Mexstan, when it will cause increased tire wear as you stated. You are also correct on the varying speeds on the axles when turning. When you turn with 4WD engaged on wet or dry pavement, or hard pack dirt, the only way to release the strain on the drivetrain of the different axles is for a tire or two to slip. You will feel a shudder when that happens. If all four tires have good traction and a tire can't slip to realease the tension, then something will break and realease the tension.

Here a quote from another site on the subject :

basically when you go into a turn your front wheels are going to wanna go different speeds then your rear tires. when this happens all 4 tires try and play catch up....hopefully your tires will give (and that's what makes the chirping sound), but if your tires are high traction and won't give then something else in the drivetrain will....components like u-joints, axle shafts, t-case chain (newer styles), axle joints, hubs, etc etc will go....the first is usually your u-joints and then hubs, but you get my point
