[away3d] Max3d import issue

[SasMaster]

I have a problem as follows: I imported an object from 3ds max :its a
car with 4 wheels ,each part is separate one from another . each
wheel's pivot point is exactly centered  locally but after the import
when i give the rotation to one the wheels it appears that their pivot
point is offset. Anybody has a solution for it?

code:  "fr" is the name of the wheel that was given inside 3ds max
private function handle3dMax(e:Event):void{

                          df.getChildByName("fr").rotationZ+=10;
                }
