hi my name is Adam, I have a 2006 nissan frontier extended cab. I have been noticing an annoying vibration type sound at slightley around 1500 rpm and then extreme vibration at 3500rpm. i think it could be something with the fan im not sure. i checked for any lose objects in the engine compartment and i found no signs or any problems.i'm also new to DIY maintenance and i enjoy it alot!! thanks for any help!! - Adam
