1. REAR DIFFERENTIAL
When replacing a rear differential assembly, select the correct one according to the following table.
NOTE:
•Using a different rear differential assembly will cause the drive train and tires to drag or emit abnormal
noise.
•For option code, refer to “ID” section.
2. IDENTIFICATION
Identification label positions are shown in the fol-
lowing figures. For details concerning identification,
refer to the “ID” section.

C: DISASSEMBLY
Using the ST and a hydraulic press, push out the
hub bolts.
ST 28399AG000 HUB STAND
CAUTION:
•Be careful not to hammer the hub bolts. This
may deform the hub.
•Do not reuse the hub bolt.
NOTE:
Since the hub unit bearing can not be disassem-
bled, only hub bolts can be removed.
D: ASSEMBLY
1) Attach the hub to the ST securely.

2) Using a press, press the new hub bolts until their
seating surfaces contact the hub.
NOTE:
Use the 12 mm (0.47 in) dia. holes in the HUB
STAND to prevent bolts from tilting.
E: INSPECTION
1) Moving the rear tire up and down by hand, check
there is no backlash in bearing, and check the
wheel rotates smoothly.
2) Inspect the lean of axis direction using a dial
gauge. Replace the hub bearing if the play exceeds
the limit value.

1) Park the vehicle on a level surface.
2) Empty the vehicle so that it is at “curb weight”. (Empty the luggage compartment, load the spare tire, jack
and service tools, and fill up the fuel tank.)
3) Set the steering wheel in a straight–ahead position, and stabilize the suspension by moving the vehicle in
a straight line for more than 5 m (16 ft).
4) Suspend a thread from the wheel arch (point “A” in the figure below) and affix at a position directly above
the center of wheel.
5) Measure the distance between the point “A” and the center of wheel.

Brake grease:
Brake Grease (Part No. 003602002)
•Six contact surfaces of brake shoe rim and back
plate gasket
•Contact surface of the brake shoe and the an-
chor pin
•Contact surface of the lever and strut
•Contact surface of the brake shoe and the ad-
juster assembly
•Contact surface of the brake shoe and the strut
•Contact surface of the lever and brake shoe
2) Install in the reverse order of removal.

Brake).>
4) Drive the vehicle to break-in the parking brake
lining.
(1) Drive the vehicle at about 35 km/h (22
MPH).
