Last year I replaced all suspension components, everything, along with brakes and wheel hubs, and numerous other things I found along the way that are unrelated. After alignments kept letting me down, I bought the Suncore Air Suspension replacement kit made for my car. I inspected them side by side with the removed oem air struts before installing and everything looked identical. Seems like a nice setup.
However, on my first test drive I heard this light knock and rattle sound coming from the front while going over the slightest road imperfections yet not making noticeable sound over larger imperfections or reflective road markers. It’s subtle imperfections ONLY that make the sound, but even then it’s vague enough I can’t identify where it’s coming from or envision it. I have checked everything over and over daily since last Wednesday, to the point that I removed the front trunk interior and panels entirely until I get this figured out. Torqued everything (and broke one of the Suncore strut studs in process).
I bought another set of sway bar end links since everyone said that was likely the issue even without the links giving signs of wear. Another miss.
I tediously went through the under hood upper and lower area with foam tape and Velcro zip ties to fasten loose large cable plugs, AC compressor, on and on. I simply cannot get results.
My son has a GoPro with a wired mic and I tried clipping the mic to sway bar, bar end links, upper strut mount from underneath, upper control arm, air compressor mount r/L. It was very time consuming, but a waste of time. It sucks at picking up the sound. No matter where I placed the mic it always sounded equally faint.
For good measure I swapped out different wheel spacers and lug nuts. Tried with no wheel spacers.
Any ideas? Is there some internal air coil problem I’m not considering?
