Hey, I have a 06 Taco, auto, and I have this strange whirring noise that I hear at aournd 30mph...and the faster I go the faster the whirring noise goes...and the same when I start to slow down. There is a small vibration in the floor as well. I changed the tires as I was told the old ones were cupped and aggressive and that could be my problem but now the noise is lounder with brand new tires (not aggressive at all). I've checked all fluids and I even had the shop check the wheel bearings and he said all was good. (although he just checked for play in the bearings).
Its driving me nuts, I am going to have to go to the dealer soon...Any help would be appreciated.... Thanks
