A lot of vehicles on the road today are designed to operate smoothly.
When there’s something wrong with a part or system, it can be distracting, frustrating or worrisome.
The power steering system is one place where problems could crop up.
What does the power steering pump do?
The power steering pumps on Toyotas can produce a few thousand pounds per square inch (PSI) of pressure, depending on the required load.
The pump pushes the fluid through the hoses to the power steering rack and pinion, which is connected to the steering knuckles that move the steering wheel left or right.
How will you know if your power steering pump is bad?
As with any part on a vehicle, over time power steering system components can leak.
Some signs of power steering fluid leaks include low fluid and certain sounds when driving.
The first thing you may notice when you have a bad power steering pump is stiffness in the steering wheel and/or a whining noise. Any pump that runs dry will make a groaning or whining noise.
If you start to hear a whining noise while you’re turning, you should check your power steering fluids. This could mean that there’s a leak in your hoses, rack or pump.
If the system runs out of fluid or the power steering pump stops working, it can be hard to turn the steering wheel.
A lot of newer cars have electric power steering and the system is going to send a warning signal if there’s a problem.
Can I still drive if my power steering pump goes out?
You should not drive a vehicle if the power steering isn’t working.
Yes, the car will technically drive if you have a bad power steering pump. However, you will have a hard time turning.
If the power steering system is low on fluid, you do run the risk of ruining the power steering pump.
Is a power steering pump easy to replace?
We can’t say beyond a reasonable doubt that we can call replacing a power steering pump “easy”.
It depends on where the manufacturer put the pump. If the power steering pump is right on top, then it would just be a matter of taking the belt off (if it’s belt driven), unbolting the pump from the engine, and then replacing the unit. Power steering pumps look similar to alternators, so that’s the weight you’re looking at.
Sometimes, pumps are tucked way back and you have to take a lot of stuff apart to get to them.
Once the power steering pump has been replaced, there are follow up steps, such as making sure all of the air is out of the system.
How do I maintain my power steering system?
Doing proper maintenance on your power steering system, such as changing the fluid every 30,000 miles, will help prolong the lifespan of the components and can reduce the cost of replacing power steering parts.
With today’s vehicles being as high-tech as they are, you must use the correct type of power steering fluid. Otherwise, you could do damage to the system.
