Do you hear the knock when the vehicle is sitting still and in park?

Okay, that eliminates the engine. If you replaced the wheel bearings, CV joints, brakes... there really isn't anything other. Unless, the differential is having issues and not releasing the 4wd. Does it ever seem as if the 4wd is still engaged?
