FRONT AXLE -General Information26-2
GENERAL INFORMATION
The front axle consists of front hubs, knuckles,
wheel bearings and drive shafts, and it has the
following features.
DThe wheel beearing is unit bearing integrated
with hub (Double-row angular contact ball
bearing).
DThe drive shaft incorporates B.J.-T.J. type
constant velocity joints with high transmission
efficiency and low vibration and noise.DABS rotors for detecting the wheel speeds are
press-fitted to the B.J. outer wheels in vehicles
with ABS or ACD.

CARRIER ASSEMBLY INSTALLATION
Tighten the rear crossmember mounting bolts in the numerical
order shown.
NOTE
To ensure both good installation accuracy and ease of
installation, the rear crossmember mounting holes have
different diameters between front and rear. This is the reason
for specifying the tightening sequence of the mounting bolts.

AA"SELF-LOCKING NUT REMOVAL
1. Use the special tools to compress the coil spring.
Caution
(1) Do not tighten the special tool bolt too tight. The
special tool will be broken if the allowable
tightening torque of 74 N·m is exceed.
(2) Install the special tools evenly, and so that the
maximum length will be attained within the
installation range.
(3) Do not use an impact wrench as it will cause the
bolt of the special tool to be seized.
2. Using the special tools, loosen the self-locking nut.
Caution
To prevent the piston rod lock nut inside the strut
from loosening, do not use an impact wrench when
the self-locking nut is loosened.
