Good morning! I'm new in this forum and I have a major problem with the front differential with my Jeep Wrangler Sport 2006, 6 speeds manual transmission, 2 door, 4.0 liter, 6 cyl. in line. The sticker on top of the differential case is almost gone and very hard to read whatever is left. I understand there are several types and I would like to know which one I need to get to fix it. Can anyone help me out?
