I bought a 2008 wrangler two door. With a automatic trans. 3.8 v-6. I bought with only 4000 miles from the stealer about a year ago. My question is i think the last owner might of changed the rear gearing. But i dont know how to find out what it has. I replaced rear end with a fresh gasket due to a small drip. So i know the rear end cap was taken off at one point. I did find some numbers on the main gear. It says 7N Dana D 2008689 p8L015 41 11. The axle says AA373. Does this make any sense.
