2004 NISSAN TERRANO Service Repair Manual

Differential Carrier
1. Mount final drive assembly on Tool.Tool number:ST06340000
2. Put match marks on one side bearing cap with paint or punch to ensure that it is replaced in proper position during reassem-
bly.
Bearing caps are line-bored during manufacture and should
be put back in their original places.
3. Remove side lock fingers and side bearing caps.
4. Remove side bearing adjuster with Tool. Tool number:ST32580000
5. Remove differential case assembly with a pry bar.

Be careful to keep the side bearing outer races together with
their respective inner cones Ð do not mix them up.
6. Remove drive pinion nut with Tool.Tool number: KV38104700
7. Remove companion flange with puller.
8. Take out drive pinion together with pinion rear bearing inner cone, drive pinion bearing spacer and pinion bearing adjusting
shim.
9. Remove front oil seal and pinion front bearing inner cone.
10. Remove pinion bearing outer races with a brass drift.

11. Remove pinion rear bearing inner cone and drive pinion adjust-ing washer.Tool number: ST30031000
Differential Case
1. Remove side bearing inner cones.
To prevent damage to bearing, engage puller jaws in groove. Tool number:q

Be careful not to confuse left and right hand parts.
2. Loosen ring gear bolts in a criss-cross fashion.
3. Tap ring gear off differential case with a soft hammer.
Tap evenly all around to keep ring gear from binding.

Ring Gear and Drive Pinion
Check gear teeth for scoring, cracking or chipping.
If any damaged part is evident, replace ring gear and drive pinion
as a set (hypoid gear set).
Differential Case Assembly
Check mating surfaces of differential case, side gears, pinion mate
gears, pinion mate shaft, and thrust washers.
Bearing
1. Thoroughly clean bearing.
2. Check bearings for wear, scratches, pitting or flaking.Check tapered roller bearing for smooth rotation. If damaged,
replace outer race and inner cone as a set.

CAUTION:
Do not run engine when one rear wheel is off the ground.
Preparation for Disassembly
CHECKING DIFFERENTIAL TORQUE
Measure differential torque with Tool.
If it is not within the specifications, inspect components of limited
slip differential.Differential torque:353 - 392 N×m (36 - 40 kg-m, 260 - 289 ft-lb)

Disassembly
1. Spread out lock straps.
2. Remove couple bolts using a press.Tool number: ST33081000
3. Separate differential case A and B. Draw out component parts (discs and plates, etc.)
Put marks on gears and pressure rings so that they can be
reinstalled in their original positions from which they were
removed.
Inspection
CONTACT SURFACES
1. Clean the disassembled parts in suitable solvent and blow dry with compressed air.
2. If following surfaces are found with burrs or scratches, smooth with oil stone.

DISC AND PLATE
1. Clean the discs and plates in suitable solvent and blow dry with
compressed air.
2. Inspect discs and plates for wear, nicks and burrs.
3. To make sure that friction disc or plate is not distorted, place it on a surface plate and rotate it by hand with indicating finger
of dial gauge resting against disc or plate surface. Check the
warpage.Allowable warpage: 0.05 - 0.15 mm (0.0020 - 0.0059 in)
If it exceeds limit, replace with a new plate to eliminate possi-
bility of clutch slippage or sticking.

4. Measure frictional surfaces and projected portions of frictiondisc, friction plate and spring plate.
If any part has worn beyond the wear limit, replace it with a new
one that is the same thickness as the projected portion. Wear limit:0.1 mm (0.004 in) or less
Adjustment
FRICTION DISC AND FRICTION PLATE END PLAY
End play of friction disc and friction plate can be calculated by using
the following equation and should be adjusted within the following
range.
Adjustment can be made by selecting friction disc having two dif-
ferent thicknesses. End play E:0.05 - 0.15 mm (0.0020 - 0.0059 in)
E=Aþ(B+C)
A: Length of differential case contact surface to differential case inner bottom.
B: Total thickness of friction discs, friction plates, spring disc and spring plate in differential case on one side.
C: Length of differential case contact surface to back side of side gear.
1. Measure values of ªAº. Standard length A:49.50 - 49.55 mm (1.9488 - 1.9508 in)
