Thanks NSEU. Any explanation for the reason why you hear and feel a creaking or vibrating noise when the tiller has been moved to a significant angle while taxiing. As soon as you back off the tiller, it seems to go away. You can hear it in the flight deck and the lower deck. Sometimes as a passenger I have heard a cable movement kind of noise as well on the lower deck.
The other day we were lined up on the runway for a while and there was a similar noise. One guy said that it was possibly the body gear trying to straighten out. We were at max weight.
