Hi there, I had the spheres replaced a few weeks ago because the car used to be an extremely hard ride, the old ones were shot, and with the new ones on the car is much better. However, the car seems to clunk over potholes at the front and back of the car (not that I purpously drive over them) but compared even to my brothers vauxhall omega I would have though a Merc would be better over bumps. The car has rear self levelling, but this is working fine, it is also very smooth over speed bumps, I wonder if anyone is having a similar problem to this. Or any ideas on what I should get checked out?
