I've got a 2002 Sequoia Limited, and bought the truck with 50K miles. It has 65K now. At 70 mph, there is a harmonic kind of vibration wa wa wa wa sound. Above and below 70 no noise at all. Not sure what to try to look for, but it is annoying an you can feel a little vibration that seems maybe wheel bearing related? I've jacked the truck up and spun wheels and they seem fine. Truck has brand new tires and brakes, and shocks and struts are fine. I need help. Probably going to do a tranny pan drop over the weekend, but I don't think it is tranny related. Any advice would be helpful. It does have ABS and the trac brake system, which I know little to nothing about.
