Often the sources of knocking at the front of the vehicle are not the suspension but the steering gear itself. The design of this site on Logan makes it possible to make a sufficiently strong knock at different rates at different speeds.
The safety of the car is not affected. The roll of the rake is even with the new Logan. Cars issued before 2009 can be "cured" by pulling and lubricating the shaft (viscosity of the NGLI1 lubrication). The late cars are no longer available-only the replacement of the rake can be helped, and it won't be for long.
