4. IWE LOCKING HUB SYSTEM
1) Overview
The vacuum locking hub uses the IWE (Integrated Wheel End) system, and in this system, the 
vacuum is generated only within the hub actuator.
It is structured to transmit power to the front section after the actuator hub is engaged following 
the release of vacuum from the drive shaft end gear and the hub end gear

2) Vacuum System Related to 4WD
During 2WD mode, the vacuum 
pressure from vacuum pump is 
continuously transmitted to the 
locking hub system.
This vacuum pressure pulls in 
the locking hub actuator so that 
it will not be engaged with the 
front end hub gear.
22WD (applying vacuum pressure to hub 
actuator) The vacuum pressure pulls in the 
locking hub actuator so that it will not be 
engaged with the front end hub gear.The vacuum pressure is released from 
the hub actuator. At this time, the front 
hub end gear is engaged.

In 4WD mode, the TCCU blocks the transferring 
of vacuum pressure from vacuum pump to 
locking hub by supplying the power to solenoid 
valve.
