While most power steering is hydraulic, some newer vehicles now have electrical power steering. A key component of hydraulic power steering is to have regular servicing done, proper fluids installed and to make sure there are no leaks in the system. Most power steering failures can be caught in advance by preventative maintenance which involves checking for a faulty pump seal or spotting irregular belt wear.
Some signs that you need to have your power steering serviced are:
- A growling or whining sound while steering
- Any kind of fluid residues left while sitting
If these symptoms are ignored, the end cost of a repair will increase and inconvenience you at the worst possible time.
