CAUTION:
When installing the components with rubber bushings, the final tightening of the nuts and bolts must
be done with the vehicle in an unladen condition (the fuel, engine coolant, and engine oil full; the
spare tire, jack, hand tools and mats in their designated positions) with the tires on the ground.
On-Vehicle Inspection and ServiceEES002JH
lCheck the rear suspension parts for any excessive play, cracks, wear, and other damage.
lShake each rear wheel to check for any excessive play as
shown.
lTighten all of the nuts and bolts to the specified torque.

INSPECTION AFTER REMOVAL
lCheck the rear leaf spring for any cracks or damage. Replace the rear leaf spring if necessary.
lCheck the rear spring shackle, rear spring clip U-bolts, bumper, and rear spring pad for excessive wear,
cracks, straightness, and damage. Replace any components if necessary.
lCheck all bushings for deformation and cracks. Replace any bushings if necessary.
INSTALLATION
1. Apply soapsuds to all of the rubber bushings.
2. Install the rear spring shackle and rear leaf spring front nut and bolt. Finger-tighten the nuts.
3. Install the rear spring clip U-bolts and bumper on top of the rear leaf spring.
4. Install the rear spring pad, and nuts under the axle case.
5. Tighten diagonally and in few steps the rear spring clip U-bolt
nuts, until the lengths of all the exposed rear spring clip U-bolt
threads under spring pad are equal in length, within a tolerance
of 3 mm (0.12 in).
Tighten nuts to specification. Refer toRSU-4, "
Components".

InspectionEES002L2
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
a. Remove tire from wheel and mount wheel on a tire balance
machine.
b. Set dial indicator as shown in the illustration.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
a. Remove tire from steel wheel and mount wheel on a tire balance
machine.
b. Set two dial indicators as shown in the illustration.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.Wheel runout (Dial indicator value):
Refer toWT-6, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)"SFA975B
Radial runout = (A+B)/2 : 0.5 mm (0.020 in)
Lateral runout = (C+D)/2 : 0.8 mm (0.031 in)
Wheel runout:
