What Causes the Abnormal Noise When Accelerating in a Levin?
4 Answers
The reasons for abnormal noise when accelerating in a Levin are as follows: 1. Possible engine noise, usually a metallic screeching or wind-like whistling sound. 2. Possible transmission noise, if there is abnormal noise inside the transmission while driving, which disappears when the clutch or accelerator is pressed. 3. There may be a whistling-like sound when shifting gears or abnormal noise from the doors. Below are the solutions for abnormal noise when accelerating in a Levin: 1. Engine-related solution: Engine noise indicates a change in the technical state of a certain engine mechanism, mainly caused by excessive wear of some parts or improper assembly and adjustment. Some noises may even predict potential catastrophic engine damage. Therefore, when engine noise occurs, it should be repaired promptly to prevent the fault from escalating. 2. Transmission-related solution: During analysis and judgment, pay attention to whether the noise is related to specific speeds, certain gears (if a particular gear is noisy, it is definitely related to components affecting that gear's transmission), or specific actions. 3. Door-related solution: Door noise is mainly caused by lack of lubrication. Special door accessory lubricating grease should be used, as engine oil or ordinary grease is not suitable—it may freeze in winter, and harmful odors can affect health.
Seeing you mention the Levin has throttle noise, I think it’s quite common—likely an issue with the belt system. I’ve experienced something similar while driving, hearing squeaking or clicking sounds during acceleration. This is usually due to insufficient belt tension or an aging tensioner pulley. Rubber materials deform and loosen over time, causing noise when rubbing. It could also be wear in suspension components like control arm ball joints, where throttle-induced vibrations amplify the sound. If the noise only appears when going uphill or turning, it’s more likely related to worn driveshaft universal joints. Though minor, ignoring such noises can accelerate damage to other parts—like a snapped engine belt leading to a breakdown, which is dangerous. I recommend visiting a professional repair shop soon for inspection. During maintenance, don’t forget to replace belts and fasteners to prevent many issues. You can also try locating the noise source yourself by listening near the engine bay.
I've been driving my Levin for several years and recently noticed a rattling noise when accelerating. I took it to the shop for inspection, and the technician said it could be due to excessive gear clearance in the drive shaft or insufficient oil in the differential causing friction noise. This issue is more common in high-mileage vehicles, where inadequate lubrication leads to rough metal-to-metal contact, making the noise noticeable when accelerating. Another possible cause is an air leak in the engine's intake system or a clogged air filter, which can create a whistling sound due to restricted airflow. Ignoring such noises is not only annoying but could also lead to more severe damage, such as transmission component failure, which is harder to repair. Regular maintenance, like changing fluids and inspecting suspension connection points, can significantly reduce the chances of such noises. If the noise becomes frequent, it's best to consult a technician for a professional diagnosis with specialized tools.
The throttle noise in the Leiling is mostly caused by aging mechanical components, such as loose belts, failed tensioners, or cracked suspension bushings. Poor lubrication is also a key factor; oil thinning or insufficient oil over time increases component friction, making the noise louder under acceleration stress. In some cases, a whooshing sound from exhaust system leaks due to high-temperature corrosion may be the culprit. Incorrect readings from ECU sensors can also lead to abnormal engine response sounds. Early intervention can prevent chain failures; it's recommended to first inspect the belt system and fluid conditions to nip minor issues in the bud.
