In my auto shop class, I was doing some brake work on a newer Jeep Cheroke Laredo, it was on a lift. The rear end looked pretty narrow so I took a look at it, I couldn't find a tape measure but I know it was like 53", I'll measure it if it is still there monday. It is a Dana rear end, I think it is like a Dana 30 or 44, not shure, factory disc brakes. not shure about gears. Probably lots of them in the yards.
