Rattle only when backing up hard. What is it? Anybody had this?

[shiro1745]

I just realized this morning when I parked the car. Backed it up a bit harder and a heard a rattle coming from the engine bay area, possible under the front of the car. I tried a few times and it does it every time. It gets pretty loud if I accelerate hard.
It's a MT FWD if that could make a difference.
Thanks guys!

UPDATE: I forgot to mention that I just got my car back from audi. They changed the cam follower, the two cams, HPFP. Could have anything to do with that?

It could be a clicking. But it's more like a deep clicking, if that makes any sense.

i'm going to guess cv boot. Wheel turned?

I thought I heard it a bit louder when I had the wheels turned a bit. But I could try turning them all the way. U think this could tell if it's the cv boot? And why would it do it only when backing up? I'm sorry for all the stupid questions but I'm not too experienced, I'm just trying to find out more.

Gross! He likes to back up hard. No, really, who does that? I haven't done that since I had my first car, the Toyota Tercel Hatch from 1987. Front wheel drive donuts backwards bitches! That was the last time I backed up hard. I was 15 too. I can't even see out my windows well enough to back up faster than a quick roll in neutral.

I figured nobody ever back up hard, so by actually saying this so straight I thought it would be a good joke.

... me wrong here ...

I felt this rattle while backing up and getting closer to the curve. So it was nothing but normal driving. And I know what you're saying, there a lot of cases when I have to put my windows down to see something in the mirrors when backing up.
