Hello:
Well, my issue turned out to be tire noise, thankfully. On a side note, I have since found out, from a slip left in the vehicle, that the hub/bearings have already been replaced in March of this year. The slip listed them at 250.00 each. The brakes were also done on all 4 wheels at the same time, including new rotors and pads. The total bill was 1200.00. Thanks again for all the input.
