If anyone is still interested.. I finally silenced my sway bar again this week. Kind of cross-posted from my autox log:

So lets exhaust the subject. With any aftermarket front sway bar there are a number of potential causes of noise and interference. I've got to think I've encountered them all:
- Front sway bars have little clearance (Whiteline does, at least) and must be pretty precisely centered to avoid interference. Adjust collars by mounts to fix.
- The retention collars can/will interfere with the sway bar mounts, from my post above. Grind them down so they'll clear. More:

- End link studs can interfere with control arm and inner fender well. Adjust endlink length and add spacers to studs to fix. More:

- Preload and binding issues. Adjust endlink length with car on a level surface and suspension settled to fix.
- Jamb nuts backed off allowing endlink to work itself loose and adjust itself. Threadlocker on jamb nuts to fix.
- Maybe not important here, I just noticed Friday night that my race tires have been rubbing on both the sway bar and interior of the fender well. Part of my project for the week was to add camber bolts, lengthened wheel studs and 5mm spacers, so hopefully this is fixed. I'll check it out tonight. The race tires are 245/40-17 Hankook Z214s on stock wheels.

- Finally.. a loose fscking nut on one of the endlinks. This is what I chased all week. The 5th time under the car, with modified stock endlinks in hand and ready to install, I found out the driver's side endlink was just loose at the sway bar. Are you kidding me?
Between all these problems I probably have a good 48 hours of poking and testing invested. But now my car is quiet.
