can u pinpoint if its from the front left, right, both. with a mates help u should be able to tell if its from the top of the strut or not. mine is creaking from the top on the left only. from what my mechanic says its a case of either genuine nissan or him manufacturing his own. which he has already done but its really co$tly. mine has been creaking on and off for a month. sometimes i can go all the way to brizzy and back to the sunny coast without it making a noise and other times it will creak the whole damn time. i recommend getting it checked out by atleast 3 or 4 mechanics. get one of the $14 pedders suspension safety checks. they might pick it up. in my case they didnt but they picked up a few other problems and for $14 its worth it. good luck
