What to Do When Abnormal Noises Occur While Driving?
2 Answers
When abnormal noises occur while driving, you should promptly pull over and inspect the vehicle. The following are the main causes: 1. Body noises: Check items inside the car to rule out noises caused by loose objects. If the noise is due to friction around the doors or windows, applying adhesive strips to the doors and windows or placing rubber padding in the friction areas can help reduce or eliminate the noise. 2. Engine noises: These are mainly caused by excessive wear of parts or improper assembly and adjustment. Some noises may indicate potential serious engine damage, so the vehicle should be sent to a repair shop promptly to prevent further damage. 3. Brake noises: The noise increases when lightly applying the brakes. Possible causes include excessively thin brake pads, uneven wear between the brake disc and pads, or faults in the brake calipers, master cylinder, or wheel cylinders. These typically manifest as sharp, continuous sounds. 4. Tire noises: First, check if the tire bolts are tight to rule out this symptom. If the wheel hub bolts are severely loose, the wheel may wobble while driving, producing noticeable clicking sounds at low speeds.
When there's a strange noise while driving, I usually slow down and pull over to a safe spot first. Don't rush to roll down the window to listen, to avoid accidents. Then try to identify the type of sound: if it's a squeaking noise, it might be worn brake pads; if it's a clicking or clunking sound, it could be loose suspension or connecting rods. If there's a small stone stuck in the tire, it can also make noise—just pick it out. Unusual sounds from the engine area? It might be a loose belt or the fan hitting something. I often use my phone to record the sound and play it for the mechanic at the repair shop, which makes it easier to pinpoint the issue. If you have some mechanical knowledge, you can use a wrench to tighten key screws, but don't force it—after all, tampering with electrical circuits or internal components yourself carries risks. During regular maintenance, check the chassis and wheel hubs more often to prevent small issues from becoming big ones. Remember, driving safety always comes first.
