4H (4WD High) Position

WARNING: This page is about a different car, the 2006 Suzuki XL-7. However, it is still accessible from the selected car via links, so may be relevant.

When 4H position is selected from 2H position by pressing the 2WD/4WD switch, the transfer shift control actuator motor runs and both reduction drive shift cam and front drive shift cam rotate in the arrow direction "C". The front drive shift shaft shifts in the arrow direction "A" by the front drive shift cam, and the front drive clutch sleeve moves in the arrow direction "B".

The driving force from the transmission is transmitted from the transfer input gear to the output rear shaft, as in the case of 2H position. Also, as the front drive clutch hub and front drive sprocket are engaged via front drive clutch sleeve, the driving force is transmitted to the front drive sprocket.

Then, the front drive sprocket rotates the front output shaft via the drive chain.
