The 'death wobble' referenced comes with cars that have ELECTRONIC steering. When you disconnect it thru removal of the fuse, or batteery cable, it will cause what you're describing. That said, if it is, in fact, the death wobble you're talking about it will be a really bad wobble. Yes, Ford, Chevy and Jeep all have this issue. The fix is to power your steering while turning off everything else. Chevy fixed theirs by removing a different fuse and Jeep provided a wiring harness to fix theirs. Ford, I believe, still refuses to acknowledge the problem exists...Dennis
