I need some insight into what I may have done, need to fix.

Last week I was caught out on some ice, and slid at about 5km/h into a curb
sideways.  There was absolutely no detectable damage to the alignment or
drive train - The car runs perfectly at 160km, straight as an arrow and
quiet as a church mouse.

The noise has no beat to it.  It is a solid tone hum (Not very loud - But
being sensitive to every sound of my car, I notice it). One suggestion that
was made was that I may have bent the steel belt of the tire - But I
discount this because of the fact that the car tracks and the noise
disappears when at 130km.

What I have noticed is that there is a small dent on bodywork (About 2 cm
indent) visible when viewed from ground level looking up. The dent is in
about the middle of the front door frame along the bottom.  There is no
change in the door alignment or spacing between the frame and door.

Also - Speaking about the front driver wheel well.  The plastic lining was
ripped at the front of the tire well about 3/4 of the width across from the
outside to in, about 5 cm up from the bottom of the front side mud guard.

Any thoughts at all would be appreciated.  I plan to have the car looked at
on Monday. I want to have a plan when I speak to the dealer.

I am willing and happy to email photos if that would help.

Thanks
