Knock knock sound on takeoff/slowdown, non-engine issue

Hi all,

On my '85 300D, I've noticed a sound coming from within the floorboard that sounds like someone knocking on a door. It's inconsistent, and usually only happens at lower speeds when I start accelerating, then sometimes when I slow down. I've done some research and some have said it's suspension related. Any thoughts here?
