What does it mean when there's abnormal noise during cold steering that disappears after warming up?
2 Answers
The reasons for abnormal noise during cold steering that disappears after warming up: It could be due to the power steering fluid level being too low or the power steering pump not working properly, causing noise when turning the steering wheel. It might also be caused by insufficient engine lubrication when the car is cold, as the oil settles at the bottom. It is recommended to observe the issue for a while longer. If the problem worsens, take the car to a 4S shop for inspection and repair. Method for replacing power steering fluid: 1. Open the car's front hood and use an oil extractor to remove the old power steering fluid completely. 2. Inject new power steering fluid, then turn the steering wheel back and forth to allow the new fluid to penetrate. 3. For thorough penetration, it's best for the driver to turn the steering wheel sharply left and right, then gently turn it left and right. 4. Then, remove the fluid from the power steering reservoir and inject new fluid again, turning the steering wheel once more. 5. Remove the fluid again, ensuring that the old fluid is completely cleared out on the third extraction. 6. Finally, inject new fluid.
I've been driving for over a decade and often encounter squeaky steering wheels when starting the car in cold weather, which quiets down after driving for a while. This is mainly because steering system components like ball joints or tie rods contract and harden in low temperatures, increasing gaps and causing friction noise. Coupled with thickened lubricant providing insufficient lubrication, the abnormal noise occurs. After the car warms up, components expand, gaps reduce, and oil flows better, making the noise disappear. Older cars are more prone to this issue, with common causes being aged steering knuckle rubber or oil leaks. It's recommended to regularly check that steering fluid isn't too low, and replace torn dust boots promptly to prevent mud and water from accelerating wear. When parking, try to avoid damp and cold places to reduce rust. If the abnormal noise persists or worsens, visit a repair shop to check it out to avoid affecting handling safety.
