Moin! With my 9-5 EZ 4/2002 the driver’s seat is shaking slightly. He probably has, as it feels, some play in the seat rail. When braking and in left turns he makes a sound (“knock, knock” by the load shift. Is this a discreet indication that I have reached my slaughter weight?? Does someone know this tipping problem and know what to do? Or should I rather go to my screwdriver? Thank you! Greeting: Stefan
