Harmonic Vibration

Greetings,
2010 Tacoma 4x4 TRD Sport.

I am getting a harmonic vibration that I can feel through my steering wheel. It is really pronounced at 62mph it is a low frequency harmonic vibration. When I turn my wheel quickly to the left it subsides but when I straighten the truck it comes back. I have had the tires rotated today. I shifted to neutral at 65 and let my foot off the accelerator to coast, but the vibration is still there.

Any ideas of what this could be? Axel, wheel bearing, suspension?

Any input would be greatly appreciated.

I would certainly check the front left wheel bearing. When you turn to the left, you unload the left side and that will quiet the left wheel bearing down. Jack it up, use jack stands, grab the wheel at 12 and 6 o'clock and rock it to check for play. Also spin it and listen for noise. There could be other causes, but since it quits when you turn left, check that left wheel bearing first.

Does it make noise at lower speeds?

 

I would also suspect a wheel bearing...
