do you use an armature or an empty to control your animation? animated rotations can be tricky sometimes without bones or a parented object.

In Object Mode select your object and press CtrlA and Apply Rotation & Scale
In Edit Mode select the vertex where you want the object to rotate, press ShiftS and select Cursor to Selected
Exit edit mode and do Transform->Origin to 3D Cursor.
