The reasons for the squeaking noise when turning the steering wheel in a Mistra: 1. The steering column lacks lubrication, resulting in high friction; 2. Insufficient power steering fluid; 3. Issues with the universal joint; 4. Aging and hardening of the rubber bushings in the suspension stabilizer bar links; 5. Failure of the plane bearing. The Mistra is a family sedan under Beijing . Taking the Mistra 2019 1.8L Automatic Smart GLS National VI as an example: its body structure is a 4-door, 5-seater sedan, with exterior dimensions of 4710mm in length, 1820mm in width, and 1470mm in height, a wheelbase of 2770mm, a minimum ground clearance of 152mm, a fuel tank capacity of 62 liters, and a trunk capacity of 526 liters.

I've encountered a similar issue before. A squeaking sound when turning the steering wheel is usually caused by insufficient lubrication on the steering column or a damaged dust boot. When dust and debris get inside, the friction creates this noise. Additionally, for hydraulic power steering systems, low or aged power steering fluid can also cause abnormal noises. I recommend checking if the dust boot has any cracks and trying to spray some lubricant on the steering column joints - this simple fix might provide temporary relief. If the noise persists, it could indicate worn steering bearings, which require professional tools for inspection and repair. It's best to visit a repair shop as soon as possible to avoid major issues, since the steering system is crucial for driving safety. For the Mistra model, the electric power steering module can sometimes develop minor faults too, so thorough troubleshooting is needed.

My Mistra also used to squeak when turning the steering wheel, and it turned out to be a small crack in the rubber dust boot of the steering column, which allowed sand to get in and cause friction. If you want to fix it yourself, you can first try cleaning out the dust and spraying some lubricant to see if the noise goes away. If that doesn't work, it might be because the power steering belt is loose or severely worn, and it will need adjustment or replacement. This issue is more common in winter when the air is dry. Remember to check these parts during , as simple upkeep can save you a lot of trouble. After I spent a few dozen bucks on lubricant and fixed it, the noise never came back. Don't delay too long, or you might end up with more problems in the steering system.

The squeaking noise when turning the steering wheel is mostly caused by dry friction in the steering components. For example, lack of lubrication in the steering column joints, damaged dust boots, or aging bearings. For cars like the Mistra, poor contact in the control module of the electric power steering system can also cause noise. It's recommended to have check the lubrication during regular maintenance and apply specialized oil as a preventive measure. While driving, pay attention to the location of the noise—whether it's on the left or right side—to pinpoint the source of the problem for more efficient repairs. Ignoring these issues can significantly reduce steering efficiency and compromise handling safety.

A squeaking sound could be an early warning sign of steering system issues. If it's caused by friction in the steering column or bearings, lack of lubrication, or damage, it can severely affect steering smoothness. Ignoring such abnormal noises may lead to deformation of steering components, posing significant driving safety risks. The electric power steering design of the Mistra requires checking for loose connections. If problems are found, avoid DIY repairs—safety first—and immediately visit a professional workshop for diagnosis and potential part replacement. For prevention, adhering to regular intervals can help reduce such failures.

A squeaking sound when turning the steering wheel is commonly caused by lack of lubrication in the steering column joint or a torn dust boot. You can perform a preliminary check yourself: find a quiet underground parking lot and turn the steering wheel to locate the sound source. If it's dry friction, spraying some WD-40 might provide a temporary solution. However, deeper issues like bearing wear or loose belts require professional mechanic attention. In the Mistra model, aging electronic power steering components may also cause abnormal noises. Don't delay too long - small problems can turn into expensive major repairs. Address it promptly to ensure steering system stability.
