Wheel Bearing - is this normal?

[OnyxAlero]

I just replaced the passenger side front wheel bearing last week. Car sounded great (made no wheel noise) for a few days. Now it is making the wheel bearing noise again, but this time it sounds like it is coming from the driver's side. Is it normal for the bearings to go bad around the same time?

Thanks for any advice. Just not looking forward to replacing another wheel bearing due to problems with removing the last one. The threads on the last one were defective from the factory and caused the bolts to be super tight. We had to cut them off and I am fearing the same with the other side.
