i put mine on jack stands by the frame under the rear doors. i then took the shocks off, undone the e brake cable at the frame side (on the drivers side) i then disconnected the driveshaft. i then took the passenger side leaf pack off and rolled the rear end straight with the truck *passenger side forward and the drivers side to the rear* i then dropped the drivers side leaf spring from the shackles and put the rear end over the leaf springs. i then put the passenger side leaf back on and installed my flip kits. i found it was easier with a transmission jack to hold the rearend.
