Every vehicle has a steering system which gives the driver control over the direction in which they are driving. If you don’t have a functional steering system, then it will create all kinds of problems for you. More importantly, it will make your vehicle unsafe for yourself and the other people on the road around you.
Just imagine having to make a turn or trying to change lanes and then having the steering wheel hard to turn all of a sudden or even locking up. This can cause an accident to the point where someone could be injured or even killed.
The most common problem with the steering wheel is that it can become difficult to turn. Since most drivers do most of their turning at low speeds, this is when tight or stiff steering wheel will be most noticeable. It is a clear indicator that you have some type of problem somewhere in your power steering system.
There are many components which make up the power steering system. Aside from the serpentine belt and the pump, the system contains hydraulic power steering fluid which works alongside the piston so that you can easily turn the wheel with little resistance.
If there were to be an issue with any one of these areas of the system, then you wouldn’t get the assistance of the power steering to make turning the wheel easier.

Common Causes of a Steering Wheel That’s Hard to Turn at Low Speeds
It’s important to understand the main causes of a hard to turn steering wheel. Below are the top 5 reasons that your steering wheel is getting more difficult to turn. You’ll want to go through this list and troubleshoot the issue as soon as possible.
#1 – Low Power Steering Fluid
Perhaps the most common cause of a stiff steering wheel when turning is when you don’t have enough power steering fluid in the system. Usually, this occurs if the fluid is leaking from the pressurized hose area. Sometimes the hose will get cracked or simply become loose, causing the fluid to leak out.
Since this fluid is needed to pressurize the system and lubricate the pump, you will have a steering wheel that gets harder to turn the less power steering fluid you have in the system. The car may be drive-able but if you don’t fix the leak, it will eventually cause your power steering pump to fail which can be an expensive replacement.
If a quick check shows that your power steering fluid is full, keep reading.
#2 – Bad Steering Rack
The steering rack is made up of the pinion and rack. A series of U-joints and shafts keep the steering rack attached to the steering wheel. The steering rack will eventually become worn out and damaged from simply driving your vehicle over the years.
You will know when this happens if your steering wheel is only stiff or tight after you’ve started your vehicle. As the engine continues to run and warms up, the steering rack will get hotter which causes the lubricant to work itself around a bit better. Therefore, the steering wheel may become less stiff as the car continues to run. But still, you’ll need to get the steering rack replaced before the problem escalates.
#3 – Broken Serpentine Belt
One of the most common causes of steering wheel stiffness is when the serpentine belt is damaged or cracked. This belt is constantly being used when you drive the vehicle so over time, it gets worn down pretty quickly.
This in turn will cause it to become loose which is when the stiffness in the steering wheel will begin. If you don’t replace the belt soon, it will break altogether and then you won’t be able to drive your car at all. It’s better to replace the belt before this happens.
#4 – Power Steering Pump Failure
The pump of the power steering system is what produces the amount of pressure needed to allow you to smoothly turn the steering wheel. If this pump were to stop working, then it will become much more difficult to turn the steering wheel, especially at low speeds.
Normally, in these situations, the pump won’t prevent the steering wheel from moving completely. You will still be able to turn it, but it will require a lot more force on your end. The heavier the vehicle, the harder it will be to turn the wheels. Before a costly power steering pump replacement, make sure the connector to the pump simply didn’t wiggle itself loose or get damaged.
#5 – Old Thick Power Steering Fluid
Like other fluids in your car, power steering fluid can become thick over time. If you don’t change your power steering fluid according to what your car manufacturer recommends, then it will eventually become too thick to lubricate the system.
This will cause your steering to be tight and more difficult to turn at low speeds. If a quick check of your fluid shows it’s dark and thick, you’ll need to flush and change your power steering fluid as soon as possible.
