Why is my power steering fluid leaking？What color is power steering fluid when it leaks? How To Fix Power Steering Rack Leakage?

Nowadays, most of the vehicles you see on the road utilize a rack and pinion steering system that features power steering.

The purpose of power steering is to make the car easier to steer. Unfortunately, this feature adds complexity to the rack and pinion system.

Because of this, issues with the rack and pinion power steering can often lead to expensive and complex repairs.

Adding power steering to a rack and pinion system changes the design a bit. A cylinder with a piston is installed in the rack. Then, fluid is added to both sides of the piston.

Adding pressure to the fluid will force the piston to move. This turns the rack and helps with steering.

1 What is the Rack and Pinion?

First of all, it’s best to understand what a rack and pinion steering system are.

For those who don’t know, car manufacturers utilize rack and pinion to transform the rotating movement of the steering wheel into linear movement.

Then, the tie rod of your car utilizes this linear motion to push the steering knuckle right or left. In turn, this will cause your front wheels to move in the direction you want.

As the name implies, the rack and pinion steering system utilizes a rack and a pinion to perform this task.

A pinion is just a tiny gear that you can find at the end of the steering column. Its purpose is to rotate whenever you turn your steering wheel.

On the other hand, a rack is a flat gear on which the pinion rests. Whenever the pinion rotates, the gears mesh with each other. This produces a linear motion required to turn your front wheels left or right.

Since it’s an important part of your car, when there’s a problem, you’ll need a rack and pinion repair service.

2 What Happens if Your Rack and Pinion is Faulty?

As a car owner, it’s crucial to be wary of what happens if your rack and pinion become faulty.

You might have a hard time steering your car whenever your rack and pinion is on the verge of a breakdown. However, you’ll completely lose control of steering if the steering system goes out.

Of course, you know what happens when you can’t steer your car, right? It can be dangerous and even fatal.

Because of this, it’s always ideal to avoid driving a car that has a faulty rack and pinion steering system. Even if the issue is minor, it’s a wise move to fix it right away before driving the car.

Just like any system that utilizes high-pressure hydraulics, the power steering system utilized in your rack and pinion can also be susceptible to leaks.

3 How To Determine if You’ve Got a Power Steering Leak?

Determining if you have a power steering leak is quite easy. All you’ve got to do is to examine every steering rack seal of the areas prone to leaks. As mentioned earlier, you can find these seals in both the connection of the tie rods and in the steering column.

Also, you might have a hard time crawling under your car. To make your life easier, make sure you use ramps or a jack stand. Simply ensure that your car is secure before crawling under it.

You can easily find the rack and pinion steering of your car since it’s one of the lowest parts of your vehicle. There’s a huge chance that it will be simply under the oil pan of your engine.

4 Why Do Power Steering Fluid Leaking Happen?

As time passes by, parts in the rack and pinion steering system can begin to deteriorate as you frequently use them when steering and driving. This can lead to loose fittings.

Though your power steering system can begin to leak through cracks or at the connection points in the flexible lines and rubber hoses, there’s a huge possibility that it will begin to leak from one of the seals on your power steering system.

Driving conditions and environmental elements can result in your seals cracking, shrinking, drying out, or becoming loose.

Keep in mind that there are 3 primary factors that can lead to leaks. This includes:

• The seals between the rack and pinion and the steering column or around the tie rod connections can dry out, crack, shrink, or become loose.
• The connections can loosen.
• The lines and hoses are made from elastic rubber that could crack.

Also, it is ideal to take note that the leak isn’t coming from your rack and pinion system. Instead, it is coming from your power steering system. The reason for this is that the steering rack doesn’t need fluid. It only requires grease for lubrication.

5 How To Detect a Power Steering Fluid Leak?

You probably heard of the phrase “prevention is better than cure”. Well, this saying can also be applied when it comes to cars.

When you own a vehicle, finding the issue before it can get worse is the most crucial thing you can do. Luckily, the signs of a power steering rack leaking issue are easy to notice.

If you see any of the issues below, there’s a huge possibility that your car is leaking power steering fluid.

1) Low Fluid Level

Almost every car owner checks their coolant and oil level frequently. However, they often forget to inspect the level of their power steering fluid.

Proper power steering fluid level is vital to the longevity of your power steering rack and for your safe driving. Driving a vehicle with missing or low power steering fluid can lead to expensive repairs.

The power steering reservoir of your car is often equipped with an indicator. Thus, you have to ensure you examine it from time to time.

Because your power steering system is shut-sealed, you likely have a leak somewhere if the fluid level gets low.

2) Difficulty in Steering the Wheel

Another sign of a power steering fluid leak is the difficulty in using the steering wheel. As mentioned earlier, the purpose of the power steering fluid is to make turning the car a lot easier.

Any delay in this response or stiffness when turning can be an annoying experience and is typically an indication of a leak.

In addition to that, stiffness in the steering wheel can be dangerous and risky. This is particularly true if you have to make a sudden turn.

3) Whining or Grinding Sound

Every manufacturer out there designs their car to offer maximum comfort. They always ensure that every part of the vehicle won’t make any sound.

Thus, if you start to hear weird sounds from the steering system when you turn right or left, that is a sign of an issue. It could be a problem with the power steering fluid.

You should know that whining and grinding noise happens due to friction. One purpose of the power steering fluid is to lubricate the steering wheel, making it easier to turn.

You’ll hear these weird sounds if the steering fluid is leaking out.

4) Ignition Sound

Another method of identifying leakages of power steering fluid is the noise coming from the ignition.

Try to listen to your car when you turn it on. If you notice a squeaking noise from the steering pump, you have a leak in your power steering fluid.

5) Fluid on The Driveway or Garage

This is perhaps the most obvious sign that you have a power steering fluid leak. Whenever you notice reddish or pinkish droplets of fluid below your car’s engine, it means that you have a leak.

You will usually notice this if you park your car for a long period. For instance, you will notice this sign early in the morning after you park your car overnight.

Thus, it’s a wise move to look under your car once in a while to ensure you spot a leak early and get it fixed before it becomes a severe issue down the line.

When you notice any of the signs mentioned above, don’t hesitate to visit a reliable auto mechanic to get your issue fixed as soon as possible.

However, if you want to save money on labor fees, you can try to fix the leak on your own. This is particularly ideal if you’ve got the tools needed to do the job.

6 What color is power steering fluid when it leaks？

The color of power steering fluid when it leaks varies depending on the type of fluid in the system. Most power steering fluids are red or pink in color, but some are clear or amber. When the fluid leaks, it may appear as a dark brown or black color due to contaminants and debris that accumulate over time. However, if the fluid appears to be a light brown or milky color, it could indicate the presence of water in the system, which is a sign of a severe leak. If the power steering fluid is clear, it could be a sign of a new leak or a small leak that has not accumulated debris.

7 How To Fix Power Steering Rack Fluid Leakage?

Power steering issues often do happen and it makes it hard to steer your car effectively.
