Ive had this happen on 2 NAs. Everything was tight, checked a few times, and both cars were fixed by replacing the control arm bushings. They were worn enough to slide closer to the subframe, and under braking only the rubber would smoosh until the arm contacted the subframe making a click noise. Drove me insane for a few months on my 90.

Alright, put her up in the air, started checking bolts. Subframe bolts, good.
I wasnt aware that camber is adjusted by the lca via eccentric. On the 944 is at the bottom of the strut, so the clunk has a different behavior.
Point is, one of the four camber bolts on the front was loose. Clunk gone.
Thanks to those of you who threw out ideas! Sorry for doubting any, the result of that issue on the 944 is the knuckle not being pinched, leaving slop on the direction of camber. This was all snug, except under hard maneuver.
Relief!

had a very similar clunk. my car has new poly bushings all around and new eccentric bolts. everything was tight. i was leaning towards the hub bearing. i got in there with a crow bar and noticed the sway bar was the culprit. someone had used a slightly smaller than the hole diameter bolt, and the bar would ever so slightly shift and clunk at very random times (hard braking, lifting a wheel, etc) just check every connection at the front suspension, its not too hard.
