CAUTION:
Do not run engine when one wheel (rear) is off the ground.
Preparation for Disassembly
CHECKING DIFFERENTIAL TORQUE
Measure differential torque with Tool.
If it is not within the speci®cations, inspect components of limited
slip differential.
Differential torque:
108 - 137 Nzm (11 - 14 kg-m, 80 - 101 ft-lb)

10. Install differential case A on differential case B. Align the match-
ing marks on the cases, then install screws while pushing dif-
ferential case down using a press.
Press force:
7,846 N (800 kg, 1,764 lb)
11. After all parts have been assembled, check and adjust the fol-
lowing:
DIFFERENTIAL TORQUE INSPECTION
a. Place side gear in a vise with Tool into the gear splines.
b. Turn side gear several times, then measure the differential
torque after side gear begins to rotate in order to determine
whether it is within the speci®ed range. If it is not, adjust it by
selecting a friction disc. (Refer to SDS for adjustment parts.)
Differential torque:
108 - 137 Nzm (11 - 14 kg-m, 80 - 101 ft-lb)
Tool number: KV38106400
SIDE GEAR BACKLASH INSPECTION
Check backlash of side gear on both sides. Using a feeler gauge,
measure clearance between side gear and thrust washer. If it is not
within speci®cations, adjust it by selecting a thrust washer. (Refer
to SDS.)
Side gear backlash:
Differential case A side
0.05 - 0.20 mm (0.0020 - 0.0079 in)
Differential case B side
0.05 - 0.20 mm (0.0020 - 0.0079 in)
12. After checking and adjusting, tighten ring gear bolts in a criss-
cross fashion.
13. Bend up lock straps to lock bolts in place.
14. Install side bearing inner race with Tool.

6. Install drive pinion bearing spacer, pinion bearing adjusting
shim and drive pinion in gear carrier.
7. Insert companion ¯ange into drive pinion by tapping the com-
panion ¯ange with a soft hammer.
8. Tighten pinion nut to the speci®ed torque.
The threaded portion of drive pinion and pinion nut should be
free from oil or grease.
Tool number: KV38104700
9. Turn drive pinion in both directions several times, and measure
pinion bearing preload.
Tool number: ST3127S000
Pinion bearing preload (with front oil seal):
1.4 - 1.7 Nzm (14 - 17 kg-cm, 12 - 15 in-lb)
If preload is out of speci®cation, adjust the thickness of spacer and
shim combination by replacing shim and spacer with thinner one.
+Start from the combination of thickest spacer and shim.
+Combine each spacer and shim thickness one by one until the
correct speci®cation are achieved.
Drive pinion bearing preload adjusting spacer and
shim:
Refer to SDS (PD-51).
