714,
To look at the wheel bearing, reomve the tire and use a flat blade screw driver to slowly pry betwwen the bearing shell and the hub.
You can work or use slight force to get the blade betwwen the hub and shell and then just continue to pry the bearing shell off. When you get it about 1/2 off you can grab the shell with some channel locks to remove it completely. Put a rag between the pliers and the shell to keep from marring the surface.
The bearing is held in placeby a collar that locks to the spindle with a 5mm allen bolt. Loosen the bolt then you can adjust the bearing or remove it.
To adjust it, turn the collar in with about 20 ft-lbs of torque, then back off the collar 1/8 of a turn. You want the disc brake rotor to still spin freely or with just a minor load.
Once you get that done, tighten the 5mm bolt and put the bearing shell back into place.
If you need new bearings you need to remove the race also, and unfortunately I have not checked into the procedure to remove the race.
