TRANSFER 7D-19
NOTE:
 Be careful not to turn bevel gear more than one full
revolution, for it will hinder accurate check.
 If bevel gear back lash and bevel pinion shims are
adjusted properly, correct tooth contact should be pro-
vided.
If correct tooth contact is not provided even when they
are adjusted properly, however, there may be an
abnormal condition in worn tooth, transfer case or
retainer. Check each component and replace as neces-
sary.
TOOTH CONTACT PATTERN DIAGNOSIS AND REMEDY
NORMAL
HIGH CONTACT
Pinion is positioned too fat from the
center of drive bevel gear.
1) Decrease thickness of bevel pinion
shim and position pinion closer to
gear center.
2) Adjust drive bevel gear backlash to
specification.
LOW CONTACT
Pinion is positioned too close to the
center of drive bevel gear.
1) Increase thickness of bevel pinion
shim and position pinion farther
from gear center.
2) Adjust drive bevel gear backlash to
specification.

UNIT INSTALLATION
Install transfer assembly (2) by reversing removal procedure and
noting following points.
Tighten transfer mounting bolts (3) to specified torque.
Tightening torque
Transfer mounting bolts (a) : 50 N·m (5.0 kg-m, 36.5 lb-ft)
Tighten rear mounting bracket bolts (1) to specified torque.
Tightening torque
Transfer rear mounting bracket bolts
(a) : 55 N·m (5.5 kg-m, 40.0 lb-ft)These contact patterns indicate that the “offset” of
reduction driven gear is too much or too little. The rem-
edy is to change the division of the bevel gear shim(s).
These contact patterns, located on toe or heel on both
drive and coast sides, mean that 1) both pinion and
gear are defective, 2) retainer is not true, or 3) gear is
not properly seated on transfer case. The remedy is to
replace the defective member.
Irregular patterns: If the pattern is not oval, it means
that bevel gear is defective. High or low spots on tooth
surfaces or on the seat of bevel gear are the cause of
irregular patterns appearing on some teeth. The rem-
edy is to replace the pinion and gear set and, if the seat
is defective, so is transfer case. TOOTH CONTACT PATTERN DIAGNOSIS AND REMEDY

7F-2 REAR DIFFERENTIAL
GENERAL DESCRIPTION
The differential assembly uses a hypoid bevel pinion and gear.
The differential assembly is decisive in that the drive power is concentrated there. Therefore, use of genuine
parts and specified torque is compulsory. Further, because of sliding tooth meshing with high pressure between
bevel pinion and gear, it is mandatory to lubricate them by hypoid gear oil.
VISCOUS COUPLING
The 4WD vehicle is equipped with a viscous coupling (1) in front of the rear differential.
The 4WD mechanism used for this vehicle distributes optimum driving force to the front and rear wheels accord-
ing to road conditions and driving conditions.
