Hi, new member from New Zealand, I have a vibration problem in my 2008, D40, 2wd, auto, 58k,at between 95kph and 105kph, appears to be comming from the rear, I have had the wheels balanced and changed front to back, but still there,the nissan agent has had a look but can't or don't want to find the problem, have already replace front disc's due to cracks, any help would be greatly appreciated.
