Installed MDU coilovers, all was ok. Next day there was a noticeable knocking coming from bumps at slower speeds so I pulled the seats out and checked the top bolts, same with the tire and the 2 19mm bolts at the bottom of the strut (which took a 1/6 turn to tighten). Also checked sway bar and wheel for movement. Everything is done up tight with no play at all yet knocking persists.
Only thing i can think of i left the hats off and the noise could just be normal yet more noticeable now. Also dampers were set rock hard initially and I went for a bumpy ride perhaps damaging something.
Is there anything obvious I should look for?
