There is a lip on the bushing around the inner diameter hole that lip faces toward the other bushing clamping to the control arm there should not be a washer in-between the bushing and the control arm. The order should be from the bottom going up, grade 8 bolt, washer, bushing lip facing up, control arm, bushing with lip facing down, washer, spacer, washer,bushing with lip up, sway bar, bushing with lip facing down, washer, and finally a nut. if you are putting in polyurethane don't forget to put on that horrible grease that acts more like glue, but stops it from squeaking which is the only down side i have found for that material when using it for suspension.
