The mention of the "temperature swing" is definitely interesting. I had the repair done by the dealership just as we were heading into cold weather here in NY. I thought the problem went away because I hadn't heard it. But this past weekend, we had very unseasonably warm weather in the mid 60s and the creak returned just as bad as it was prior to getting the repair. This is extremely disappointing. I'm with Bigg Tree above. The noise makes the car impossible to drive without annoyance.
