Is this a front left wheel Bearing giving up or the right ??
Check to see if you have a dragging brake caliper. One of the quick and dirty ways of DXing this problem is as you are turning and it starts to make the noise hit the brakes and see if the sound and vibration goes away or changes in anyway. If this happens pull the calipers and check for a seized caliper piston, and make sure the caliber it's self is floating. The inside caliper has the piston and when braking pulls the other half of the brake caliper and brake pad into the rotor if the caliper is frozen in place it tends to drag. The noise and vibration happens when the wheel turns into this dragging outside caliper. or on the opposite side into a seized inside caliper. Oh yes and I almost forgot the brake pad also comes with a wear indicator, that makes noise, and vibrates when the pad wears down and this piece of metal starts to scrape on the rotor. This wear indicator tends to be left off of subsequent brake jobs if the mechanic doing the job likes to cut corners.
125,000 miles is well with in the wear cycle of a well greased wheel bearing especially in a 2 wheel drive front end, that is as long as you aren't doing daily drives down an ocean front hunting for a bathing suit optional beach.
