*Thunk* and rattle in left front suspension

14 BRZ, 8K miles

Tein Monosport 8K/9K
factory sway bar
whiteline endlinks FR/RR
~2' front camber
17x9 RPF1 w/ 245/45/17
hotchkis front upper strut bar

Ever since alignment, which just happened to coincide with endlink installation, I get a massive *THUNK* out of the drivers' side front when going over uneven road. It seems to happen when unloading suspension, but I can't be sure.

No signs of contact/abrasion anywhere in the suspension. Sway bar and endlink appears to clear control-arm and shock body with room to spare. Re-torqued strut tower bolts, endlinks, spring perches, and verified that spring is slightly pre-loaded.
I've had it up on alignment rack 3x and up on 4 stands in my garage probably 4-5x as well.. with wheels both loaded and unloaded.

When I encounter lesser undulation on that side of the car, the sound that corner makes I can only liken to a spring rattling around a shock body.

At this point, I'm thinking it's a defective strut (<3K miles on them), but there are no signs of oil anywhere either. Losing my mind.

Has anyone here experienced something similar?

Thanks
