so here's a pic of where I park, it's a Jeep 4.0 with 60,180 miles on it. I'm guessing no one needs more than that to know I have a rear main seal leak. It showed up right after I switched to synthetic oil, and it's on my winter fix list. Does anyone know of an upgrade to the rear main? Any tips or anything before I dig in? I've done this seal before on my old 88 YJ's 258, it wasn't too hard except that I screwed up 2 of the top sides before getting one in correctly, so I ended up buying 3 seals overall. Any tips for getting the top 1/2 in easily? Thanks!!
