WARNING: This page does not describe the selected car, but rather 58 other vehicles, including the 2003 Saturn Vue, 2003 Saturn L300, 2003 Saturn Ion 3, 2003 Saturn Ion 2, and 2003 Saturn Ion 1. However, it is still accessible from the selected car via links, so may be relevant.
A "whirring or squealing" type noise will increase or decrease relative to the vehicle speed and may be caused by a worn bearing within the driveline assembly. A minor "whirring" type noise should be considered normal. Replace the bearings as required.
