[Vwdiesel] Bad vibrations ...

[Derek]

Although I realize that diagnosing a vibration over the internet is next to impossible, I appeal to your wisdom as I am at my wits end.   While driving if I make a slight right turn ( as in a curve )  I get a vibration that I can feel in the floorboards and is really audible. It would appear to be coming from the drivers side front area.  It is quite noticeable when the car is cold, but reduces somewhat when I have driven it for about ten minutes or so.  I thought that it might be my CV, but nope.  Noise was there before and is still there after a recent replacement.  I figured maybe its my tires, but nope again.  I just put my summer rims on and no dice.  Damned thing is still there.  I did notice something when I changed tires though.  I had a hard time lining up the bolt holes on the drives side.  I thought that a bit odd and don't remember that happening.  It would appear as though the locating screw is broken or missing. ( I came to that realization after I did the other side of the car and had already put the drivers side tires on, duh ... )  Could that darned little screw be causing this ?  I wonder if when the rim is tightened down does it put all the pressure on the rotor or on that little bit of the hub that pokes through the rotor ?  Either way I will repair or replace that screw tomorrow, but I wonder ...
