Components of IWE (Integrated Wheel End)
Front Hub Assembly
The front hub assembly is connected to the tire and it drives the wheel by receiving the rotation
force from the drive shaft during 4WD mode. When the hub actuator is moved to the gear (vacuum
pressure released), the 4WD mode is engaged. When the hub actuator is out of the gear (vacuum
pressure applied), the 4WD mode is concelled.
Replace it with a new one when removing.
Function: preventing moisture and foreign
matter from entering into gears.
Front Drive Shaft
The front drive shaft is the part that receives the power when the transfer case operates in 4WD
mode. During the 2WD mode, the hub actuator is positioned at the drive shaft end, and during the
4WD mode, the hub actuator is interlocked to the drive shaft end gear and the front hub end gear.
