I replaced the weather stripping inside the screen door which solved the rattle and whistle issue for me. The existing foam rubber was shot.
I moved my striker plate too but ended up with it back where it was. Don't forget there are two striker plates in the door.
Got D shape weather stripping from Amazon, inexpensive fix.
