7C ASSEMBLY
3. Adjust the differential side bearing preload and select the adjust shim(s) as described below.
Note
To inspect and adjust the preload, use the SST shown below.
76G07C-242
(1) Remove the side bearing housing race and ad-
just shims from the transaxle case. (Refer to
page 7C—88.)
(2) Set the differential assembly into the convert-
er housing.
(3) Install the outer race removed in step (1) into
the SST; then set them on the differential as-
sembly.
Caution
Eliminate the gap by turning either A or B of
the selector.

7C ASSEMBLY
(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 0.15 mm (0.0059 in) to the measured
clearance, and select the shim(s) closest in
valve to that measurement.

Caution
a) Measure the clearance around the entire cir-
cumference, and select shims equivalent to
the maximum clearance.
b)The maximum allowable number of shims
is 3.
(14) Remove the transaxle case and selector.
(15) Install the required shim(s) and tap the bear-
ing race into the side bearing housing.

Procedure
1. Install the governor assembly.
(1) Mount the governor along with a new gasket
onto the transaxle case so that the sleeve
projection is aligned with the alignment mark
on the transaxle case.
(2) Install the governor cover along with a new
gasket.
Tightening torque:
8—11 N-m (80—110 cm-kg, 69—95 in-lb)
2. Apply a thin coat of silicone sealant to the contact
surfaces of the converter housing and transaxle
case.
3. Install the transaxle case onto the converter
housing.
Tightening torque:
29—46 N-m (3.0—4.7 m-kg, 22—34 ft-lb)
4. Install the SST into the differential side gear.
Caution
Failure to install the SST may allow the
differential side gears to become misaligned.

7C INSTALLATION
(3) Install and tighten the reamer bolts, then install
and tighten the standard bolts.
Tightening torque:
Reamer bolts 7—10 N-m
(70—100 cm-kg, 61—87 in-lb)
Standard bolts 42—62 N m
(4.3—6.3 m-kg, 31—46 ft-lb)
(4) Pull the front hub outward to connect the
driveshaft to the joint shaft.
(5) Push the joint from the differential side to se-
curely connect the driveshaft to the joint shaft.
Caution
a) Do not damage the oil seal.
b) After installation, pull the front hub outward
to verify that the driveshaft is secured.
Install the left driveshaft as follows:
(1) Pull the front hub outward to insert the
driveshaft into the transaxle.
(2) Push the joint from the differential side to con-
nect the driveshaft to the differential side gear.
Caution
a) Do not damage the oil seal.
b) After installation, pull the front hub outward
to verify that the driveshaft is secured.
Install the lower arm ball joints to the knuckles and
tighten the bolts and nuts.
Tightening torque:
36—54 N-m (3.7—5.5 m-kg, 27—40 ft-lb)
Install the under cover.
Install the stabilizer bar control link as follows:
(1) Install the stabilizer bar control link.
(2) Adjust length A to 20.1 mm (0.79 in).
(3) Tighten bolt B to the specified torque.
Tightening torque:
16—23 N-m (1.6—2.3 m-kg, 12—17 ft-lb)
Install the tie-rod ends and cotter pins.
Tightening torque:
29—44 N-m (3.0—4.5 m-kg, 22—33 ft-lb)
