So just bought 11 jk 108kml in September, and have been going through doing maintenance and researching everything. So we are planning on going to a offraod park this spring, and noticed something worry some. There doesn't seem to have every been an accident via Carfax, but the rear end and trans fluid was black, so I changed it. Then I noticed some chaulk writing on the rear axle. The back yard build side of me makes me think salvage yard axle. Which if it works and still is a Dana 44 then ok, but started thinking further. About gearing, I pulled the build sheet for my jk and it had 3.73 optional gearing, now I'm wandering if in is a different rear end, then if it is did they match off build sheet or just grab anything. Because what ive read says 3.21or 4.10 stock, so landing another 3.73 at a yard, not probable. Of course all of this is speculation, but I don't want to go in 4x4 and have 2 differ diffs, and burn up transfer case. But I also don't want to spend 600+ dollars on a guess. Is there any way to know?
