2. Remove the wheels.

3. Loosen but DO NOT REMOVE all 8 control arm bolts (fig. 1).

4. Loosen but DO NOT REMOVE the Track Bar hardware (fig. 2).

10. Install front spring spacers with molded posts pointing upward. Place bumpstop spacer inside spring and install both together (be sure counter-bored hole is on top). With AEV logo facing outward, make sure bot posts on the spring spacer engage the holes in the frame. Make sure spring is properly clocked into the lower spring mount and raise axle slightly to hold the assembly in place (fig. 17).
