There's a knocking noise coming from underneath my car - do you know what it could be?

My Peugeot Partner Tepee recently developed a knocking noise from underneath the vehicle when I go over bumps, rough road etc. I've had it looked at by two different garages and they can't figure out where it's coming from. Has any one else had this problem? I'd be grateful for any help.

Probably the suspension banging against the exhaust system on compression. Just needs re-adjusting. If it's a harder knock then could be that one or more of the anti-roll bare sleeve bushes have dropped out.
