Unit Repair
Disassembling Unit
1) Hold differential assembly securely and put identification
marks on differential side bearing caps (6).
2) Take off differential side bearing lock plates (4) and differen-
tial side bearing caps (6) by removing their bolts and then
take out bearing adjusters (5), side bearing outer races and
drive bevel gear with differential case.
3) Remove drive bevel gear (hypoid gear), differential gears,
differential pinions and pinion shafts.
a) With aluminum plates (2) placed on vise first, grip differen-
tial case with it and remove drive bevel gear (hypoid gear)
(3) by removing its bolts (1).

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in FOREWORD of this manual.
