How to Solve the Abnormal Noise of the Power Steering Pump?
2 Answers
If there is abnormal noise in the power steering pump, the filter should be cleaned or the pump should be re-secured. Below are the specific reasons for weakened power steering in a car: 1. Dirty power steering fluid: The fluid acts as a force-transmitting medium. If the fluid is too dirty, it can cause poor circulation, making steering difficult. In severe cases, the power steering pump may also produce abnormal noise. 2. Insufficient or leaking power steering fluid: Lack of fluid means lack of power assistance. Check the related systems for any signs of leaks. Pay special attention to the power steering fluid reservoir, fluid lines, and steering gear. 3. Loose or tight power steering belt: Alternatively, the belt may be worn out. The tension can be adjusted, but a worn belt must be replaced.
Speaking of power steering pump noise, I've seen it too often in the garage. The most common causes are insufficient power steering fluid or air bubbles getting in, which creates a gurgling sound when driving. Worn or loose belts are another major factor, producing squeaking noises. First, check if the fluid level in the reservoir is between the MIN and MAX marks—top it up with the correct fluid if low. For belt issues, press on it; if too loose, adjust or replace it. Sometimes, worn bearings inside the pump cause a humming noise—in that case, get it checked at a repair shop immediately to avoid sudden steering failure. Make it a habit to inspect fluid levels and belt condition every six months to save yourself a lot of trouble.
