The following information is derived from the FAA's Service Difficulty Reports and Aviation Maintenance Alerts. While retracting and extending the landing gear for adjustment of a drooping inboard main wheel door, abnormal noise and vibration (was noted at mid-cycle). Further investigation found the r/h main landing gear retract rod assembly chafing on the wheel well's fuel crossfeed tubes (p/ns 002-920000-49 and 002-920000-51).
