The propeller shaft is a 3-section 4-joint shaft with 2
center bearings. This division into 3 sections
increases the vibration frequency characteristics of
the shaft bending, and reduces vibration and noise
when driving at high speed. The joints for connecting
each part of the propeller shaft are as follows; No.1,
No.2 and No. 4 joints are cross type universal joints
and No.3 joint is a Lobro joint (LJ) that can slide and
has small friction in the direction of the shaft. This
structure helps reducing torque fluctuation, vibration
and noise. Furthermore, the rear propeller shaft is a
vibration-control type shaft (using rubber) with an
inner tube inserted in the outer tube to reduce
vibration and noise from the drive train.

NOTE
Propeller shaft length indicates the length between center points of each joint.
