Started the car this morning and started hearing a humming sound (it was perfectly fine last night). Sounds like it was coming from the front passenger side. Does not go away, you can hear it mostly when the car is stopped, sound of the car/driving masks the hum when moving. Anyone know what the issue is? Read something about hub bearings that seemed to match the issue, any other possibilities?

Also wanted to ask this, my car is parked outside and I start my days early when it is coldest in the morning. Is this particularly bad for the car? Thanks.
