What Causes the Rear Wheel Noise?
2 Answers
Here are the specific reasons for rear wheel noise in cars: 1. Foreign object accumulation: Excessive accumulation of debris on the fender or sound insulation pad. When the car turns, the tire interferes with these objects, producing abnormal noises. Cleaning the fender usually eliminates the noise. 2. Screw detachment: Loose or detached screws on the fender or sound insulation pad cause these parts to lift. During turns, the front wheel may interfere with them, creating friction noises. It's necessary to inspect the fastening condition of fenders and sound insulation pads, and address any looseness or lifting issues. 3. Unauthorized modifications: Using non-standard size tires through unauthorized modifications. For example, installing wider tires or increasing tire diameter may cause interference with the car body during turns, producing noises. This poses significant safety risks, and the original size tires should be reinstalled.
I've encountered the issue of abnormal noises from the rear wheels several times. The most common cause is problems with the rear wheel bearings, such as wear or seizing, which results in a humming sound while driving, especially noticeable at high speeds. Another major issue is the braking system, for instance, worn-out brake pads or stuck calipers, which produce a sharp squealing noise that's quite unpleasant. Suspension components shouldn't be overlooked either; loose or damaged bushings in the stabilizer links or control arms can cause rattling sounds when going over speed bumps or uneven roads. Tires also play a role—if they're unevenly worn or have a nail puncture, they can emit a rhythmic noise while rolling. I believe that once you hear any abnormal noise, it's essential to get it checked as soon as possible and not delay. If a bearing fails completely, not only is the repair expensive, but it's also dangerous. Always stay alert while driving—safety comes first.
