Viscous Coupling Check

1. Apply parking brake firmly and place shift lever in the neutral position.

2. Jack up front wheels.

3. Rotate one front wheel and check turning direction of the other front wheel.

Turning direction of the two wheels is opposite:

The viscous coupling is not functioning normally.

Turning direction of the two wheels is the same:

If differential side gear and pinion mate gear thrust washers are OK, viscous coupling is functioning normally.
