INSTALLATION SERVICE POINT
"AACASTLE NUT INSTALLATION
1. Be sure to install the castle nut washer in the specified
direction.
2. Using the special tool, tighten the castle nut.
Caution
Before securely tightening the castle nuts, make sure
there is no load on the wheel bearings. Otherwise
wheel bearing will be damaged.
INSPECTION
INSPECTION OF WHELL BEARING ROTATION STARTING
TORQUE
1. Tighten special tools in hub and knuckle assembly to
the specified torque.
2. Measure the wheel bearing rotation starting torque with
special tools.
Limit: 1.03 N·m or less
3. Wheel bearing rotation starting torque must be under
the limit value and there should be no roughness when
rotating the hub.
WHEEL BEARING AXLE PLAY CHECK
1. Secure knuckle in a vice to measure axle play in wheel
bearing.
Limit: 0.06 mm
2. If the limit value of wheel bearing axle plya cannot be
obtained when tightened to the specified torque (245
±29 N·m), check mounting bolt for hub and knuckle
assembly. If no defects are found, replace hub assembly.

REMOVAL AND INSTALLATION
Caution
1. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched. And
if there is brake fluid on the caliper, wipe out quickly.
2. For vehicles with ABS or ACD, do not strike the rotor for wheel speed sensor installed to
the B.J. outer race of drive shaft against other parts when removing or installing the drive
shaft. Otherwise the rotor for wheel speed sensor will be damaged.

Caution
1. Loosen the nut only; do not remove it from the ball
joint. Otherwise ball joint thread will be damaged.
2. The special tool should be suspended by a cord to
prevent it from coming off.
AB"DRIVE SHAFT REMOVAL
1. Use the special tools to push out the drive shaft from
the hub.
2. Withdraw the drive shaft from the hub by pulling the bottom
of the brake disc towards you, and then remove the hub
retaining bolts.
3. Remove the drive shaft from the transmission by the
following procedure.
Insert a pry bar between the transmission case and the
drive shaft, and then pry the drive shaft from the
transmission.
Caution
(1) Do not pull on the drive shaft; doing so will damage
the T.J.; be sure to use the pry bar.
(2) When pulling the drive shaft out from the
transmission, be careful that the spline part of
the drive shaft does not damage the oil seal.
(3) Do not apply the vehicle weight to the wheel
bearing while loosening the drive shaft nut.
Otherwise wheel bearing will be damaged. If,
however, the vehicle weight must be applied to
the bearing (because of moving the vehicle),
temporarily secure the wheel bearing by using
the special tool.

DISASSEMBLY AND REASSEMBLY
Caution
(1) On the vehicles with ABS or ACD, when the drive shaft is disassembled or reassembled, be
careful not to interfere with the rotor for wheel speed sensor installed to the B.J. outer race
to prevent the rotor from damage.
(2) Never disassemble the B.J. assembly except when replacing the B.J. boot.

REAR AXLE -General Information27B-2
GENERAL INFORMATION
The rear axle consists of rear hubs, wheel bearings,
drive shafts, and rear differential and, it has the
following features.
DThe wheel bearing is a unit bearing (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.
NOTE
