What Causes the Rear-End Noise at Low Speed in the New Buick Regal?
1 Answers
There are many possible causes for "abnormal noises" from the car chassis: 1. Loose or deformed chassis components causing noise. 2. Noise originating from tire tread patterns. 3. Noise coming from internal components of the engine or transmission in the chassis area. 4. Noise from various connecting parts of the drivetrain. 5. Noise from front or rear wheel bearings. 6. Noise caused by human error during maintenance, installation, replacement, or repair, such as improperly tightened screws, component interference, incorrect positioning, or reverse installation due to negligence or carelessness. This can be very dangerous. 7. Noise from critical safety components: for example, in the braking system, it could be due to worn brake pads reaching their limit and grinding directly against the disc; or chassis noise caused by lack of oil in the power steering system.
