(e) Place matchmarks on the transmission companion
flange and propeller shaft flange.
(f) Remove the 4 washers and nuts.
(g) Remove the 2 center support bearing set bolts and ad-
justing washers.
HINT:
Some vehicles are not equipped with and adjusting washer.
NOTICE:
When removing the set bolts, support the center support
bearing by hand so that the transmission and intermediate
shaft, and propeller shaft and differential, remain in a
straight line.
(h) Remove the propeller shaft from the transmission.
(i) Push the rear propeller shaft straight forward to compress
the propeller shaft and pull out the propeller shaft from the
centering pin of the differential.
NOTICE:
Press the propeller shaft straight ahead to keep the trans-
mission and intermediate shaft aligned straight.
(j) Pull the propeller shaft out toward the vehicle's rear.
NOTICE:
The intermediate shaft and propeller shaft should not be
separated.

DIFFERENTIAL
1. General
A differential gear ratio has been changed on the 2JZ±GE engine model.
A Helical gear type torque±sensing LSD (Limited Slip Differential) is available as an option on the SJZ±GE engine
model and 2JZ±GTE engine with automatic transmission model.
As in the '96 model, a worm gear type torque±sensing LSD is used on the model with the SJZ±GTE engine and
manual transmission.

Characteristics
Good traction of high bias ratio design is obtained through the utilization of two types of friction: One is the friction
that is generated between the planet gear's tooth tips and the differential case's inner wall. The other is the friction
that is generated between the side gear end face and the thrust washer.
Quick response and minimum time lag until differential limiting force is generated.
The bias ratio sustains minimal changes due to aging and maintains a stable performance.
A simple, compact, and lightweight differential configuration has been achieved through the use of the helical gear.
Ordinary differential oil must be used; do not use special LSD oil.

27 SUPRAÐNEW FEATURES
Construction
The helical gear type torque±sensing LSD consists of a differential case, 9 planet gears, 2 side gears and 4 thrust
washers.
Planet gears mesh with one another as a pair, and each gear of the pair meshes with the side gear on its right or left
side.
The planet gears are supported by the hole that is provided in the differential case. They are constructed so that they
revolve while rotating over the side gear.
Operation
1) Straight±Ahead Operation
Since side gears (left and right) and planet gears are rotating together with the differential case as a unit when the
vehicle is running straight±forward, the driving force is transmitted from the ring gear to the differential case, planet
gears and side gears.

28SUPRAÐNEW FEATURES
2) Cornering
Supposing that the differential case is not moving, rotating the left side gear counterclockwise, causes planet gear
A (which meshes with the left side gear) to rotate clockwise.
Furthermore, planet gear B, which is paired with planet gear A, rotates counterclockwise, causing the right side gear
(which meshes with planet gear B) to rotate clockwise.
Therefore the left and right side gears rotate in the opposite direction each other, thus accomplishing a motion
differential.
3) Limited Slip Differential Operation
Limited slip is accomplished primarily b the friction that is generated between the planet gear's tooth tips and the
differential case's inner wall, and the friction that is generated between the side gear end face and the thrust washer.
The principle of limited slip enables the resultant reaction force F1 (which is created by the meshing reaction of the
planet gear and the side gear and the meshing reaction of the planet gears themselves) to push the planet gear in the
direction of the differential case in proportion to the input torque.
Due to the reaction force F1, the friction force u F2 (which is generated between the side gear end face and the thrust
washer) applies a force to cancel out the rotational difference between the side gears themselves as well as between
the side gear and the differential case.

type seats without changing their basic design.
4. 2JZ±GTE Engine
An aluminum radiator core is adopted for weight reduction.
5. Differential
A differential gear ratio has been changed on he 2JZ±GE engine model.
A helical gear type torque±sensing LSD is available as an option on the 2JZ±GE engine model and 2JZ±GTE engine
