7.25 carrier won't come out

The hex is 1 3/8 inches. You can use a old torsion bar (I think "B" or "E" body). An "A" body torsion bar will not work, the hex is too small. I made a tool from an "A" body torsion bar, by welding a nut with the 1 3/8 hex, on to the end of the bar. Then insert the bar in the axle tube, put a wrench on the hex on the end of the bar that sticks out, and turn.
