Yes, I installed new OME UCAs and aligned within specs.
The marks are on the front of the struts--I'll try to get photos at some point. I have no idea if this is the cause or result of the noise. I'm just speculating. It could have simply happened during install. It's pretty tight in there, and these are obviously much thicker than the ones that came off of there.
EKDSS should still be functional. We had numerous conversations about it, and they were familiar with it due to work on prior Toyotas/Lexus with KDSS. One of the main reasons I went with with the OME setup was because I knew it was compatible with the KDSS system.
Tires and wheels are still stock Overtrail and Toyo ATIIIs.
The only time I've noticed it was on very severe downhill slopes while at the same time performing a sharp turn--think going downhill on steep switchbacks. Otherwise, I haven't noticed it. It was only under very specific conditions, and I thought I felt a bit of feedback in the steering wheel, which is what led me to believe that the steering linkage could have been physically impacting something.
