Definitely put a few drops of Phil tenacious oil in the section of the stem where the expander bolt and washer synch up against the stem body; this is important so as the expander bolt does not become "metallically seized" with the inside (or outside if hex style bolt) upper section of the stem.

Also, be sure to coat the bar section that is clamped in stem with a thin film of grease. Grease the clamp bolt, and tighten. Remove the stem from the fork, clean both the stem and the inside of the fork, thoroughly re-grease and reassemble.

If the stem still creaks after all of the above, check the outer section of the stem clamp for a/HAIRLINE crack(s.)
