the strange noise is made when accelerating above a particular speed
i'am worry about my 06 ctt .. please help me
at 00:45s the strange noise sounds... i can't find the cause of this sound.... it sounds when accelerating only above a particular speed. . if the gas pedal is taken off , this sound is not made.. .. you clearly hear the noise at 01:03.
this link let you hear what the noise sounds.. how can i fix it? is it problem of my transfer gear box that has something problem "4 wheel drive system faulty" shown irregularly ?
i'm sorry that i am not gut at english....
and thank you

Sounds to me like either a bearing or tire humm. How long have you owned the car? Is the noise new and wasn't there previously? Have you changed tires recently or added wheel spacers or done anything like that?

When the noise starts put it in neutral and coast. If the noise changes it's probably not a wheel bearing and may be a loose heat shield. If it sticks around in neutral then weave back and forth a bit in a safe place while coasting and see if/how the noise changes.

heat shield problem?
SHIFT 'D' + stepping on the gas pedal => noise
SHIFT 'D' + Not Stepping on the gas pedal => No noise
SHIFT 'D' + Stepping on the gas pedal at low speed (~ 10KM/h) => No noise
SHIFT 'N' + stepping on the gas pedal => no noise
SHIFT 'N' + Not Stepping on the gas pedal => no noise
when the shaft and the transfer case is loaded, the noise is made....
Many helper said that heat shield problem... how can i check it?
and In my opinion, i am suspecting of transfer case or bearing... but the center bearing looks fine... umm in transfer case.. the one-way-bearing is in ? i think that if one-way bearing in transfer case or diff... , the shaft is not rotating and not loaded by any force when the gas pedal is not stepped on in "D"

Can someone sit in the back and say what side or middle?

Most likely the transfer case or a differential if swerving does not seem to affect the noise much. Also check your driveshaft support bearing. Mount a camera underneath the car near each of these parts and see which one makes the loudest noise on record. You could also try a temp gun after running it at highway speeds and see if you can find anything abnormally hot.
