Not sure what's involved to disconnect it (never had one ), just that MOST folks add that ability. It *will* help the front axle (both tires) stay in contact with the ground better... and reduce the teetering effect from the suspension.

Airing down (from street pressure to maybe 15#) to create a larger contact patch will aid traction, especially in the sand...

Or, there's always the slippery slope of traction devices! Spend money, drive harder stuff than you could open, break, spend more money upgrading, drive, break, spend... never ending cycle!
