did you ever upload a recording of the sound?

if you can't do the tape test you can unbolt the sway bar links to confirm they aren't the problem. also; sway bar is tied to the 'frame' with 4 stretched to yield bolts; most often people don't re-install those properly and if they get loose they make a TERRIBLE RACKET; (i know from experience); that is very much a clunking vs. tapping noise.

Silly me i took off the stiffening plate and just hand-tightned the bolts to make a quick run to the car parts store, holy hell it was like somebody hitting the bottom of the car with a 3# hammer every little bump in the road!
