What Causes Steering Wheel Failure?
3 Answers
Generally, it is caused by the steering system operating under excessive load, leading to excessive wear of the internal stator and rotor of the steering pump. This results in irregular movement of the oil inside the pump, producing abnormal noises. Common issues with power steering failure include: heavy steering, abnormal steering noises, and steering system oil leaks. Precautions for steering wheel failure: Reduce speed and stop: If the power steering system fails and the steering suddenly becomes heavy, quickly release the throttle, reduce speed, forcefully operate the steering wheel, and park the vehicle in a suitable location. Power steering failure does not affect fuel consumption: Since power steering is controlled by a computer, issues are more likely to occur in the circuitry, such as poor connections, damaged electric motors, or module failures. However, power steering does not affect engine load and does not increase fuel consumption.
A few days ago, I experienced a sudden stiff steering wheel on the highway—it was terrifying. After inspection, I found out it was due to a failure in the electric power steering system, where a faulty sensor caused the assist to disappear. Common issues also include hydraulic power steering fluid leaks; if the oil pump doesn’t have enough fluid while operating, it will fail. Rusty steering columns or stuck gears can also be culprits, especially in humid areas. That incident reminded me: if the steering fails, don’t force driving—slow down, pull over safely, turn on hazard lights, and call for assistance. Regular vehicle maintenance is crucial, like changing power steering fluid periodically and checking for electronic system updates. Safety is no small matter; develop sensitive habits—even minor abnormalities like heavier steering should prompt an inspection.
Having repaired many cars, I've found that steering wheel failures are mostly due to issues with the power assist system. In hydraulic systems, common problems include aging oil pipes, oil leaks, or pump damage; in electric systems, it's often sensor failures or control module malfunctions. Loose steering columns or improper gear meshing can also cause issues. Imbalanced tire alignment adds extra strain. For prevention, I check the power steering fluid level every six months and listen for unusual noises during steering. Address problems early—don't wait until complete failure occurs, as the risk of dangerous driving is too high. Maintenance is key, especially for older cars where insufficient lubrication can easily lead to failures.
