Check out the TSB below. This might be the noise that you can hear - if it comes from the front area: Drivetrain - Front Drive Axle Squeal/Squeak Bulletin No.: 03-04-19-002B Date: April 04, 2005 Subject: Squeak, Squeal or Whistle Noise from Front Axle (Replace Intermediate Axle Seal and/or Differential Carrier Seal) Models: 2004-2005 Buick Rainier 2002-2005 Chevrolet TrailBlazer 4WD 2002-2005 GMC Envoy 4WD 2002-2004 Oldsmobile Bravada AWD Supercede: This bulletin is being revised to change the Warranty Information. Please discard Corporate Bulletin Number 03-04-19-002A (Section 04 - Driveline/Axle). Condition Some customers may comment on a high pitched squeal, squeak or whistle noise in the front end of the vehicle. This noise usually occurs once per wheel revolution. This may be more common in cold weather below 5°C (40°F). The noise may be coming from the right front axle intermediate shaft housing outboard seal or the left outer differential carrier seal. For testing purposes, spraying a lubricant on the seal should temporarily reduce the noise. This noise should not be mistaken for a wheel bearing issue. Cause A lack of lubrication in the seal may cause this condition. Correction Replace the right front axle intermediate shaft housing outboard seal or the left outer differential carrier seal using the following procedure and part number listed below. I hope this will help. Zee
