OUTLINE OF CONSTRUCTION
l
Full-Time 4-Wheel-Drive, incorporating an electronically controlled, lockable center differential, is standard
on the 1990 323 4WD. With this system all driving conditions are easily contended with; from good road
to bad roads and inclement weather.
l
The transaxle and transfer unit were developed based on the transaxle of the 1989 323 4WD. The trans-
axle, center differential, and front differential are a single compact unit.
l
The center differential employs a planetary carrier system, and functions to distribute the driving force
to the front and rear differentials.
Through the use of this center differential, tire scuffing common to 4-wheel-drive vehicles during tight cor-
nering, is eliminated.
l
The speedometer driven gear (for detection of vehicle speed) is installed in the transfer carrier and detects
the speed of the rear wheels.
l
Lubrication oil of the transaxle and transfer unit and the carrier is contained separately.
l
A cable shift control is used in order to reduce weight and vibration.
