We have a customer with a Citroen Berlingo Multispace, the latest shape. It has a suspension rattle on rougher roads. We've checked everything, springs, antiroll bar bushes, drop links, spare wheel carrier, track rods, rack. It has only done about 20,000 miles so there shouldn't be much wear anywhere.

We are getting to the stage where we are going to have to start replacing things in order to rule them out. Do these have any common problems with suspension knocks that we are missing?
