Can a 4WD vehicle have two locking differentials?
A 4WD vehicle that has two locking differentials provides true 4WD — all four wheels turn with the same amount of power no matter the situation. Even if the wheels on one side of your vehicle are completely off the ground, the wheels that are still on the ground will still continue to get a steady amount of torque.
Where is the transfer case on a 4WD?
Without a transfer case, your part-time 4WD vehicle would be a 2WD vehicle. The transfer case (also called the T-case) is what splits power from the engine 50/50 to both the rear and front axles by way of the front and rear drive shafts. The transfer usually sits right behind the transmission in your drivetrain.
How does a four wheel drive differential work?
From there, one driveshaft turns the front axle, and another turns the rear axle. When four-wheel drive is engaged, the transfer case locks the front driveshaft to the rear driveshaft, so each axle receives half of the torque coming from the engine. At the same time, the front hubs lock. The front and rear axles each have an open differential.
How does 4WD work in a front wheel drive car?
When 4WD is engaged, the transfer case splits the torque 50/50 between the front and rear drive shafts. The front drive shaft spins at the same speed as the rear drive shaft, transferring torque to the front differential.
