Rattle Noise
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 loose driveshaft hub clamp bolt may create a "rattle" type noise mainly at idle in the flywheel area of the transmission housing (automatic transmission applications only). Tighten driveshaft hub clamp bolt to appropriate specification.
