Solution: Abnormal engine noise indicates that the technical state of a certain engine mechanism has changed. This is mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can even predict potential catastrophic damage to the engine. Therefore, when abnormal noise occurs in the engine, it should be repaired promptly to prevent the fault from worsening. Here are some tire maintenance suggestions: 1. When replacing a new tire, it is best to perform a four-wheel alignment to prevent tire wear or edge wear. 2. Check the tire pressure once a month, which should be between 2.2 and 2.8. The pressure on the same axle must be the same to prevent running deviation and uneven wear. 3. Occasionally use a hard object to pick out stones stuck in the tread. 4. Pay special attention when the tire is punctured by a nail or other objects; it is best to replace it with a spare tire promptly.

I always get nervous when I hear strange noises from the left front wheel while driving, especially those squeaking or knocking sounds when turning or going over bumps. There could be many reasons, like small stones stuck in the tire, or rust flakes on the brake disc lightly scraping the wheel hub. It's best to stop and check the tire surface for any foreign objects first, and try to remove them. If it's a continuous whining sound, the wheel hub bearing might be worn out and needs replacement. Safety comes first—don't push through and drive to check; go directly to a repair shop for a diagnosis using a lift. Regular checks on tire wear and pressure can help reduce such issues.

Handling car issues myself is my joy, and don't take the abnormal noise from the left front wheel lightly. Common causes include uneven brake pad wear causing squeaking, or aging shock absorber bushings leading to vibration sounds. I recommend lifting the car first and shaking the wheel to check for looseness. If the bearing is loose, the noise will be quite obvious. Tightening screws is also crucial; sometimes slightly loose wheel hub screws can solve the problem. Cleaning foreign objects from the brake part is simple—just spray some brake cleaner. However, key components like bearings require professional tools for replacement when they fail.

A squeaky left front wheel should never be ignored, as it directly affects handling and could even lead to accidents. Common causes include brake system issues or axle wear—I've encountered these in many cars I've driven, and timely troubleshooting is essential. The easiest solution is to take it straight to a repair shop for a circuit check with a multimeter or an undercarriage inspection on a lift. Don't delay; safety comes first. For prevention, regular wheel balancing and tire pressure monitoring can reduce the risk of squeaks.
