l know, this is a odd question.....but l've had my 02 ML 55 for about 1 week and half now, and its a "real blast"...l have a few items on order, that are under warranty, and soon she will be in for some TLC...but lately, when l reverse out of my driveway, and go over the bump..l heard a "Clunking sound"..its hard to describe....it can be fairly faint at times, but l don't hear it going over bumps on the roads, only on more severe drops like driveways....any idea's guys......maybe's lower arms?????l have 66,000 KM's, on her, and l certainly want to cover this under warranty....
