For new differential pinion bearings, tighten the nut to specification. Refer to torque
specifications for new differential pinion bearings in the Specifications portion of this
section.
z For used differential pinion bearings, if the preload recorded prior to disassembly is lower
than the specification for used bearings, then tighten the nut to specification. Refer to
torque specifications for used differential pinion bearings in the Specifications portion of
this section.
z For used differential pinion bearings, if the preload recorded prior to disassembly is
higher than the specification for used bearings, then tighten the nut to the original reading
as recorded.
Final assembly 23. Install the differential assembly in the differential housing. For additional information, refer to Differential Case in this section.
24. CAUTION: Align the index marks.

M2G351- A5 to the threads of the original bolts.
CAUTION: The driveshaft centering socket yoke fits tightly on the pinion flange
pilot. To make sure that the yoke seats squarely on the flange, tighten the bolts evenly in
a cross pattern as shown.
Connect the driveshaft. For additional information, refer to Section 205 - 01 .

CAUTION: Do not under any circumstance loosen the nut to reduce preload. If it is
necessary to reduce preload, install a new differential drive pinion collapsible spacer
(4662) and nut.
Tighten the nut to set the preload.
zRotate the pinion occasionally to make sure the pinion bearings (4630) (4621) seat
correctly. Take frequent pinion bearing torque preload readings by rotating the drive
pinion gear with a Nm (inch/pound) torque wrench.
z If the preload recorded prior to disassembly is lower than the specification for used
bearings, then tighten the nut to specification. If the preload recorded prior to
disassembly is higher than the specification for used bearings, then tighten the nut to the
original reading as recorded.
z Refer to the torque specification for used pinion bearings in the Specifications portion of
this section.

GENERAL PROCEDURES
Supplemental Restraint System (SRS) Deactivation and
Reactivation
Deactivation
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint
system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury
in the event of an accidental deployment.
WARNING: After deployment, the air bag surface can contain deposits of sodium
hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your
hands with soap and water afterwards.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air
bag deployment, which can result in personal injury.
WARNING: Air bag modules with discolored or damaged trim covers must be installed
new, not repainted.
WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and possible
violation of vehicle safety standards.
1. WARNING: To avoid accidental deployment and possible personal injury, the
backup power supply must be depleted before repairing or replacing any front or side air
bag supplemental restraint system (SRS) components and before servicing, replacing,
adjusting or striking components near the front or side air bag sensors, such as doors,
instrument panel, console, door latches, strikers, seats and hood latches.
Please refer to the appropriate vehicle shop manual to determine location of the front air
bag sensors.
The side air bag sensors are located at or near the base of the B- pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and
wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). SECTION 211-

3. Make sure the valve tappet is seated against camshaft (6250). Install (1) Dial Indicator Gauge with Holding Fixture so the ball socket adapter of the indicator is on top of the valve tappet or (2)
Dial Indicator Gauge Adapter is on top of push rod and in same plane as valve tappet push rod
movement.
4. Remove the spark plugs.
5. Connect an auxiliary starter switch in the starting circuit. Crank the engine with ignition switch in OFF position. Bump crankshaft over until valve tappet is on base circle of camshaft lobe. At this
point, valve tappet will be in its lowest position. If checking during engine assembly, turn
crankshaft using a socket or ratchet.

position (highest indicator reading).
7. NOTE: If lift on any lobe is below specified service limits, install a new camshaft, and new valve
tappets.
