2001 SUZUKI GRAND VITARA ect

7F-18 DIFFERENTIAL (REAR)
Assembling Unit
1) Place bearing outer races on their respective bearings.
Used left and right outer races are not interchangeable.
2) Install case assembly in carrier.
3) Install side bearing adjusters on their respective carrier,
making sure adjuster are threaded properly.
4) Align match marks (1) on cap and carrier. Screw in 2 side
bearing cap bolts 2 or 3 turns and press down bearing cap
by hand.
5) Tighten cap bolts (provisional torque).
Tightening torque
Bearing cap bolt (Provisional torque) (a) :
15 N·m (1.5 kg-m, 11.0 lb-ft)
6) Tighten both bearing adjusters (2) so as to obtain specified
gear backlash and at the same time, obtain preload of side
bearing.
Standard backlash
: 0.13 – 0.18 mm (0.005 – 0.007 in.)
Special tool
(A) : 09930-40120
(B) : 09930-40113
(C) : 09900-20701
NOTE:
If bearing cap does not fit tightly on carrier, side bearing
adjuster is not threaded properly. Reinstall adjuster.
NOTE:
Be sure to apply measuring tip of dial gauge at right
angles to convex side of tooth.
As a practical measure the following would be recom-
mended to obtain specified backlash and side bearing
preload at the same time.
–Obtain specified backlash by turning both adjusters
inward lightly.
–Tighten both adjusters further by one notch at a
time.
Measure at least 4 points on drive bevel gear periph-
ery.

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.

General Description
WIRE COLOR SYMBOLS
There are two kinds of colored wire used in this vehicle. One is
single-colored wire and the other is dual-colored (striped) wire.
The single-colored wire uses only one color symbol (i.e. “GRN”).
The dual-colored wire uses two color symbols (i.e. “GRN/YEL”).
The first symbol represents the base color of the wire (“GRN” in
the figure) and the second symbol represents the color of the
stripe (“YEL” in the figure). Symbol Wire Color Symbol Wire Color
