Today we're going to talk about power steering service in Northville. If you took an informal poll around Northville you'd probably find that most vehicle owners have never heard of power steering service. That's not surprising. Even though power steering is standard on every vehicle, most people in Northville aren't aware that it needs periodic service.

If you're younger than a certain age, you've probably never driven a vehicle without power steering. To get an idea of the difference; if you've ever cut a board with a hand saw, you know it's a lot of work. Using a power saw is easy-peasy by comparison.

Without power steering, your arms have to do all the work to steer the wheels, and that's hard, especially around downtown Northville. That's why old cars had such big steering wheels: to get enough leverage to steer.

Most vehicles in Northville have a hydraulic power steering system. The serpentine belt from the engine powers a pump. The pump pressurizes the power steering fluid. This actuates a hydraulic cylinder that provides power to help steer.

Some vehicles in Northville use an electric pump to pressurize the fluid rather than a belt driven pump. We're also seeing vehicles with electric motors providing the power assist, not using power steering fluid at all. We'll see a lot more electric systems as more hybrids and electric vehicles hit the market.

At least for now, the vast majority of power steering systems use power steering fluid that needs to be serviced. The fluid needs to be changed for a couple of reasons. For one, it attracts moisture. Water has different hydraulic qualities than power steering fluid, and that makes a difference in steering performance. Water is also corrosive and can damage power steering components. The fluid also just gets dirty and needs to be changed. Removing the old fluid and flushing out the system gets rid of dirt and deposits. The clean, fresh fluid lubricates and provides better corrosion protection.

So ask your Northville service advisor at Tuffy Northville or check your owner's manual to see when power steering service is recommended. It'll extend the life of your power steering components.
