I have an 01 caravan and when I hit a speed bump or even a bump in the road I hear a knock in the front end that I can feel through the steering wheel. When I put the front end in the air the only thing that feels a little loose is the drivers side cv joint. It's not badly loose but when I grab it I can move it up and down a small fraction. Is this enough movement for me to feel this clunk in the steering wheel?

Thanks
