I was wondering if anyone knows of a complete list of yearly changes too the JK? I have found out quit a few things over the years that were just small things but would like too have a list to refer too. A couple examples. In 2007 the JK's didn't have the holes too put on the hook below the rear bumper, I believe it was added for 2008. I have heard that the front axle was strengthened for the 2013 D44. Have not confirmed though.
