There isnt much to take apart up front except for disconnecting the sway bar, 3 top plate bolts, the lower shock bolt and then for putting it back you would have to undo the four bolts on the bottom of the hum assembly. I havent put in add-a-leafs though, I believe that is just unbolting the pack after removing the rear leaf spring bolt and then putting the new leaf in. You should ask them how much they are thinking they have to "take apart".
