RE: '99 Camry making humming noise
oh yea sorry forgot to tellyou but we already tried that. We switched my tires with those from another camry, and itmade the same exact noise. And the mechanics seem to be stumped as well. One tells me its the transmission, another says its the bearings, although, its definately not the transmission, andi've changed the bearings in the front, and this is where the sound seems to be coming from.
