Pull the plug and look in through the fill hole? The only mechanical thing that can screw You, and I've only seen Moser's shortened C-body axles in an A-body housing do this,
but if the splined end of an axle twists or shears in the sure-grip to side gear interface, You ain't never gettin' them out. That'd mean cutting access holes in the housing and
burning the axles in half just outside the carrier bearings.
