Im no mechanic but it could be a wheel bearing on the way out! Perhaps a drop link in the suspension (My mechanic told me about this when I snapped mine creating an almighty racket). Other than that just check for loose bits. The plastic covering the bottom of the engine (like sump guards but plastic and S**t) snap and come loose sometimes. Im sure theres a more knowledgable member on here who could spread more light than this though
