Front Suspension Clunk with my 85D

Has anyone with an 85D or 90D experienced a "clunk" while driving over "humps" (not speed bumps). My car has been with the SC for a couple days, and doing some trial and error to get to the bottom of it.

Anyone experience this and was able to resolve it?

So, I got the car back from the SC. They could not identify the sound, and told me they sent a video of it to Fremont indicating it was normal. They could reprodude the sound with a 70D and a 90D as well. Strange thing is, the 3 other Air Suspension cars that I've owned did not express the sound as they are indicating.
I guess as long as nothing is wrong, then I'm ok with it.
It's really not a big deal, as it only happens in the larger "humps"
