Just recently I decided to swap my Dana 60 stub shafts for the 1.5" 35 spline shafts and upon removing the inner shafts, discovered they are the less desirable tapered shafts. I got a decent deal on some non-tapered inner shafts, so I'm gonna go ahead and install them. One question though, do I need to replace anything like seals or bearings to make the straight shafts fit? The axle is pretty freshly rebuilt so seals and bearings should still be good. Thanks.
