What Causes the Noise from the Rear Wheel Position After Parking?
2 Answers
After parking, the reasons for noise from the rear wheel position are as follows: Foreign Object Accumulation: Excessive accumulation of foreign objects on the mudguard or sound insulation pad. When the car turns, the tire interferes with these objects, causing abnormal noise. The noise disappears after cleaning the mudguard. Screw Loosening: Fastening screws of the mudguard or sound insulation pad have come loose, causing the mudguard or sound insulation pad to lift. During turns, the front wheel interferes with and rubs against them, producing abnormal noise. It is necessary to check the fastening condition of the mudguard and sound insulation pad and eliminate factors such as looseness and lifting. Unauthorized Modifications: Unauthorized modifications to the car tires, such as replacing them with non-original size tires. For example, widening the tires or increasing their diameter may cause interference between the tires and the car body at certain positions during turns, resulting in noise. This poses a significant safety hazard, and the original size tires should be reinstalled.
I've been dealing with car issues for several years, and it's quite common to hear noises from the rear wheel area after parking. In most cases, it's a squeaking sound caused by the brake discs contracting as they cool down. The friction from braking during driving heats them up, and when you park, the temperature drops, causing the metal to contract and produce noise—this is usually normal. However, it could also be due to worn wheel hub bearings, especially after driving over bumpy roads; the bearings might emit a humming sound. If the noise is loud or persistent, you should check for any looseness or dry grinding in the bearings. Another possibility is the suspension system—for instance, if the shock absorbers are worn out or the springs are deformed, there might be a dull thud when parking due to changes in load. I recommend inspecting the wheels and surrounding components after parking, feeling around by hand to identify the general location of the noise. If anything seems off, take the car to a repair shop promptly for a thorough check-up to avoid potential issues on the road.
