What Causes the Abnormal Noise When Accelerating During Parallel Parking in a Teana?
2 Answers
Abnormal noise when accelerating during parallel parking in a Teana may be caused by faults in the fuel pump, release bearing, intake pipe leakage, brake caliper, and other areas. Fuel Pump or Release Bearing Damage: The abnormal noise when accelerating could be from the fuel pump or related components. Alternatively, it might be due to damage to the clutch release bearing. Intake Pipe Leakage: It is necessary to check if there is any leakage in the engine's intake pipe, whether the air filter is properly installed, identify the source of the noise, and check if the engine belt is aged, loose, or slipping. Directional Diagnosis: Determine where the noise is coming from. If it's on the right side of the engine, it's usually the generator belt; on the left side, it might be an issue with the throttle body. For the front wheel brake pads, the main cause is often the brake caliper, with a small possibility of partial seizure. It could also be due to damage caused when pressing the brake caliper piston back during installation, leading to a certain degree of seizure.
When there's abnormal noise while pressing the accelerator during parallel parking, I suspect it might be related to the chassis steering system. When turning the steering wheel, the wear on the tie rod or ball joint connections can cause friction sounds at low speeds. The friction between the tire tread and the curb can also produce some noise, especially if the steering is turned too sharply, which can intensify the abnormal sound. The moment you press the accelerator, the engine load increases, transmitting vibrations to the suspension. If the chassis or bushings are worn out, it's more likely to produce noise. My car used to make similar noises, and during repairs, it was found that the rear axle bushings were loose. Regular inspection of chassis components and tire wear is crucial; otherwise, abnormal noises could develop into more serious steering failures, affecting driving safety. I suggest you avoid sharp turns when parking next time and try turning slowly a few times to see if the noise changes.
