I do not know if this applies to automatic or the newer transfer cases.
It is a easy and quick job to do it. when I arrive at my location I unhook the jeep, lock the front hubs, put in 4 wheel drive. Move the jeep using the front wheel drive to a location where you can reconnect the drive shaft. Takes me about 5 - 10 minutes.
This also reduces the moving parts in the transfer and tranny cases. Saves on wear and tear.
This recommendation was made in 4 Wheel Magazine about 20 years ago. They did a how to do it on welding tabs on the output shaft of the transfer case to throw oil around the inside of the transfer case during towing with the driveshaft connected.
I found it was just easier to unhook the driveshaft.
None of that is remotely applicable to the 2010 Wrangler that the OP was asking about.
