when you jacked it up did you check your bearings for movement, jack it up again and grab hold of the wheel at the 6 and 12 o clock position and give it a wiggle if there is any movement then your bearings are on there way out, and is it deffo a rattle and not more like a slight knock, and when does it make this noise, is it when it's going over bumps or just at certain speed's, it could be a few thing's lower arm's, ball joint's or drive shaft or your suspension top mount, but i wouldn't think it's the latter because they usually only go on older car's but you never no,
your best bet is if your not that mechanically minded i'd take it to a good garage that someone has refered you too and have them check it because sometime stuff like that can make you pull you hair out, and cost you more replacing parts you didn't have to
