i took mine out yesterday to punch out broken shaft i didnt use a spreader just light preasure with a pry bar ,on refitting i used the journal bolts to pull it back in. i fitted a detroit locker a year ago using the same method to shim the backlash i think the old engineers [im 60] tend to complicate things go for it. the only problem is to alter the backn lash you have the pull the bearings off which is another story and learning curve.
