Making The Weak 7-1/4 Rear Axle Live... Kinda
Firing up this thread again.
We know a sure grip unit for 7.25 rear is harder to find than old pirate treasure. So doing an lsd conversion may be the way to go if we can figure it out for a reasonable cost. I kind of have a plan, it will require some feedback though.
We know when a bevel gear is driving another bevel gear that they want to push away from each other and the greater the force against the gear the more force there is pushing away. So rather than having the shim on each side on the gears splined to the axles, we use friction/clutch disks instead? I know other lsd diffs use 4 or more clutches and having two is a compromise but maybe this with a mechanism that provides preload on the two gears and can apply extra force when the pin kind of rotates in the mechanism's slot we get not a true lock, but still a limited slip differential.
Now of course this means the splined bevel gears are now wear parts because it's rubbing against the friction disks, but most of the time when I service a higher mileage differential, I end up changing the spider gears anyway.
Any thoughts or ideas, let me know.
