Back from the dead; just had the PS wiper on our 05 do this. The spline had only come out about 1 inch though so no damage to the paint. I replaced the blades on both cars (06 also) to be safe as they were both the same design.

 

...and the thread arises from the dead yet again...



Glad you caught it before it did any damage!
