Check to ensure tires are properly inflated, balanced and not out-of-round. Barring any problems w/ that I would suspect the driveaxles/CV joints. These have a tendency to create vibrations (when they are going bad), both during acceleration/ deceleration and at highway speeds.
I would also suspect a bearing but, you said they have been changed so, I suspect the driveaxles. Not quite sure what you mean by "spindle."
