What Causes Abnormal Noise from the Left Side While Driving?
2 Answers
Reasons for abnormal noise from the left side while driving: foreign objects in the tire, aging or loosening of engine mounts, or inaccurate vehicle wheel alignment. Below are the details: Foreign Objects in the Tire: During driving, if you hear a tapping sound when opening the window, the first thing to check is whether there are foreign objects on the tire tread. The uneven surface of the tire tread can easily trap foreign objects such as stones or nails. During daily use, after turning off the engine and exiting the vehicle, inspect the tires. If there are foreign objects like stones, clean them promptly. Aging or Loosening of Engine Mounts: Engine mounts are rubber blocks placed between the engine and the frame. Their function is to reduce vibration and cushion the engine's operation while securing the engine in place. If these mounts age or loosen, the engine may start to shake, and in severe cases, produce a "tapping" noise. In such cases, simply replacing the engine mounts will resolve the issue. Inaccurate Vehicle Wheel Alignment: Inaccurate wheel alignment can cause significant tire wear during long-distance driving, leading to uneven tire wear and abnormal noise. If this is the case, it is necessary to visit a 4S shop or repair shop for inspection and repair.
I've been driving for over a decade and often encounter left-side noise issues. The most common cause is worn suspension components like shock absorbers or control arm ball joints, which make loud noises on bumpy roads. Last time my car had this issue, it creaked when going over bumps, and it turned out to be a loose left front wheel bearing. Tire problems are also common—uneven tire pressure or unbalanced wheels can cause a humming noise at high speeds. Loose tie rods in the steering system can produce noticeable clunking when turning. Loose chassis bolts or worn brake calipers can also cause friction-related noises. I recommend doing a simple self-check first: stop the car, shake the wheels to see if they wobble, or listen for the exact location of the noise. But it's best not to delay—take it to a professional repair shop for a thorough inspection. Regular maintenance and part replacements can prevent this issue. With my experience, I can handle similar problems quickly without delaying your drive.
