The axle in the "full size" Jeep is not the same as a full width truck axle. The axle you have is more compared to a stock YJ axle width. We use them a lot in YJ's to keep the axle width very close to the same. Makes for an easy swap. A good axle to use for the rear is a Rodeo axle. It is the same width, same lug pattern, is a Dana 44, has 4:10 gears, and has disk brakes. If that helps.Richard w said:That is what I thought at first but what got me was the 60.5" width, I thought the full size were aroung 65" ??
