Have someone shake the car (push hard to get it to rock from side to side) while you go around it and work out where it's coming from. If nothing else it will be a good workout for them.
Easier to work out where a noise is coming from when it''s stationary and there are no road or engine noises to get in the way.
Noises could be door locks and stops not tight, Rubber bonnet stops not out far enough so bonnet is knocking on the latch, suspension bolts not tight, wheel nuts not tight, ARB chassis mounts as well as drop links, Damper mount bolts/nuts not tight etc etc
