Knocking noise at low speed
Hi guys,
I drove into DC for work and during heavy traffic (crawling speed) the car was making knocking noise and I could feel the knocking gently through the steering wheel and the bottom of my feet.
The knocking happened when I am crawling at 5-10mph, right when I let go of the accelerator. When I apply consistent pressure on accelerator to accelerate out of the crawl or consistent pressure on the brake to come to a slower speed or stop, there is no knocking.
So, to summarize, at low speed, when I let go of the accelerator, the car expectedly jolts gently, because of the letting go of the accelerator and that is when I hear a knock. Almost sounds like the knock is happening during gear engaging(?) or throttle opening/closing.
I will be taking the car to an indy MB shop sometime next week but I would like to ask here to get an idea of what this could be before.
Thanks in advance!

LOL, so it turns out it was my tow hook in the trunk, rolling around. What a coincidence that I opened the luggage compartment today to find it out of its holder and rolling back and forth.
