Question about Ford E-150
SOURCE: replace front wheel bearings
The bearings in your car are pressed into a hub. If the part is available as an assembly, it can be replaced that way. Generally on a front drive car:
Remove wheels and brake calipers
If it is pressed in: remove the rotors, disconnect the drive shafts and remove the steering knuckle. Then the old bearing is pressed out and the new one pressed in with a machine shop press. If the bearing is part of the hub, that will be unbolted and the new one swapped.
On a scale of 1-10 difficulty, Id rate it a strong 7

Remove the wheel, remove the hub nut, remove the brake caliper and rotor, put your socket and extension through the hub flange onto the bearing retainer bolts, undo them, release the abs sensor connector if it has it, remove the bearing and hub flange as an assembly, put the new one on and go backwards from here. Torque the hub nut to 180 ft/lbs, your done.

The bearings on the wheels has to be installed one way only, the rotor ring is built into the bearing and if installed the wrong way round the sensor cant pick up the wheel speed causing the ligt to be switched on in the cluster. The diagnostic equipment should pick this up as a fault once the car has been driven, it will see the sensor when you do the diagnostic if the car is standing still but once the car is moving and no signal is send from that wheel it would register a fault into the memory of the PCM that you would be able to retrieve later.
There is a way for you to test the sensor yourself by using a multimeter set on volts, you jack the vehicle up at that wheel, install a vehicle stand to support the vehicle to be safe, disconect the wheel speed sensor and probe the two wires into the sensor, spin the wheel by hand and a small amount of current will be produced meaning the the sensor is working and the wheel bearing is installed the correct way, you can also do a continuaty test on the sensor by switching the multimeter onto ohms, but be very carefull, if this sensor has three wires you cant do the continuaty test because of the integrated circuit in the sensor, the three wire sensors opperate on a voltage from 5Volt and it would be destroyed by the multimeter opperating on 9Volt.
If the continuaty test passes and the bearing is installed the correct way, the most comon fault would be a break in the wiring leading to the PCM
Hope this will be helpfull.

The front wheel bearings are sealed units, and must be replaced with the entire hub assembly. They do not need periodic cleaning/replacing as they did in the old days, if they are not making noise do not bother with them.

Too long to write out but here are the essentials: Remove the center bolt that holds the front axle into the hub. (usually very tight...around 150 lbs torque....sometimes helps to have a shop loosen it and then put it back tight but less tight so you can remove it when you get it home)
Remove the caliper and rotor. Remove the three bolts that hold the bearing hub to the steering knuckle.
Soak the parting line between the hub and knuckle with wd40 or other solvent and use a chisel on alternating sides to work the hub free.
Clean and lube the cavity where the hub goes through the knuckle and reverse the process to re-install.
