What Causes the Squeaking Noise When Turning the Steering Wheel in a Mistra?
3 Answers
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 Hyundai. 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 maintenance, 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.
