What Causes Steering Gear Abnormal Noise?
2 Answers
Steering gear abnormal noise can be caused by lack of lubrication in the dust cover, insufficient or contaminated power steering fluid, or a faulty power steering pump. Below are detailed explanations: Lack of Lubrication in the Dust Cover: When the dust cover lacks lubrication, it can cause friction noise. In this case, simply applying some grease to the dust cover will eliminate the abnormal noise. Insufficient or Contaminated Power Steering Fluid: Leakage of power steering fluid leading to insufficient oil level, low oil pressure, or excessive contamination can cause lack of lubrication in the steering gear components, resulting in friction noise. It is necessary to check the power steering fluid and replace it if needed. Faulty Power Steering Pump: A faulty power steering pump can produce abnormal noise due to pressure leakage.
I've been driving long-distance for decades and have seen many cases of steering noise. The most common issue is insufficient or dirty power steering fluid—just topping it up with fresh fluid often solves it. Another frequent cause is wear and tear inside the steering mechanism, like loose bearings or damaged gears, which create squeaking sounds when turning. If the tie rod ends are severely worn, you'll hear a clicking noise when steering. Other possibilities include low pressure from the power steering pump or aging suspension components affecting the steering system. A word of caution: this isn't a minor issue. At best, it leads to unstable handling; at worst, it could cause accidents. Get it inspected and parts replaced at a reputable shop ASAP. Develop a habit of regular maintenance—checking the power steering fluid level during every oil change can save you a lot of trouble.
