I have recently started hearing a strange noise from the cobalt best description is it sounds like an airplane running. Does not change with direction always constant. Does seem to be getting louder as time goes on. I've checked tire wear balance front end alignment all OK. Does anyone have any idea of what this could be ?

Thanks

If you go around a curve on a high way and the noise gets worse, that will typically mean the hub on the side opposite the turn is the bad one. FOr instance, if you are going 50mph and the road starts to curve left and the noise gets worse, the the right hub is likely the bad one.
One of the best ways to test for a bad hub is to jack up on side of the front until the wheel is off the ground. Grab the top and bottom of the wheel and try to wiggle it back and forth. If you find more than little play, it is usually a bad hub on that side.
They are pretty easy to replace and if you have the tools and time an a little mechanical knowledge, it can be done in the driveway. There are plenty of Youtube videos on it.
