This happned to me.. I got some electrical tape, wrapped it around the latch a few times, and the noise stopped. Also, if you want a more permanent solution, you can unscrew the latch, and flip it around and screw it back in.. As you drive the side of your latch gets worn, thus making it squeek. If you turn it around, you can use the fresh side of the latch, and the squeak will most likely stop. Ive never tried this method tho, just heard of it.. The tape works fine tho.
