14 hours to do the lift? did i miss something, i just installed mine. 5100/eibach spring combo. took me roughly 3 hours to do front and rear.
front remove wheel, remove lower shock bolt, upper 3 bolts. sway bar end link, remove 4 lower balljoint bolts. secure coilover assembly with upper bolts finger tight. pry UCA downwards and line up the lower shock bolt. then use a jack from below the LCA and line it back up. torque bolt's and release jack. re-connect sway bar end link.
rear took even less time. jack truck up, remove bolt's from diff housing for hard lines/mount for brake line tree so it can "bend up some" and allow more diff sag. brush dirt out of u-bolt threads. little heat, penetrating lube. breaker bar and remove by hand. compress leaf springs together with c-clamp at front and back of differential. remove nut off centering pin. drop differential down, slip in your AAL. gently raise differential into place, leaf's will remain centered. may take a bit of tension to push it through. then reverse steps.
that's how i did mine. all on the ground with hand tools, first time working with a leaf spring in my life, i had tinkered with the front a bit before though.
