How to Separate Hydraulic Noise From Mechanical Noise in Steering Systems

Identifying and eliminating the power steering noise can be downright maddening if you don't know what's causing it. Determining if your power steering noise is caused by the hydraulic system or some mechanical issue can help. Here are the steps to take to separate and eliminate the source of the power steering noise in your car.

Instructions

1. Listen carefully to the noise. If it is a humming type of noise it may be a pump and hydraulic issue. If it is more like a crunching sound, it might be a mechanical problem.

2. Try installing a noise suppressor to the hydraulic system. If that takes care of the noise, then you have solved the problem. This might consist of housing and a sound deadening material.

3. Check the color and consistency of the power steering fluid which can lead to hydraulic problems in the system. Inspect the fluid for sludge and other dirt and debris, all of which can adversely affect the system's performance.

4. Change the power steering fluid and take the time to flush the system. This will eliminate any dirty fluid that might be causing problems with hydraulic noise. Check all hoses and pressure lines for wear and replace as necessary.

5. Take the vehicle to your mechanic and have him analyze the noise if you've tried everything and still cannot locate the source of the power steering or mechanical noise. It might be worth the few buck you'll pay him to save you the headache of trial and error on your part.
