strange sounds can sometimes be narrowed down to a smaller area by the nature of the sound, different types of sounds can be generated from different situations.
Rumbles and squeels are normally found where the parts that are effected are rotational such as bearings , brake disks/pads etc , clunks and clonks are more likey to be static type issues where the parts themselves are fixed but are loose or have become worn and are no longer a secure fit such as bushing etc, or fixed parts that have become loose and are moving around , sometimes a combination of both can be to blame.
Possibly drive shaft issue or CV joint or joints aswell as they are rotational but will clonk when worn.
I'd be getting the front end jacked up and check all the bushes first for excessive play then work from there if its a clonking sound, just a though chap.
