Can't figure this noise
 

Sorry if this is another annoying post about strange noises...
I think this has been going on for about 2 years now, when accelerating its all smooth, but when im coasting and slowing down enough i hear a loud rattle, almost like a diesel engine, if i touch the gas it stops, or i i brake hard enough it stops. I hear it most when im pulling into a parking lot. Or coasting around the corner to my house. I took 2 short videos today, hopefully the link works.
