I made a new thread because I did not want to derail the other person’s thread. I installed a rebuilt AST 5100 using stock top hats are from a 2017 car (asked damper rebuilder to install the tops hats for me, to make sure I don’t screw it up), new spl front end links and front lower hole camber bolts. Everything else stock. The sound is most audible in the front driver’s side. The sound is a distinct thud in all small dips of the road not metal on metal hitting each other. Only in lower speed like less than 10-15miles/hr in parking area. I did double and triple checked on all nuts and bolts and all are torqued to specs and tight. Couple videos attached. Note: I have not done an alignment. Thank you in advance. Wanted to see if anybody had similar issue and got it resolved. (You may or may not need headphones to hear it. Camera is under wheel well so the sound of engine is loud too.)
