Drive Shaft System

2. Front Axle

A: GENERAL
! The inboard end of each axle shaft is connected to the transmission via a constant velocity joint
(shudder-less freering tripod joint: SFJ) which is flexible in the axial directions while the outboard
end is connected via a bell joint (BJ) to the wheel hub which is supported by a taper roller bearing
located inside the axle housing. The BJ features a large operating angle.
Both the constant velocity joints (SFJ and BJ) ensure smooth, regular rotation of the drive wheels
with minimum vibration.
! The bearing is a preloaded, non-adjustable tapered roller unit bearing.
Each hub is fitted in the axle housing via the tapered roller bearing.
The BJ's spindle is splined to the hub and is secured with an axle nut clinched to it.
!
! The disc rotor is an external mounting type. It is secured to the disc wheel using hub bolts to
facilitate maintenance of the disc rotor.
! The axle nuts are given chromate treatment (olive drab treatment).
