Thanks. Still confused, especially after talking with a REMCO Drive Shaft installer here in Salem who wasn't completely reassuring when it came to the fact that my 2013 Nissan Truck is an optional 4X4 wheel drive vehicle and wasn't sure how the drive shaft being disconnected would affect the front wheel drive mechanisms. The concept is, if the main drive Shaft is disconnected using his REMCO coupler, with the automatic transmission in Park, it will not be functioning and no damage would occur. How's that sound?
