        1 2009 Wrangler - zvdb

        This doesn't fit.

        Doesn't fit my 2009. In fact, on the 2009 it's a one piece design. This one got mis labeled somewhere along the line. This does not fit 2007-2011!!!

        5 2005 Wrangler - CowtownSoldier

        05TJ Leaking Ship

        This TJ has been leaking oil since I got her so I bought this seal after watching a youtuber fix one. This seal looked different from what I saw on the on the vid, but it was the right fit after all. Worked good, and don't forget to get some RTV if you don't already have some in your toolbox. Seal was for the 2005 TJ Wrangler 4.0, and it does fit, and will stop the drops of oil on your drive way!

      What is the diffeence between this seal and the crankshaft retainer/seal kit item#J113189? In other words do they both need to be replaced? I already purchased the retainer/seal kit, do I need this one too?

      • The Crankshaft Retainer and Seal Kit will include the seal as well as the retainer, so you will not need to order an additional seal.

      Will this fit a 2011 JKU rubicon? Or do I need a 1 piece rear main seal? Both types say they fit....

      • The Omix-ADA Rear Main Crankshaft Seal will fit your 2011 JKU Rubicon.
