Posi Question

Cones don't have the notch and tang, I suppose it could be spider and side gear backlash. I sold my last cone type unit a few months, I wish I still had it so I could check it out. Being the side gears ride on the cone and when the cone & carrier starts to wear it will move farther away from the spider gears which would create more clearance between the side and spider gear, it must be this, it's all I can think of without looking at one directly.
