Everything was tight, nothing had play but there was some grease or something right under the axle so that’s a bit alarming.Not sure how much help I can be, but if it's right under your feet look at anything that you had disconnected. My knee-jerk thought is to look at sway bar end links if they connect to the struts, but I know on older models they connected to the control arms. Also check your strut mounts for any play, and maybe see if the springs are able to wiggle at all when under load?
Hmm, that's strange. In the video you specified rear, my initial impression was that it was a front clunk because you mentioned it felt like it was under your feet -- I may be off base here. Did you torque your strut mounting hardware with the suspension compressed/the weight of the car on the suspension? That could also create a clunk.
Again I'm no expert when it comes to the mk7 platform, but hopefully this helps a bit.
Hmm, this almost sounds like the strut bushing/bearings. How does everything attach up there, are there two nuts or only one holding the shaft of the strut to the strut mount/bearing? Is there a 'correct' seating position for the spring, that could've been jostled when setting ride height? I don't think that'd be an issue, but maybe it's worth seeing if you can wiggle the spring at all while there's weight on it. Otherwise it could be the spring binding up, I had that happen on my FK Streetlines back when I had my mk4 -- but typing this out, I realized that if it's happening going over bumps in a straight line, that likely isn't spring bind (mine was only when turning).Update- only happens when I turn the wheel or going over bumps, definitely drivers front side. Makes me think sway bar links but those are both tight
Thank you man I really appreciate your time and response. Hoping to work on the car tmrw and check that out. Haven’t Had the time at all for the past 3 weeks. If it’s not that then I’ll most likely have my shop look at it when I get an alignment. Thanks again, will keep updated on what happensHmm, this almost sounds like the strut bushing/bearings.

If the weight of the car wasn't on the suspension when tightening the end links, that could definitely be related -- it's a common complaint in Mazda land (specifically on the Mazda3, in my experience). I built a set of ramps with 2x10s laid on one another and screwed together in order to be able to get under the front of the car with the weight on the suspension, if you've got access to a SAFE way to be under the front end/access the sway bar end links with the wheels bearing the weight of the car, I'd suggest loosening and re-tightening them to be sure.
Oh, and are these new end links or are you reusing? I'd say try re-tightening the end links before spending money on hardware that may not be necessary, either way be safe and keep us updated on what you find.
