Steering wheel and gas pedal high frequency vibration when accelerating at 1500 rpm to 1800rpm (in various speed). I had taken this concern to my local Toyota dealer. The dealer service was good, but no solution provided. The reason was "all 4 runner v8 4x4 do this, and there is no TSB solution for it". I have seen complains about this annoying vibration in '03 and '04 4runners in various place - edmunds. Com, this site, and etc. Should Toyota consider this a defect of the vehicle and provide a solution?.
Steering wheel and pedals vibrate in 1600-2000 rpm range at various speeds.
