Has the wheel alignment ever been adjusted ?
If the wheel alignment has been adjusted and the person doing it was lazy and only adjusted one side instead of adjusting both sides equally (very common, sadly) it can cause an offset in the steering rack that lets the car steer too sharp in one direction.
This can cause the driveshaft to rub on the CV joint housing only in one direction which usually sounds like a scraping or rumbling noise which goes away again if you turn the wheel ever so slightly back towards straight.
Normally this would cause the steering wheel to be offset when driving straight ahead but that is then sometimes covered up by removing and refitting the steering wheel instead of fixing the original problem !
You can still tell though by turning the steering wheel from lock to lock and making sure that the wheel turns exactly the same amount to the left as it does to the right. If it doesn't, an offset rack adjustment could be the problem.

Behind the brake disc is a guard. It's about the size of the brake disc and the disc sits slightly in go it. Get under the car and see if this has any damage to it. Mine made this noise once and i found the guard had taken a knock, probably from a rock kicking up, which had dented it slightly making it rub against the brake disc when turning.
Assim à primeira vista não vi qualquer raspadela ou marcas visíveis de dano nas rodas ou no compartimento delas. Mas depois de ver tantas respostas vossas sobre esta situação, parece-me que há qualquer coisa na direcção dos Leafs que não é assim tão raro e que vale a pena comunicar à Nissan numa próxima revisão. A minha é mais ou menos daqui a um mês. Depois ponho aqui o resultado da revisão e deste apontamento.The typical cause of grinding noises when turning the steering wheel is low power steering fluid. The power steering fluid reservoir should be checked and the fluid topped off if it is low. Air trapped in the system from leaks or recent repair work will also cause a grinding noise. A loose or worn power steering belt may also cause the noise.
