You won't be able to repair every type of stairway with these methods, but you will be able to repair most of the conventionally framed stairways that used individual stringers, treads and risers to build a set of stairs. Keep in mind that most noisy stairs are the direct result of something rubbing up against something else like a nail, step or part of the framing.
