Hi, As the title already says, I’m not sure at the diagnosis. The following problem: After last year, I could turn off a pinion of the pendulum’s, now have a metallic cracking. After the listening test during the ride, I could locate front right,. By forcefully pulling down, at the Stabi, I mean, it comes up from the wheelhouse. The usual joints, transverse handlebars, track rods, LZH, I can actually close out. My thought went peculiarly ch first again to the pendulum. But this time I unfortunately could not make it out as a source of error. Also a mirror, to examine the spring coils, in the damping disk did not really bring me further. Now to my question, …. What could cause a metallic cracking on the spring leg or the spring itself. And can one determine a broken spring during shock absorber test, if that should be the cause for cracking. I do not know if it is important or just Random, but it only occurred after this year’s winter tire change.
