Mike,
Thanks, I noticed the warning in the modifiers guide also, before I made any upgrades. I suspect the primary issue is extra loading on the power steering at low (or zero) speeds, and also when hitting the limits of steering travel.

I try not to hit the limits left or right, and I also pay attention to situtations where steering torque might be extra high (e.g. trying to steer out of a deep rut at low speeds). I have not had any issues to date with about 28,000 miles, no dtc's, or other indications such as abnormal wearing on the steering components. I suspect I have not grossly overloaded the steering, or I would have seen some impact by now. I still may have issues with longevity, and am prepared for the fact it may wear out sooner.

I bet Ford considers it a good thing, that users actually read these guides, even though some of us (me!), do not always follow the guidelines.

Informally the Ford engineers I have communicated with do not expect any problem with my setup, but by their very nature, engineers are conservative, and so we get the legal warnings.
