Banging noise under van

[ChrisG]

Hi folks,
Can anyone help? Not technical minded but learning fast...

Occassionally when I go over bumbs or turn round tight bends, I hear a single bang or clank under the van.
It seems to be coming under the drivers seat or at least on the drivers side.

I have looked underneath and cannot find anything loose.

On straight roads it is fine, running smoothly. Even if I go over a speed bump slowly, no noise.

Any ideas?

Thanks
Chris

Check shock absorber mountings closely or even anti roll bar and its mountings.

Sounds silly, but also check for cans rolling around in cupboards or the fridge. Sounds like a thump from under the van when they hit the sides.............

upper especially or lower ball joint worn ?
check boots for integrity , often split no grease you can sure that's worn, if not obvious then you need the vehicle in the air and big pry bar to test for play it's a mot check obviously so if not recent mot then could be fault, also broken antiroll link rod swinging around loose can be problem sometimes
