Hotchkis bars won't stop squeaking!

[Senna-F1]

They've squeaked since they were installed, mostly the front bar. Lubed them before the install, lubed them a few times via the zerk's since the install. Torqued the brackets AND stock endlinks. Used Yellow TEFLON tape instead of lube (Blue marine grade after the install), nothing helps. Last night I torqued the endlinks with the suspension under load. Went for a drive over the humps in my neighborhood, and could barely hear them. Huge difference! These are the torture test for this sound, so it was almost perfect after doing this. By the time I had been driving for 10 min and come back, they sounded almost worse coming over those humps.

Do I need new endlinks? This squeaking has been happening since the bars were installed. I doubt my endlinks went bad at the exact moment. I don't know what else to try. I thought for sure the teflon tape would work since so many have used this method. I could undo the endlinks to see if sounds goes away, but I still wouldn't know if its the links or the swaybar bushings.
