Had a bunch of storms and flooding the San Antonio area recently so I didn't get much of a chance to tinker on the Xploder.. I did finally get to pull 1 wheel off, though car was in driveway on a decline so didn't want to put into neutral and mess with it to much so mostly just a quick visual check.. The POS MOOG ball joints on the upper control arms look shot... again, lol. Also the pads somewhat low and rotors pretty corroded from so much time on and off sitting around in the elements undriven (until fairly recently). I think I'll just replace the upper control arms (with ball joints), again, and the front and rear pads and rotors...

Anyone who had been following this thread for the past decade + may recall the junk MOOG ball joints crapping out on me last time after I installed them and car sat a few years and the rubber boots disintegrated, lol.
Some light rain
Anyways...
Maybe the source of the sound? Also seems to be a tad brake pad drag on the rotor that may be assisting some additional noise expanded by the rotor grooves.
This time I think I'm going with the Mevotech TTX upper control arms, Power Stop CRK1861 Geomet coated rotors (blank, no fancy slots, grooves, or holes lol), and ceramic brake pads. I put those same rotors and pads (same version) on my wife's Mustang last month and they seem really nice and still look mint.
Also.. I've been busy expanding my 3d printing hobby, lol.. Picked up a Creality K2 Plus multi color printer... It's a BEAST. Now I can print some custom emblems in ASA with multi color which is pretty awesome. I also have a Silhouette cutter that can cut shapes and stuff that I think I will be able to use to cut sheets of double sided 3m tape so the plan is to 3d print an emblem and then use the cutter to cut the 3m tape for an exact fit to the back of the emblem... in theory at least, lol.
First test print with multi color...
