WHEELS AND AXLES
M MECHANISM AND FUNCTION
1 . Front Axle
~
A: GENERAL
The inboard end of the axle shaft is connected to the
transmission via a constant velocity joint (Free-ring
tripod joint : FTJ) which provides flexible capabilities in
the longitudinal direction while the outboard end is
supported by taper roller bearings located inside the
housing via a bell joint (BJ) which features a large
operating angle.
Since the drive shaft employs constant velocity joints, it
provides smooth, even rotation of the drive wheels
without any vibration .
The bearing utilizes a preloaded, non-adjustable ta-
pered roller unit design.
The hub is fitted to the tapered roller bearing inside the
housing. The BJ's spindle is "serration-fitted" to the hub
and is clinched to it with axle nuts . After front axle parts
have been repaired, toe-in should be adjusted .
The disc rotor is an external mounting type . It is secured
together with the disc wheel using hub bolts to facilitate
maintenance of the disc rotor.
