Cracks at the front Left while turning in and bottom shaft….

Hi, I know that there are threads that have to do with poltern and similar on the front axle but unfortunately this is not really my problem. My Antara 8/2009 with 19TKM sometimes has a slight crack when driving at the front left, but only when it steers to the right, so the left front wheel gets the spring load when springing and I drive a bottom shaft or similar slowly. Now the coupling rod and the stabi was examined with the FOH but nothing at defects found. My FOH meant just keep driving and if it gets worse then again. Somehow I can’t really accept it because he does the ONLY front left, on the right you don’t hear anything, although not every time it gets annoying right! Now it was -8° this morning with us and there he made it stronger, so in cold it’s probably more common to hear, but can also be that you can’t provoke it, then again he does it again, it’s definitely ONLY when I “la ngsam” to the right and there is a floor wave then he makes it funny, but sometimes he doesn’t. Now my theory tells me that either a rubber or the cathedral camp or whatever at the damper might cause that. Do you have an idea what I could try myself? Since he doesn’t have the problem on the right, but all the coupling bars and rods are purely externally in order and firmly it is close that it is a rubber or something in the direction. Who has an idea?
