Making The Weak 7-1/4 Rear Axle Live... Kinda

Ok, I see it now. But, as you said, the gears now become the "clutches" so to speak. Very high wear. Also, unless you somehow convert the unit to four spider gears, good luck with any type of performance driving.
Hmmm... then maybe that other device thing from post 27 help a bit. That puts most of the load on the side gears and the pin.
