When force is applied to the locker thats when it locks up harder, there are big springs and pins in there that will allow the wheels to differentiate, but it results in a bang. So coasting through your corners will help that a lot.

This is the main reason I went with ARB air locking differentials in my Jeep TJ so that I don't have to worry about that.

If you want to take it out, just buy an open carrier with spider gears for it, have a gear shop swap the new ring gear on the new carrier, then sell the locker.
