What Causes the Steering Wheel to Make Noise When Turned to the Full Lock Position?
2 Answers
Here are the reasons why a car's steering wheel makes noise when turned to the full lock position: 1. Sound from the turn signal reset: If the turn signal is activated while turning, this sound is produced by the reset mechanism's spring clip. 2. Sound from interference with the clock spring: Remove the steering wheel's clock spring and apply some grease to see if the noise persists. If it does, replace the clock spring. 3. Sound from the steering wheel: Unusual noises originating from within the steering wheel. 4. Sound from the steering column dust cover: Lack of lubrication in the steering column dust cover can cause friction noises. In this case, applying some grease inside the dust cover will eliminate the noise.
I've encountered this issue of strange noises when turning the steering wheel to its limit quite often. When you fully turn the wheel while driving, it may produce squeaking or humming sounds, usually caused by the steering system operating under high pressure. The most common scenario is with hydraulic power steering – when the power steering fluid is insufficient or the pump is aging, it can make noises, almost like it's crying for help. Additionally, if the steering linkage or ball joints are worn, increased friction during turning can also cause noises, especially noticeable during cold starts in winter. Another possibility is an issue with the electric power steering motor, commonly used in modern vehicles – poor electrical contact can lead to noises. Don't ignore it, as prolonged neglect can accelerate part wear and even compromise safety. I recommend first checking the power steering fluid level. If that's fine, take it to a professional shop immediately for a technician to diagnose with proper equipment – don't let it escalate into a major problem.
