The truss rod on my Squier Tele Deluxe creaks when I tune the G string or bend the G string. The guitar is 10 years old or so and just recently started doing this. It adjusts fine. Do I need to be concerned, and can I do anything about the noise?
Never heard of a truss rod creaking because of tuning or bending.
The nut slot, especially the G sting slot is a common cause of pinging, and creaking and it’s worse on a wound G string.
Try some graphite ( pencil lead ) in the slots and see if it improves, if it does, there’s your answer.
