Hey Beamin, you might be onto something there. A cross-link valve stuck open would do it, allowing air to swap sides at the front or rear when cornering. They're opened at slow speeds on uneven surfaces even in high range. The bad effect would be identical turning left or right. I would expect a driver could tell if the front or the rear was at fault from which end leaned more.

I can't think of a way to prove the idea using diagnostics so perhaps have to get the dealer to try replacing 1 at a time, or just both at once.

It wouldn't cause increased front lift under acceleration though.
