If your talking about removing a single leaf from the pack, you have to remove the center bolt and any
clamps that hold the pack together, remove the leaf, and re-assemble the spring pack. You can do this
without removing the spring from the vehicle by jacking and blocking up at the frame high enough that
the axle will droop away from the spring when the u-bolts are removed. If you mean to remove the spring
from the vehicle, do the same thing and then remove the 2 bolts that hold the spring to the shackle and
the frame. The biggest thing to watch for is that you have ALL the pressure (weight), removed from the
spring or you can be seriously hurt.
