Hello, from the beginning of the purchase I struggle with the problem of hard knocks hanging. when I go on a smooth road, there is nothing knocking, the noise begins after driving on the cobblestones, transverse unevenness of the road, on a dirt road the same thing, breaks as if something was to fall apart. in the meantime I replaced front shock absorbers, stabilizer links, stabilizer rubbers, shock absorber bearing pads, new discs and pads. please advice.
