Sooo.. .. false alarm.
The small bearing under the seal had wrong shape even though all dimensions where the same , and it came loose. My fault didnt see that the guy sent me wrong part number. Bought the correct one and everything ok.
Still dont undestand why nissan say to torque it 19 to 30kg.
I tighten it until it felt turning good without binding and after driving for 1-2 hours no problem at all , no strange sounds or anything. We'll see hot it goes !
