2) Transfer Case
(1) Planetary gear set
Planetary Gear set consists of sun gear, ring gear and carrier. It is engaged with the gear in
“HIGH-LOW” collar to increase the driving force by reducing vehicle speed.
Sun gear is connected to input shaft and ring gear is fixed into the transfer case.
Splined rear output shaft is able to slide on the “HIGH - LOW” collar.
The inside and outside ends of “HIGH - LOW” collar have machined gear. The input
shaft transmits the power to driving wheels by engaging with sun gear and carrier gear.
If the 4WD switch is at “4WD HIGH”, the TOD control unit operates the shift motor to
engage “HIGH - LOW” collar directly with input shaft for transmitting the driving force
to front and rear propeller shafts.
When a driver selects “4WD LOW”, the TOD control unit controls the electro-
magnetic clutch and operates the shift motor to engage “HIGH - LOW” collar with
carrier.
The power from transmission is increased up to 2.48:1 by reduction ratio from planetary
gear, and then is sent to front and rear propeller shafts. null
(2) Ball type slant cam and clutch
disc pack
If the speed sensors installed on front and
rear propeller shafts detect the slips at front
and rear wheels, and these slips exceed
the specified range, TOD control unit
controls electromagnetic clutch to transmit
driving force to front wheels.
At this time, ball slant cam is moved to
compress multi-disc located in clutch disc to
transmit driving force to front wheels.

1. PROPELLER SHAFT GENERAL INFORMATION
The propeller shaft transfers the power through the
transmission and transfer case to the front/rear axle
differential carrier (final reduction gear). It is
manufactured by a thin rounded steel pipe to have
the strong resisting force against the torsion and
bending. Both ends of propeller shaft are connected
to the spider and the center of propeller shaft is
connected to the spline to accommodate the
changes of the height and length. The rubbe
r
bushing that covers the intermediate bearing keeps
the balance of rear propeller shaft and absorbs its
vibration.
