light weight is 100% key.. Having done Mini Baja for a bunch of years, anything other than a locked diff is going to be extra weight and most likely break.

If you have the right LSD.

OK.. So I need to stop posting but here is an idea that might work. If I had a CAD program on this laptop I would draw it for you but essentially it is a one wheel drive setup. So lets do some ascii work.

X ------------ T ----- C ------- X

So effectively X is a wheel. T is the drive sprocket. C is a shiftable collar.

How I envision it working is that T will be locked to the X on the left(bolted) The line would equal a drive shaft. The collar could be bolted to the right side of the drive sprocket. If the need arose for you to have a locked rear end your driver would pull a lever to slide the collar over to link between the two wheels. It would be very similar to a front axle disconnect system in a Jeep Wrangler YJ.

If you made the driveshafts out of square tubing you could have a larger section of squre tubing that would fit snugly on the inner "driveshaft" and slide over to make the connection and transmit the needed torque.

The drive could then pull the collar back to facilitate tighter turns. The shifting mechanism, the drivers arm muscles, and the collar itself would have to be fairly robust.

Do you understand?

This is a system from a dodge ram front end... kinda similar.. make it simpler and you might get it to work.
