2003 protege 5 rythmic thumping

Mazda, Protege 5 2003
Hey all,

i'm having an issue with my protege the only way i can describe it is when driving at faster speeds ( like freeway) when I make a turn going either direction it sounds like a rythmic thumping with a tiny rattling noise it is pretty audible and I can feel it in the floor pan. Ive replaced both tie rod ends already because they were a bit sloppy with torn boots, replacing tie rods the thumping moved from drivers side to be only on passenger side, but im having a hard time figuring out what could possibly be making this noise and i'd like to try and fix it myself if at all possible, any suggestions or has anyone else experienced this???
