Taken from one of the links you provided:

The condition you feel is called "crow hopping" and is common on 4WD trucks making tight turns on dry pavement.


It's interesting that Bob Weber (from thecarconnection.com) doesn't seem to agree with the term used in that context.

Here are a few examples of "crabbing" used to define the same thing:


Crabbing is basically driveline "wind up" from each wheel/tire wanting to turn a different speed when going around corners, the front wheel joints make it even more pronounced with the speed-up / slow-down associated with a conventional u-joint. At some point you must have some tire slip to relieve the wind-up.

It almost sounds like you are getting a CRABBING effect. This is also known as Axle Windup. Which is normal on 4WD with a “TRACTION LOCK” rear differential.

There are a truckload of other examples, but I'm sure you get the point-- there are many different terms used interchangeably for the same effect.
