The more I read on that page the more I can't believe you even posted this SAL!!!

After using this setup for over a year, one of my homemade discos failed while driving on the highway. Although this did not cause me to loose control or significantly change the driving behavior of my Jeep, it is never a good idea to drive at highway speeds with your swaybars disconnected. If you still plan to do this mod, I would strongly advise you to to check the hardware component on a regular basis for wear and replace them as needed.
