CAUTION: Before tightening any suspension bushing fasteners, the suspension must be at the bushing fastener tightening position. Use a suitable jack to raise the suspension until the distance between the center of the hub and the lip of the fender is equal to 395 mm (15.55 in). This will prevent incorrect clamp load and bushing damage.
