In a Syncro drivetrain, a driveshaft decoupler disconnects the prop shaft so the front axle is no longer driven through it; it is not the front differential lock. A Gerry discussion on 16 May 2004 compares the original non-viscous-coupling layout, which used a driveshaft decoupler, with viscous-coupling Syncros while debating front-lock behavior. The thread is historical community discussion, not a retrofit procedure; identify the drivetrain configuration before interpreting parts or controls.
