I see what you are saying Ron. But you are making a fundamental error. The reactive torque is not absorbed by the TA, but by the engine/transmission unit. This is why the nose of the trans wants to rise on acceleration. There is no rotational torque applied to the TAs. They just support the bearings.

The phenomenon you describe occurs in solid axle rear ends like 60s and 70s American cars have. When they install ladder bars (which look like the spring plate substitute on that red chassis car 2 pages back), the ladder bars are fixed to the axle housing, which is fixed to the diff housing. When they launch, the front of the rear end wants to rotate up. By installing ladder bars, the counter rotational force causes the whole rear end to be forced down, creating more traction. In a VW swing axle, some guys do install links that look exactly like the ladder bars on an American car's rear end. But they don't have any function except as a trailing arm. This is because the VW's axle tube is not rigidly connected to the rear end housing (trans case).
