INSTALLATION
Note the following, and install in the reverse order of removal.

Refer to RFD-16, "Components" about each tightening torque.

When installing breather hoses, refer to the figure and following.
CAUTION:
Make sure there are no pinched or restricted areas on the
breather hose caused by bending or winding when install-
ing it.
–For installation of rear final drive breather hose, the vehicle side
end shall be inserted to cross member. Install metal connector
side of this hose to rear cover by inserting it with aiming painted
marking to the front of vehicle.
–For installation of electric controlled coupling breather hose, the
vehicle side end shall be inserted to cross member. Install its
metal tube to rear final drive assembly and direct the metal tube
hose side end to the front of vehicle.

When oil leaks while removing final drive assembly, check oil
level after the installation. Refer to RFD-8, "
Checking Differential
Gear Oil" .

ASSEMBLY
Assembly of Drive Pinion Assembly
1. Assemble with a drive pinion adjusting shim of the same thick-
ness as was installed prior to disassembly. Using the suitable
drift, press a pinion rear bearing outer race into the carrier case.
CAUTION:

At first, using a hammer, tap the bearing outer race until it
becomes square to the carrier case.

Do not reuse the pinion rear bearing outer race.
2. Using the drift below, press a pinion front bearing outer race into
the carrier case.
CAUTION:

At first, using a hammer, tap the bearing outer race until it
becomes square to the carrier case.

Do not reuse the pinion front bearing outer race.
3. Using the drift below, press a pinion rear bearing inner race into
the drive pinion.
CAUTION:
Do not reuse the pinion rear bearing inner race.
4. After checking and adjusting the tooth contact and backlash of
the hypoid gear following the procedure below, assemble a col-
lapsible spacer to the drive pinion.
CAUTION:

Be careful of the mounting direction of the collapsible
spacer.

Do not reuse the collapsible spacer.
a. Apply differential oil to the pinion rear bearing, and assemble the
drive pinion to the carrier case.

BRAKE FLUID

BRAKE FLUIDPFP:KN100
Checking Brake Fluid Level EFS000C5

Confirm reservoir tank fluid level is within the specifications
(between MAX and MIN lines).

Visually check around reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Checking Brake LineEFS001C5
CAUTION:
If leakage occurs around joints, retighten or, if necessary, replace damaged parts.
1. Check brake line (tube and hoses) for cracks, deterioration or
other damage. Replace and damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake FluidEFS000C3
CAUTION:

Refill with new brake fluid “DOT 3 or DOT 4”.

Always keep fluid level higher than minimum line on reservoir tank.

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away water immediately.
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve of each wheel while
depressing brake pedal.
3. Turn OFF ignition switch. Remove ABS actuator connector.

REFRIGERANT LINES

Checking for Refrigerant LeaksEJS000VJ
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent
dye leak detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorEJS000VK
1. Check A/C system for leaks using the UV lamp and safety goggles (J-42220) in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (J-43872) to prevent future misdiag-
nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye InjectionEJS000VL
(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.45 bar, 3.52 kg/cm
2 , 50
psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (J-41459).
3. Connect the injector tool to the A/C LOW-PRESSURE side service fitting.
4. Start engine and switch A/C ON.
5. When the A/C operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye
through the low-pressure service valve using dye injector tool J-41459 (refer to the manufacture's operat-
ing instructions).
6. With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system con-
nection and proceed with the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leak size, operating conditions and location of the leak, it may take from minutes to days for the dye to
penetrate a leak and become visible.
