Giacias to all for their contributions. Unfortunately the problem persists. I give you a hypothetical situation. If I pass through a bump with the right , I don't hear anything. But if I pass the same bump with the left , then the blow is heard. The blow is as if the shock absorber was bursting (as it is no longer useful). I do not know if the spiral (or spring) that I put is thinner than it should, or if its resistance is already defeated, or if the Macpherson itself is already damaged (although as I said there are no liquid leaks). I would not even say that a MacPherson is thicker than the other because I changed both at the same time. Send me how much they know, I am attentive to your contributions. Once again thanks.
