I guess I used the term axel wrap too generally. When your vehicle 'stands up' with the parking brake applied, the same forces are at work, just not to the same extent.

"Wrap-up - Referred to as both rear spring and rear axle wrap-up. As power is applied, torque load causes the rear pinion to pivot upward. Once this load reaches a certain point the leaf springs begin to deform, which stresses numerous driveline components. The "fix" is to increase spring strength, via add-a-leafs, or install traction bars."

I know that this definition is for leaf springs but similar effects will be in play with coil springs. Remember when Kicker shocks, sub frames & ladder bars were the 'all the rage' with agressively lifted trucks? Those were all cures for axel wrap (wheel hop) just like steering stabalizers were supposed to stop 'bump steer'.
