What Causes the Squeaking Sound When Steering in Reverse?
2 Answers
The reasons for abnormal noises when steering in reverse are as follows: Most hydraulic power steering pumps exhibit this phenomenon. When turning the steering wheel, the power steering fluid cannot circulate smoothly, resulting in this squeaking sound. It could also be the sound of friction between the combination switch housing and the steering wheel. Loosening the housing screws and adjusting them slightly may resolve the issue. Additional information: 1. A car power steering pump is a component that helps improve and stabilize vehicle performance. It primarily assists the driver in adjusting the car's direction. Currently, most cars are equipped with power steering pumps, mainly including the steering power pump and the brake vacuum power pump. 2. The electro-hydraulic power steering system overcomes the shortcomings of traditional hydraulic power steering systems. The hydraulic pump it uses is no longer directly driven by the engine belt but instead employs an electric pump. All its operating states are calculated by the electronic control unit based on signals such as the vehicle's speed and steering angle to achieve the most ideal condition.
I've been driving for over a decade and often pay attention to such strange noises. The creaking sound when reversing while turning the steering wheel is mostly due to wear and tear in the steering system components, such as aging or loosening of the steering column's ball joints. It might be fine during normal driving, but reversing puts more stress on these parts, making the issue more noticeable. Another possible cause is increased tire friction, like on slippery surfaces or when small stones get stuck in the wheel hub, making the noise louder. A common reason could also be fatigued suspension springs, which produce noise under pressure. I've encountered this before—once I stopped and felt around the linkage area, finding some looseness, and after simply adding some lubricant, it became much quieter. For safety, don't push it; getting it checked and repaired early at a professional shop can save you a lot of trouble.
