Road Noise

WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

Some road surfaces, such as brick or rough-surfaced concrete, cause noise which may be mistaken for tire or rear axle noise. Driving the vehicle on varying types of road surfaces such as smooth asphalt or dirt will help in determining whether road surface is the cause of the noise. Noise caused by road surface should be the same in drive or coast.
