Locking diffs. unite the drive wheels into one unit.  When you turn a corner
both wheels will be forced to rotate exactly the same amount, but over the
ground, the wheel on the 'inside' travels a shorter distance than the
outside wheel.  So one or the other of the wheels will be forced to 'skid'
across the pavement.  Odd handling behavior, diminished tire life and broken
differentials can result.  Excellent traction, however, and no wear and tear
problems when used on loose surfaces like snow or sand.
