E = 0.10 mm, F 0.15 mm
Left side

= (5 + 3 + 4 - 3)
x
0.01 + 0.76 - 0.10
= 0.09 + 0.76 - 0.10
= 0.75 mm
The correct shims are as follows

(3) Install the differential case ASSY into differential
carrier in the reverse order of disassembling.
(4) Fit the selected shims and a·ring on side bearing
retainer and install them on differential carrier with the
arrow mark on the retainer directed as shown in Figure.
Be careful that side bearing cup is not damaged by bearing
roller.

(5) Tighten side bearing retai ner bolts.
On vehicle with LSD, apply a coat of Three Bond 1215 (PIN
004403007) to threads.
Torque (Side bearing retainer):
9 - 12 N'm (0.9 - 1.2 kg-m, 6.5 - 8.7 ft-Ib)
(6) Measure the drive gear·to·drive pinion backlash.
If the reading is not within the specified range, correct bV
decreasing the shim thickness on one side and increasing
the shim thickness on the other side the same amount.
Total shim thickness must be the same to maintain proper
preload.
Backlash:
0.10 - 0.20 mm (0.0039 - 0.0079 in)
