The "torque wrench" idea is a great one that I have not thought about before. However, I took the stem and the seat post apart, cleaned them and used my favorite tool of all time….WD 40. The creak is gone. It was in the seat post as far as I can tell. I ride quite often, and wash the bike regularly. The seat post had a lot of crud mixed with grease. All cleaned off; all creaks gone! Thanks for the roadmaps.
