The rear axle shafts on my Ranger are all chewed up where the axle bearings ride. I have a 1991, 4.0L, 28-spline, 8.8" open rear end with 3.55s. I wanted to know if the axle shafts are the same if I get them out of a 28-spline 7.5" rear end. From what I found in the tech library, it seemed to me that any 1983-92, 28-spline axles would work regardless of ring gear size. Please correct me if I'm wrong. Thanks alot.
