Once your shackle or shackles have inverted, driving on them is harsh and jarring. It’s also a great way to bend a spring. Stop quickly and grab a long prybar. Shove the prybar between the shackle and frame (or bumper in our case) and try to leverage the shackle back into the position. If you can’t get the shackles to return to vertical, you may have to jack the Jeep up a little to get the weight off the springs and shackles. Either way, keep your head and body parts clear of the prybar, as springs store lots of potential energy and you don’t want to get whacked if it suddenly releases.
