Annoying squeak/rattle/clunk sound with gas pedal, Ideas?

Over the last few weeks, I've noticed a really annoying squeaking or rattling noise coming from what seems to be the front drivers side wheel area. I do a ton of city driving in Washington, DC where the roads are terrible and rampant with potholes and road debris so at first I thought maybe it was just normal road noise or something similar.

I've started to be able to pinpoint more specifically when it happens and how. It happens almost exclusively at lower speeds (10-35mph) and more particularly when I either tap the accelerator very softly or release of the accelerator slowly. It almost never occurs when my foot is not on the accelerator or if I am traveling at highway speeds (50+).

I've published two videos to show this issue, and you can also tell from the MPG reader on the dash when I disengage the accelerator as the MPGs shoot upwards. Last week I was at the dealer for an oil change and asked them to take a look. I don't think they did a very good job attempting to diagnose it because they said it was more of a knocking sound that a squeak or rattle, and wanted me to replace the front struts ($1200). I'm not certain that is the cause.

Anyway the videos:

First Video

You can clearly hear it at the 2 second mark, 11 second mark, and 15 second mark. Each time is when I release off the accelerator briefly.

Second Video

You can hear it at the 1 second mark, 7 second mark, and 11 second mark.

Anyone else experience this issue? Most of my research I've found is related to brake related noises which does not appear to be the case here as this never happens when I use the brakes.

Any input would be appreciated.
Thanks
