Torrifying sounds on the rear axle

Hi, everybody! For some time now I have noticed creaking/smoking sounds from the direction of the chassis at the rear right. Only occurs at step speed/ranking on uneven ground. Have my Ommi also swinged by hand, but there is nothing to hear. Last week the rear dampers + impact buffers were changed (because leaking), but the noises remained. KM-Stand aktuell: 108000. Who can give me a hint?
