3E-2 REAR SUSPENSION
GENERAL DESCRIPTION
Rear suspension is 5 link type of rigid axle which consists of coil springs, rear axle, shock absorbers, upper rods,
lower rods and lateral rod.
The lower rod and upper rod are connected with the axle and body by using bushes so that axle moves up and
down with bushes as their supporting points.
The shock absorber is installed between the body and axle to absorb up-and-down movement of the vehicle body.

INNER OIL SEAL CHECK

When brake drum has been removed, check inside of brake drum
for gear oil leakage.

Also, check backside of brake back plate for oil leakage.
If oil leakage is found, replace defective oil seal.

Whenever it is possible to check oil seal during disassembly,
check its lip for wear.
If oil leakage or worn lip is found, replace defective oil seal.
WHEEL DISC, NUT & BEARING CHECK

Inspect each wheel disc for dents, distortion and cracks. A disc
in badly damaged condition must be replaced.

Check wheel hub nuts for tightness and retighten to specification
as necessary.
Tightening Torque
(a): 100 N
.m (10.0 kg-m, 72.5 lb-ft)

Check wheel bearings for wear. When measuring thrust play, ap-
ply a dial gauge to axle shaft center after removing wheel center
cap from wheel.
Thrust play limit
Rear0.8 mm (0.03 in.)
When measurement exceeds limit, replace bearing.

By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If it is defective, replace bearing.
