Steering Clunking
Just finished installing MCS coilovers, SPL rear upper arms, and SPL front tension rods. I do not have swaybar endlinks installed at the moment. Waiting after my corner balance and alignment.
After washing the car and pulling into the garage, I thought I was hearing some suspension noises. Wobbled the wheel and heard some clunking. Video is with the car off and turning the steering wheel slowly left and right. Passenger side. https://www.youtube.com/shorts/_DJasvsh6SI Now, at my last track event, I did some track side toe adjustment. I did not torque to spec as I couldn't find it, but it was tight with a 1/2in flex head ratchet. I found it last night, and torqued it to spec, still have the noise. I do not recall hearing this before, but I drive the car so infrequently, and don't really move the steering wheel with the car off. I also had a ~50mph slide on that side of the car, but did not hit any curbs or damage a wheel. My alignment was definitely messed up after the toe adjustment. But that could also be related to the Vorshlag bolt ring breaking that I tried to remove unsuccessfully. Either way, I had to turn the wheel about 15 degrees to the passenger side to keep it straight. I did some forum searching, and found that it could be steering rack related. But with new parts, it's possible it might not be. The car is currently about 1.5" higher than stock ride height. Ride height related? Coilover spring binding?

Good video have you put your hands on the moving components as you induce that clunk by moving the wheel? At times I've been able to feel the vibe or resonance in whatever part I was touching when I couldn't pin it down by ear or eye.

The tie rod was vibrating before the nut was torqued down. After I torqued it down and made sure the ball joint was in the middle position it went away for a bit but returned.
