3. DUAL MASS FLYWHEEL (DMF)
The dual mass flywheel (DMF) is of having a mass divided into two halves.
While one mass is connected to the engine crankshaft, which is affected by the mass moment of inertia
of the engine, the other mass is affected by one of the transmission.
The divided dual masses are connected to the coil spring and damping system internally.
The DMF has the following benefits: ▶
Reducing fuel consumption by lowering engine speed
Reducing rattling noise and vehicle vibration in all driving ranges
Reducing synchronization wear
Facilitating gear change
Protecting power train parts by preventing excessive load from being delivered -

1. OVERVIEW
The propeller shaft is a thin steel pipe which transfers the power from the transmission to the E-coupling,
and has high resistance to torsion and bending.
The propeller shaft has the universal joint (cross axle) mounted on the center of the shaft and splines for
the slip joint on the E-coupling side to accommodate the height and length changes which occur as the
shaft rotates at high speed.
And the rubber bushing for center bearing in the center of the propeller shaft keeps the balance of the
shaft and absorbs its vibration.
Function of propeller shaft ▶
Transmits driving torque.
Accommodates the angle change (universal joint / CV joint).
Accommodates the axial length change (splines for the slip joint). -

The front sub frame consists of 4 body bush mountings(A) and 2 engine bush mountings(B) which
reduce the vibration from the powertrain and road, and also control the torque. And the two engine bush
mountings consist of an engine mounting which supports the engine powertrain and a transmission
mounting.
The engine side and transmission side mountings are rubber mountings with brackets and insulators
while the body mounting is a rubber bush mounting which is fitted to the frame.
Installation of front sub
frame (4WD)The installation of the front sub frame is the same for both automatic
transmission and manual transmission. For 4WD, the PTU and the
propeller shaft are installed.
Installation of front sub
frame (2WD)The installation of the front sub frame is the same for both automatic
transmission and manual transmission.

Installation of rear sub
frame (4WD)The installation of the rear sub frame is the same for both automatic
transmission and manual transmission. For 4WD, the E-coupling, propeller
shaft and rear axle are installed.
Installation of rear sub
frame (2WD) The installation of the rear sub frame is the same for both automatic
transmission and manual transmission.
The rear sub frame system consists of body bush mountings and direct mountings which reduce the
vibration transmitted from the powertrain and road to the vehicle body.
For 4WD, it consists of 4 body mountings (bush mountings) and 2 axle mountings (bush mountings) and
for 2WD, it consists of 4 body mountings (direct mountings).
