Same. That's kind of crazy. There was a wobble front to back and up and down that manifested itself on the pulley - the root of it was the shaft behind the pulley that runs to the back gear case. It was minor and barely visible, but add lots of rpms to it and it spells trouble. Eventually it would have also cause bearing failure. I did take some videos of it all for whipple to review. If you touched your finger nail to the smooth face of the pulley at idle, you could feel your finger fluttering from the wobble. When you do that now, post repair, it's smooth and true. They rebuilt it, new shaft, new bearings.I had to send my whipple in for warranty work as well. Are you talking about the pulley? I'm not completely technically versed.
My whipple had to have it's pulley replaced, and they rebuilt it as well - "just in case."
Our units only being built likely a month apart must have suffered from a batch of bad shafts or something.
