When did Toyota start using front wheel disengage?
Applications date back to the early 1980s for the domestic trucks, and as far back as 1976 for Toyota.

What happens when you engage 4WD on a Dodge?
When you engage 4wd, a synchronizer in the transfercase spins up the front driveshaft; at the same time, a vacuum switch opens, causing the vacuum motor in the CAD to try and lock together the right axle shafts. Engagement does not occur until the splines on the shaft lines up with the ones on the sleeve.
What happens when the transfer case is switched to 4WD?
But as long as the transfer case remains in the 2WD mode, the front wheels are not driven. When the transfer case is shifted into 4WD, the unlocked hub automatically slides into position and locks the axle so both front wheels become drive wheels.
How does disconnecting the front wheels improve fuel economy?
