On RWD cars with clockwise rotation engines, regardless limited slip or open diff, the R (passenger side) rear wheel will lose traction first due to more weight being put on the L(driver's side) rear wheel.
The driveshaft pushes against the pinion gear, ring gear, and pushes the L rear wheel against the ground. If you think in terms of what's happening on the engine cradle, the torque is pushing the cradle counter-clockwise. Then, looking down the frame rails, would it not twist the frame clockwise? It's not getting twisted from the rear, it's getting twisted from the front.
The engine cradle has nothing to get twisted out of shape, so the extension of the frame rails towards the rear get leveraged out of shape and hence the raising of the passenger side frame rail in the back.
The engine cradle may suffer from some spring compression that would account for front driver's side sag.
OK I'm throwing this out there! LOL
