the axle inwards, until loose. (sometimes easy, usual needs special tool).
Remove the strut bolts, tie rod, and the lower ball joint from the knuckle/hub assembly. Each of these connections can have it's issues.
Press the hub out of the assembly. One half of the inner race will be stuck on the hub. Use a bearing splitter to remove that half.
Remove the snap ring from the knuckle.
Press the rest of the bearing from the knuckle.
Press the new bearing into the knuckle. Press on the outer race only!
Snap ring.
Make sure the dust sheild is still in place.
Press the hub into the bearing. The bearing must be supported on the inner race only!
The point is that you must not press thru the balls in the bearing. That can cause the bearing to get brinnelled.... not good.
Reassemble the knuckle on the vehicle in reverse order. I like to put a little grease on the axle spline. The axle spline has a little helix on it... about half a degree. It's supposed to be a tight fit. The torque on the axle nut is 300Nm (about 220ft-lbs?). This torque is very, very important. It is needed to keep the bearing together and at the correct preload, so use a big torque wrench.

...or you can take it to the dealer.

Good luck.
