So I jumped the gun without thinking things through completly. I began trying to remove my diff. Bearings to replace them and adjust backlash. But I forgot to measure the back lash. I already destroyed one of the bearings, should I just estimate how many shims to move based off of the backlash I noticed befor I took it apart? Also im having trouble removing the bearing do I need to split it off? Its a Dana 44 tapered shafts with a Powr-Lok on a 65 Scout 80.
