(7) Turn the SST (selector) to increase the clear-
ance indicated by the arrow with the SST
(bars), until it no longer turns.
Note
a) This is to seat the bearings.
b) To turn the SST (B), bend the bar as shown.
(8) Turn the selector in the opposite direction un-
til the preload is eliminated (gap is reduced).
(9) Insert the SST through the oil seal hole of the
transaxle case and attach it to the pinion shaft.
(10) Mount the SST and pull scale or torque
wrench.
(11) Widen the clearance between A and B to ob-
tain the specified preload/pull scale reading.
Preload:
0.5 N-m (5 cm-kg, 4.3 in-lb)
Reading on pull scale:
5 N (0.5 kg, 1.1 lb)
Note
Read the preload when the differential starts
to turn.
(12) Measure the clearance between A and B.
(13) Add 0.3 mm (0.0118 in) to the measured
clearance, and select the shim(s) closest in
valve to that measurement.
