Steering wheels on cars in the earlier days were much bigger than they are now. It took a lot of muscle to turn the steering wheel, especially when the car was going slower. It wasn’t until the 1950s that power steering was invented. It took almost two more decades before power steering became standard on most cars. Here’s what to know about power steering.
Purpose and Function
Cars today have one of two types of power steering. In hydraulic power steering, a pump circulates power steering fluid through a complex system of valves, pulleys, a piston and cylinder. When you turn the steering wheel, the fluid exerts pressure on one side of the system, allowing the car to turn easily. When the car isn’t being turned, the piston is in a neutral position, just like the steering wheel. Electric power steering uses a motor instead of hydraulics to make it easier to turn the wheel. Electric power steering is not as common as hydraulic power steering. It’s currently estimated that about 30% of cars have electric power steering. Check your owner’s manual to know what type of power steering your car has and what type of fluid is required in the system.
Should You Drive Without Power Steering?
Although you can technically drive your car without power steering, it is illegal to drive without it. Without power steering, you put other drivers at risk, because you can’t control your car as well. Without power steering, you lose reaction time. It can also damage your car. If you notice the signs of your power steering pump failing, get your car to your mechanic to get it fixed before you completely lose power steering. Find parts for your car and a wheel lock key at a local auto store.
Signs of Power Steering Pump Issues
Electric power steering systems generally work or not. You probably won’t notice any problems until the steering is difficult. Hydraulic systems may show symptoms of failure before they actually quit working.
- Your steering wheel may be difficult to turn.
- The wheels don’t respond to the steering wheel. It might seem as if there’s some slack in the time between turning the steering wheel and the wheels turning in the right direction.
- You have to add power steering fluid to the reservoir more frequently. It’s likely this is a leak in the system. It’s only going to get worse.
- You may hear noises when you turn the steering wheel, such as grinding or screeching.
- Your steering wheel may vibrate when you’re driving.
Take care of your power steering by getting maintenance according to the manufacturer’s recommendations. Change the power steering fluid every 40,000 to 80,000 miles. Watch for signs of failure to make repairs before things get worse. Invest in your car for a smooth and safe ride. Find a wide range of auto accessories, such as rain guards, power steering pumps, batteries and more to take care of your vehicle and to keep it operating at peak performance.
