I am hearing dull clunk coming from the floorboard area under hard acceleration it is a double clunk (up and down motion of the car)
I am guessing sway bar links or bushings, what is your thought. The struts were replaced at 55,000 miles

Does engine move up as if not attached to frame? Have you looked at sway bar mounts? Sway bar is under pressure during turns not straight acceleration. Noise from pass side? Any noise under hard braking?

The front of the engine moves up about 1/2" under hard brake torque no noise-the noise appears to come from passenger side floor board area, does not make noise under braking have not checked sway bar links or bushings
