Your right the most common problem that makes a humming sound is the hub bearings, these will get louder the longer it is ran so I recommend that she at least takes it to her favorite shop and have it checked out, if it is the bearings they should be replaced in pairs cause as sure as you replace one it isn't long before the other one is howling.

I concur with my esteemed colleagues. The good news is if it's bearings it's not a safety issue, nor is it an emergency to repair. Other than being annoying they can go for months, even years. And while it is true that doing them in pairs is nice to do, they can most certainly be done one at a time if money is tight. I find the left one usually goes first, but your experience may differ. If she plans to keep the car buy the good American made (expensive) ones. The cheap import ones often last less than a year and have to be done again. If the car's going away soon the cheapie will do fine.
