Peugeot 307 Sport 2007 - Rear Suspension 'bottoming'? - albanian

I recently noticed an increase in a bottoming type noise in the rear suspension when hitting otherwise normal depressions/bumps in the road. The road clearance at the rear looks normal. It is worse with a heavier load or passengers. The car has about 29000mls. Any ideas?
