4Runners with the electric locking differential should only engage it when you lose (or will lose) traction. Leaving it engaged all the time is harder on the drivetrain, tires and axle seals not to mention increasing turning radius. Most times the locker is only needed for brief periods.


I think he is talking about the center diff lock, Aka AWD/4WD, not the rear diff.
