What Causes the Noise from the Rear Wheel Position After Parking?

[DelBrady]

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.

I've encountered similar situations while driving myself. After parking, there was an abnormal noise from the rear wheel area, which could be due to several reasons: First, the clicking sound caused by the cooling of brake discs, especially noticeable after the car has been hot in summer—this is a normal physical phenomenon. Second, unstable tire pressure or a stone stuck in the tire tread, which makes noise when the pressure is released upon parking; last time, it was a stone stuck in mine, and pulling it out solved the problem. Third, loose wheel hub bolts that need regular tightening. During inspection, first check the tire pressure and bolt tightness simply; don't rush to tow it to the shop. If the noise is very loud or accompanied by shaking, it might be a bearing failure or suspension issue, requiring professional handling. Regular maintenance of the wheel area can reduce such troubles.

As a parent, I place great importance on driving safety. After parking, there's a noise coming from the rear wheels, which is quite annoying, but more importantly, it shouldn't be taken lightly. It could be due to leaking shock absorbers in the wheel suspension or fatigued and deformed springs, where changes in gravity when parking might cause unusual sounds. This could affect steering control, and if something goes wrong while driving to pick up or drop off the kids, it could be very dangerous. I recommend immediately parking in a safe place and checking for any loose components under the chassis. If the cause isn't clear, contact a repair shop right away to schedule an inspection. Prevention is key—regularly change the oil and maintain the suspension system, especially after long-distance driving. Safety comes first; spending a little money can bring peace of mind for the whole family.
