Ensure tires are properly inflated prior to checking or adjusting caster angles.

Fig. 2 Caster adjustment. Prelude & 1986-88 Accord:

1. Raise front of vehicle and position turning radius gauges under front wheels, then lower vehicle.
2. Remove spindle nut and install suitable caster gauge and adapter, Fig. 1.
3. Apply front brakes and turn wheels 20° inward.
4. Position caster gauge at 0°, then return wheels to straight-ahead position and note gauge reading. If caster angle is not within specifications, inspect suspension components for damage and repair as necessary, then recheck caster.
5. If caster adjustment is necessary, loosen radius rod adjuster locknut and self-locking nut on end of radius rod, Fig. 2.
6. Turn radius rod adjuster in to increase caster or out to decrease caster as necessary. One complete revolution of the adjuster moves radius rod .049 inch and changes caster 2/15°.
7. Tighten radius rod adjuster locknut and self-locking nut, then recheck caster angle.
