LEAF SPRING

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.

REMOVAL

1. Remove the wheel and tire from the vehicle using power tool. Refer to 

WT-48, "Adjustment"

.

2. Support the rear final drive assembly with a suitable jack to relieve the tension from the rear leaf spring.

• The axle weight should be supported, but there should be no compression in the rear leaf spring.

3. Remove the four rear spring clip U-bolt nuts using power tool,

then remove the rear spring pad and bumper.

4. Remove the rear spring shackle and bushings using power tool.

5. Remove the rear leaf spring front nut and bolt using power tool.
6. Remove the rear leaf spring.

INSPECTION AFTER REMOVAL

• Check the rear leaf spring for any cracks or damage. Replace the rear leaf spring if necessary.

• Check 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.

• Check 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 bumper and rear spring pad, then finger-tighten nuts under the axle case.

5. Tighten the rear spring clip U-bolt nuts diagonally and evenly to

specification.

• Tighten the rear spring clip U-bolt nuts so 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), as shown.

6. Remove the jack supporting the rear final drive assembly and

bounce the rear of the vehicle to stabilize the suspension.

7. Tighten the rear spring shackle nuts, rear leaf spring front nut, and shock absorber nuts to specification.

• When installing the components with rubber bushings, the final nut tightening must be carried out under

unladen* conditions with the tires on level ground.

* (Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated posi-

tions.)
