Hi. I have a question about wheel bearings. I just bought a 06 saturn vue and it humms loudly when i
drive, in the front drivers side. I think the wheel bearing needs to be changed. Since its coming from that 1 side, should I change the other side as well? I dont hear it on the passenger side

Some new cars have wheel bearings that are sealed that are good for the life of the car until they break. However, some cars still use standard bearings that need to be cleaned and repacked with fresh grease every so often.
