Just replace both front ones. The other one is gonna go bad eventually.
i'd put it on jackstands withe the wheels off the ground and have someone spin it up. slide under with an automotive stethoscope and listen to each wheel bearing. I've had a few that you're 100% sure its one side while driving and find its the other once its in the air. never hurts to double check... save having to buy a customer a new wheel bearing cause you screwed up.
