Defective drive shafts on new Forester

Hello Subaru Fansgemeinde, the drive shafts on my 2007 Forester make strong imbalance noises. Lt. Subaru dealer works the manufacturer on a solution. Until then one should be patient. Can this not affect other components?. By the fact that the noises with increasing kilometers (currently 2300) become ever louder, the statement of my dealer calms me little. Which way would you go in my place?
