Front end clunk, has anyone heard a similar noise

[86franklin]

Guaranteed to make the noise when accelerating from a dead stop, going over speed bumps.

I know my control arms are tired but all seem tight no play in the ball joints or anything like that. The forward lower arms were replaced last fall. Axle hub bolts are tight and axle nuts are tight. Subframe mount bolts are tight. I'm not asking for internet troubleshooting. Just wondering if anyone has heard a similar noise and found the cause and will save me some head scratching.

Here's a video. You can hear it with headphones for sure. Every time I take off from a stop light. The first one is at roughly 0:30.

sway bar bushings make sure the bolts on the u straps are tight.

Didn't think to check those nor did I think they could make that kind of a clunk. Thanks for the suggestion.

How about your steering rack bolts? 10mm 12pt bolts, one located under the battery tray and the other around the brake booster area.

There's a 3rd that's accessed from under the car, but if the top two are tight, it wouldn't/shouldn't clunk either way.

I'll check them after work today. I haven't touched them though so I'm am hoping they are tight.

It's not uncommon for them to loosen overtime on C5s, especially the passenger side bolt.

Well the sway links and steering rack is tight. But I grabbed the axle closer to the trans and there is some slop it seems in the bearing. Which I'm assuming isn't supposed to be there.

I'll need to check too now it seems. I get an occasional clunk as well, not very consistent. Hoping its an easy fix.
