I have just bought the wife a Merc A140 Elegance 2000 W plate on 46000 miles. We have had the car for a month and when bought was immaculate, unfortunately just recently there is a loud knocking coming from the rear passenger side underneath the car when going over speed bumps or taking a corner, usually when the weight distribution is left to right. Any ideas what it may be and possible cost to repair?
