What cars have viscous couplers?
Viscous couplings are used as the center differential in cars such as the Toyota Celica GT-Four, and also as a limited slip differential (LSD) in rear axles. They offer a cheaper way to implement four-wheel-drive than technologies like the mechanical-transfer Torsen differentials used by Audis.
What is a viscous transfer case?
The viscous coupling is often found in all-wheel-drive vehicles. It is commonly used to link the back wheels to the front wheels so that when one set of wheels starts to slip, torque will be transferred to the other set. This transfers more torque to the slower moving wheels — the wheels that are not slipping.
How is viscous coupling used in all wheel drive?
The viscous coupling is often found in all-wheel-drive vehicles. It is commonly used to link the back wheels to the front wheels so that when one set of wheels starts to slip, torque will be transferred to the other set. The viscous coupling has two sets of plates inside a sealed housing that is filled with a thick fluid,…
Where are CV joints located on a car?
You will find CV joints in all-wheel drive and front-wheel drive vehicles. As for rear-wheel drive vehicles that have separate rear suspensions, the half-shafts’ ends of the rear axle will have CV joints in them.
Why does a Syncro Vanagon have a viscous coupler?
All Syncro Vanagons were originally fitted with a device called a viscous coupler (VC) which allows them to be in full-time “kinda” 4WD. The purpose of the viscous coupler is to allow slippage between the front and rear axles when the vehicle is driven in high traction situations. For example, when doing tight maneuvering in a dry parking lot.
Can a bad CV joint cause a car to vibrate?
You likely have a faulty CV joint i f you’re driving on a flat paved road and your vehicle is still bouncing around. You can verify this by going to an auto shop that repairs transmissions. A worn or damaged CV joint will vibrate while you’re driving.
How does viscous coupling work in all wheel drive?
In this case, in normal conditions, all power is transferred to just one axle. One part of the viscous coupling is connected to the driving axle, another part is connected to the driven axle. When driving wheels slip, viscous coupling locks and torque is transferred to the other axle. This is an automatic all wheel drive system.
Which is the first car with a viscous coupling?
The first mass-produced viscous couplings for a permanent 4WD off-road-capable vehicle was in the AMC Eagle, which was produced from 1980 to 1988 model years. The AMC Eagle’s single-speed model 119 New Process central differential used a viscous coupling filled with a liquid silicone-based material.

What are the disadvantages of viscous coupling?
When driving wheels slip, viscous coupling locks and torque is transferred to the other axle. This is an automatic all wheel drive system. The disadvantage of a viscous coupling is that it engages too slowly and allows for excessive wheelspin before transferring torque to another wheels.
