My 2003 Explorer XLT makes a whoop sound. The first time I heard it I thought it was a siren. It only lasts a few seconds and then it stops. It sounds like it is coming from the rear end. My husband says I need to record it I don't know how to describe it other than a whooop siren like sound. Has anyone else had this problem? It seems to only occur after driving at high speeds (freeway driving), and it does not happen all of the time! Any ideas?????

There is a TSB "Technical Service Bulletin" on rear wheel bearings being noisy on that model. If it is still under warranty, then get to your dealer!

TSB info...................

FORD: 2002-2005 Explorer
LINCOLN: 2003-2005 Aviator
MERCURY: 2002-2005 Mountaineer

This article supersedes TSB 05-17-10 to update the Service Procedure.

ISSUE:
Some 2002-2005 Explorer 4dr/Mountaineer and 2003-2005 Aviator vehicles may exhibit a noise from the rear wheel hub bearings. Previous service procedures required service replacement of the wheel hub bearing assembly, base part (1109). This new service procedure allows replacement at a lower service level of the wheel bearing, base part (1215) to repair the noise condition.

ACTION:
Replace the rear hub bearing and wheel bearing retainer ring
