After attempting to replace a wheel bearing, I have accepted failure, and am frankly having a fun time putting everything back together. But To remove the axle, I had to unscrew the retaining pin from the diff, and then remove the big pin/block from the center of the diff. Thing is, I don't remember which way it goes back in!!! Either way, the diff still operates, I think it's just for lubrication but I wanna get it right. Can anyone describe how it goes into the diff? If you need a pic to refresh your memory I have one. Thanks a lot!!!
