Just bought a 2004 4cyl A/T Camry. Experience a "booming" noise from rear whenever the vehicle tracks across pavement separations. Noise is not typical road noise; front end significantly less noise when tracking across the pavement separations. Local dealer and zone state the noise is typical. This is my third Camry and none of the others had evidenced this type or level of noise. Anyone else experience this problem? Any dealer fixes to this annoying problem?
