    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.
