Just noticed last week that my left rear wheel is humming when I get up to speed around 30mph and gets worse as I get up to 70mph. I have also noticed in the last few weeks that my brakes are starting to squeak. Coud this humming noise be related to needing the rear brake pads replaced? So sad..only just hit 19,000 miles. I was wondering if folks have had issues with wheel bearings and maybe that was also the cause of my noise. I have taken off my tire and checked it out and there is nothing stuck in it at all that would cause noise:dunno: Thanks for any help!
