Can You Drive Without Power Steering?

Yes. You can drive without power steering, but it is considered risky. Driving without power steering can be difficult. You should only try to drive if necessary. 

If you are driving, go slowly, avoid any sudden maneuvers or turns, and decrease the number of miles you drive on these types of roads. 

You should also decrease your speed by about ten mph on roads with steep slopes to prevent the car from rolling down the hill due to a lack of power steering. 

It’s important not to park your vehicle on a slant or incline because that will result in it being more difficult for you to push it back into straighter alignment once it’s parked, which could cause damage. 

Your transmission will also have difficulty turning uphill, so it is best to avoid these areas as well.

Finally, consider if you need to drive on these roads. If you do, get in and out as quickly as possible. 

Driving on a steep hill will take more gas and effort to go forward or backward. While operating your vehicle without power steering is possible, using it wisely and sparingly is the best way to drive safely on steep inclines.

What Is Power Steering?

Power steering, or power-assist steering (PAS), is an automotive technology that can reduce the turning radius of a vehicle by allowing a smaller wheel hub to turn more than it would normally.

Handling cars in tight spaces, such as inside parking garages is necessary. When the vehicle turns at a tight angle, control over torque from the engine and wheel speed is lost due to the increased friction between the tire and floor. 

This makes it difficult for the driver to maintain vehicle control even with minimal application of accelerator or brakes. 

Additionally, this friction can cause camber angles on one side of the car to be higher than on the other. This can make it difficult for the driver to steer the vehicle on a straight path. 

Power steering reduces both of these problems because it allows the wheels to be moved by a chain or belt-driven by an electric motor, decreasing the effort needed to turn them. 

Power steering is found in almost all modern cars and has been used in other vehicles, including trucks, buses, and cars with large wheels, such as motorcycles.

Learn More About Power Steering

Power steering systems are designed to improve the efficiency of vehicles by reducing fuel use, improving and stabilizing ride quality, and increasing safety. 

A power steering system uses an electric motor connected to a fluid coupling that enables the displacement of power from the engine to the wheels through a worm gear or rack-and-pinion mechanism. 

The electric motor receives power from an auxiliary battery or engine when it is not receiving input from the driver. This system requires no mechanical connection between the wheels and generally uses larger vehicles such as tractor-trailers and buses. 

Power steering systems can be found in both rear-wheel drives and front-wheel-drive cars. Power steering systems require less energy than manual steering as they reduce the effort needed to turn or steer at low speeds. 

It also improves safety by reducing the driver’s fatigue and the need for extended muscles to hold the steering wheel during long periods of motor vehicle operation. 

The addition of power steering significantly increases driving comfort, especially at lower vehicle speeds.

Power steering systems are also found in retrofit applications on older cars and light trucks. 

Examples include:

  • Adding an aftermarket rack-and-pinion system to a classic car.
  • Adding a power steering unit to a classic muscle car, particularly a Ford Mustang.
  • Replacing manual steering with an electric power steering unit on a truck. 

The electric motor is usually powered by conventional batteries in these applications and drives the pump using an adapter fitted over its output shaft.

What Should I Do If Power Steering Fails?

If your power steering fails while driving on the highway, park your car inside first and call the mechanic to fix it immediately. 

A power steering system is responsible for the movement of your car. If power steering fails, it will be impossible to make any turns at all. Keep in mind that this could happen anytime, Even if you are coming to a stoplight or trying to change lanes. 

The pump likely fails if your steering becomes very stiff and allows for little to no turning radius. If you have no power assist at all, there is either a problem with your fluid level or a belt slipping issue. 

What Happens When Power Steering Fails?

Your power steering pump may fail if you have recently changed your fluid. Always keep a bottle of fluid in your car while the car is parked. This will allow you to maintain a decent fluid level and avoid blowing a seal on your pump or significant component.

Power steering pumps are known to fail on cars, trucks, and SUVs. If you think that your power steering is failing, you must schedule an appointment with a mechanic as soon as possible to diagnose the problem and make the necessary repairs.

Signs Your Power Steering Is Failing

The most common symptom of power steering failure is a rough, jarring ride that increases with speed and becomes significantly worse when the vehicle goes into turns. 

Often, power steering can fail gradually over time but will usually become noticeable by itself if it fails. 

If you notice your speedometer or other gauges wavering before or during turns, or if your car jerks unexpectedly, it might be time to replace the entire system. 

Here are some of the signs that your power steering is failing:

  • Hard Steering

Hard steering is a sign that a car’s power steering system is failing and means it may be leaking fluid. A leaking power steering system has been known to cause further problems, like bent wheels or broken axles. 

  • Whining Noises 

Whining noises are another common sign of a steering failure. When your car’s power steering system is exposed to heat, it becomes less efficient; more heat, and more noise. Heat in your power steering system can make your rack and pinion turn too quickly. 

  • Fluid Leakage

If your power steering system leaks fluid, it’ll drip down from the reservoir onto the bottom of your vehicle. The fluid will then flow past the pump, where it’ll drop down through your power steering unit and can leak out of the bottom of your car. 

If your power steering is leaking fluid, it’s probably because one of the seals in the power steering unit has burst or worn out. If this happens often enough, you need to fix the car immediately. If these occur frequently or get worse, contact a professional for a quick fix.
