Change your power steering fluid
The unwritten rule is to change your steering fluid every 2 years or by driven 24 000 miles. Fluid change interval is very important, and you should adhere to your car’s service book recommendation in order to maintain it in correct condition. It’s very important to follow up as it could get extremely dangerous to drive with bad, old fluid because it could make steering wheel unresponsive and slow.
If it has become harder to turn the steering wheel, you hear the squealing noise, or in the worse scenario already grinding noise, you should check fluid levels immediately as power steering may fail any moment. You can try to change the power steering fluid yourself, but beware that you might not identify the potential root cause of the noises you hear. Best is to leave it to specialists to deal with.
