Precautions
lWhen installing rubber parts, final tightening must be
carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire,
jack, hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake
tubes.
lAfter installing removed suspension parts, check wheel
alignment and adjust if necessary.
lAlways torque brake lines when installing.

bushing]
Make sure that front bushing is properly installed.
INSTALLATION
1. Apply soapsuds to rubber bushing.
2. Install spring shackle and front pin, and finger tighten the
nuts.
3. Install spring pad and nuts under leaf spring or axle case.
4. Tighten U-bolt mounting nuts diagonally.
Tighten U-bolts so that the lengths of all U-bolts under
spring pad are the same.
5. Install shock absorber, and finger tighten the nuts.
6. Remove stands and bounce the vehicle to stabilize suspen-
sion. (Unladen)
7. Tighten spring shackle nuts, front pin nuts and shock
absorber nuts.
