I E-mailed John Deere to see if there sockets are guaranteed for life and I was told only if you have a receipt. My receipt is long gone and so is my warranty. Too bad an American company with American made tools is just too cheap to replace my split socket. My Cornwell tool rep always takes care of any problems that I have had in the past. Anyone else have issues with tool companies and there warranty policies? Thanks for reading, Mr. Pooman
