Checking Differential Gear Oil
1. Check differential carrier for oil leakage.
2. Check oil level.Filler plug:
:59-98N zm (6 - 10 kg-m, 43 - 72 ft-lb)
Changing Differential Gear Oil
Oil capacity:
Front5.4 liters (9-1/2 Imp pt)
Rear H233B (Without diff. lock) 2.4 liters(4-1/4 Imppt)
H233B (With diff. lock) 3.0 liters (5-1/4 Imp pt)
H260 (Without diff. lock) 4.7 liters (8-1/4 Imp pt)
H260 (With diff. lock) 3.7 liters (6-1/2 Imp pt)
Drain plug:
:59-98N zm (6 - 10 kg-m, 43 - 72 ft-lb)
Limited-slip differential gear
+ Use only approved or recommended limited-slip differential
gear oil.
+ Limited-slip differential identi®cation.
(1) Lift both rear wheels off the ground.
(2) Turn one rear wheel by hand.
(3) If both rear wheels turn in the same direction simultaneously, vehicle is equipped with limited-slip differential.
Checking Front Wheel Bearing Grease
+Check that wheel bearings operate smoothly.
+ Check front wheel bearings for grease leakage and water or
dust entry.
+ Replace front wheel bearings or front wheel bearing grease if
wheel bearings do not turn smoothly.

Repacking Front Wheel Bearing and Axle Joint
Grease
FRONT WHEEL BEARING GREASE
Apply multi-purpose grease sparingly to the following parts:
+Threaded portion of spindle
+Contact surface between wheel bearing washer and outer
wheel bearing
+Grease seal lip
+Wheel hub (as shown at the left)
AXLE JOINT GREASE
+Drain approximately 2 liters (1-3/4 Imp qt) of differential oil.
+Remove knuckle spindle.
+Slightly pull out axle and repack axle joint with recommended
grease.
Refer to FA section.
Checking Free-running Hub Grease
Check free-running hub grease for leakage and water or dust entry.
Checking Water Entry in Knuckle Flange
+Check for water entry in knuckle ¯ange by removing one bolt
of lower knuckle ¯ange bearing cap and probing with a suitable
thin bar.
+After checking, be sure to reinstall the bolt to a tightening torque
of 30 to 40 Nzm (3.1 to 4.1 kg-m, 22 to 30 ft-lb).
Checking Brake Fluid Level and Leaks
If ¯uid level is extremely low, check brake system for leaks.
