I don't understand why I cannot convey that before this vehicle, or "abortion" as you so eloquently put, was parked for a long duration there were no problems in the steering; which means that regardless of what angles the track bar, tie rod bar, alignment geometry specs, or any equipment being used, actually WORKED. I don't know what happened during that 8+ month or so time period when it wasn't driven normally that could have caused this severe of damage to anything, but something did and I have been chasing it since. While it was in between build stages I took it for a few short cruses, but I wasn't bouncing it off rocks or jumping curbs, just some "spirited" driving.
Over the last 2-3 years now I have replaced items I could think of as possible culprits with O.E. or substantially higher quality in an attempt to resolve this problem. I am now at the point where I believe the only thing left that it could be is the slightly bent/bowed frame mounts for the control arms.
