If I remember correctly you have access to a lift at a family members house. I would suggest putting the car on a rack and checking the front and rear suspension for loose components. If you have a tierod or other joint that has play in it that could cause the clunk. I like to load the suspension knuckles so the suspension isn’t sagged so you can better check everything. Just my .02 before you start spending money.
The lift is mine. At my house.
The car needs those parts anyway…it’s got 120kmi and they have never been changed. But I will be doing what everyone has suggested when I get it on the lift as well.
Update:
Looks like you guys called it…sway bar/stabilized end links…I’m shocked they went at 20kmi (I installed new ones when I installed the coilovers) after the factory ones lasted 101kmi (or at least 70k, since I got the car with 30kmi). Oh well…these have a 3 year warranty so I basically got new ones from Advanced Auto for free.
Noise is gone.
