I am looking for some info on the Krank Formula 5 driver. I have a ferrule that is sliding up the shaft and am looking for my options before I remove the shaft.
If the problem is just a loose ferrule I would slide it up the shaft and then take a thin piece of sand paper and lightly sand the shaft just above the hosel. Mix up some epoxy and cover the sanded area then slide the ferrule back down into place and clean up the excess. The epoxy will secure the ferrule and keep it from sliding up the shaft. Here is the link for Krank Golf if you need to contact them. https://krankgolf.com/
