So, I have a 2006 TJ and it has a Rockhard 4x4 rear bumper and tire carrier. Well whoever installed it didn't put any grease in the bearings on the swing away tire carrier. I called Rockhard 4X4 to order new bearings and they sent me all the bearings and oil seals free!.. Talk about standing behind your product. Hats off to Rockhard, thier products are great and they are awesome!
