i don't know if its the same problem as yours, but with my 99 golf, when i bought it, every time i used to drive over pot holes an rough roads, i used to here a clonking noise, first it started coming from the front left side, then a few days later the front right side.
so after going to my local mechanic, first he said it might be the suspensions, but he had a look and said nah the suspensions fine, then he said it might be the anti row bar link, so i had them both replaced, an to this day that noise has gone.
don't know if this helps mate, but it sounds like the same fault as mine......
