What Is A Tie Rod? What Does It Do in Your Vehicle?

When you are driving your loving car on the road while listening to your favorite music, the feeling is unparalleled. You feel like all the stress and worries of your life just disappeared for a moment. Yeah, I know all the car owners out there are familiar with such feelings.

But when you are enjoying those, you would also want your car to follow your command and not to hit the poor cow passing by, right?

So, when it comes to making sure of that, do you know what part of your car plays the most significant role? Yes, It's the tie rod. In this article, we will learn what a tie rod is and what it does in your vehicle. So, let's get started.

What Is Tie Rod?

The tie rod in your car is an essential part that links the vehicle's steering knuckle to your steering rack on the front wheels. And the tie rods outer and inner ends surround an adjusting sleeve. When you rotate the steering wheel of your car, it enables movement all around the system.

The wheel turns by the push and pulls activity of the rods. You know, it would be impossible to drive your vehicle if you are unable to turn the steering wheel unless you are some superheroes. Therefore, it's understandable how essential the tie rods are in your vehicle.

How Do Tie Rods Work?

You already know that a tie rod is a significant part of your vehicle's steering system. I guess the name explains its purpose pretty well. Yes, it ties the steering rack of your vehicle to the steering arm.

And the steering arm is connected to your wheel. You will find 2-types of steering systems in a vehicle one is re-circulating ball steering and another rack-and-pinion steering. Here's how they function:

Rack-And-Pinion Steering

The rack and pinion follow a very simple mechanism. When you turn your vehicle's steering wheel, the pinion gear connected to the steering shaft will start to roll along with your steering rack.

And the steering that is connected to both your front wheels will move by following the way you turn the wheel. Tie rods are also in charge of transmitting the force to the steering rim from your steering rack and move them to the wheel.

Re-Circulating Ball Steering

The re-circulating ball system is a bit complicated compare to the rack and pinion system. It incorporates a gearbox. When you turn the wheel, the steering shaft will arrange multiple gears in motion. And that pitman arm will move your steering rack following the way you steer.

This system is also attached to the tie rods and, they are connected to the steering wheel just like the rack and pinion system. And those are also attached to the steering arm.

The main connection between your steering system to the wheel is the tie rod. Tie rods are like the backbone of your steering system. You cannot imagine your steering system without your tie rod.

If you have heard about pivot points that stay between the steering arm and steering system, then that's exactly the tie rods. Your outer tie rod end comes with an adjustable feature.

So, if you have to fix the alignment, you can do that just by changing the length of the tie rod. Tie rods let you move your wheel and make the vehicle turn. I hope you have no more questions about its essentiality.

What Happens If Your Tie Rod Breaks?

So, what would exactly happen when this significant part of your vehicle breaks? Well, you know, what would happen if you leave your gun at the barrack when going to the battlefield. Likewise, it would be best if you never went to the road with your vehicle when its tie rod is broken.

Most of the time, it's your outer tie rod ball joints that go bad. When your tie rod goes bad, you will lose the ability to steer the wheel on the side where the tie rod is damaged.

The moment your tie rod breaks the wheel where it's attached will lose all control from the steering assembly. It will just flop around be based on the tire wear, vehicle speed, pressure and road condition, etc. To be more specific, when the tie rod will fail, you lose your usual ability to steer the vehicle.

When Does the Tie Rod End Need to Be Replaced?

As a responsible person, you should regularly check the steering system of your vehicle to ensure your and your family's safety. When driving, if you notice wandering, pulling, or any trouble in steering, you should immediately inspect the steering system.

To do that, firstly raise the front end of the vehicle and try moving the front wheel back and forth. If you feel free to play or excessive movement then, you should check the tie rod ends.

When the vehicle is parked, try turning the steering wheel back and forth and, if it makes any thudding or clunking noise, it's probably your tie rod ends that got worn or loosen. Another two big signs of bad tie rod ends are front end vibration and noise.

And if you can't return your steering wheel to the center, then it's time to inspect your tie rod ends. If you can manage to do these early maintenances, you would be able to get rid of any further damage and driving risk.
