Cars are wondrous machines, simple and yet complex. Even among EVs in which the mechanical bits are reduced, there are hundreds of parts that all work in conjunction with one another to create a beautiful ballet. One of the most interesting aspects of this dance is in your car’s steering system, a part known as a tie rod that brings it all together.
Tie rods are crucial components to your car’s two-step coordination. And when they go bad, they go bad hard and in a seriously dangerous way. But don’t fret, Car Bibles’ editors are here to explain what happens, what to look out for, and how much replacing bad tie rods costs. Let’s get to it.
What Is a Tie Rod?
A tie rod is a part of your vehicle’s steering system. Tie rods connect your steering gear, which is connected through a shaft to the steering wheel, and the steering knuckle, which turns the car.
How Does a Tie Rod Work?
As you turn the steering wheel, the steering rack behind the car’s firewall turns in concert. That rack is connected to the steering knuckle below, which is connected via a tie rod. The tie rod can be adjusted using its threaded design to align your steering system.
When Does a Tie Rod Need To Be Replaced?
Tie rods aren’t your average maintenance items. They’re designed to last the life of a vehicle, though external factors such as extreme weather, poor maintenance, and impacts and accidents, can affect their life cycles.
To determine if you need to replace your tie rods, you’ll need to first suspect there’s something amiss with your car’s steering, and then jack up your car. From there, it’s a pretty simple and straightforward process. Let’s elaborate.
The Symptoms of a Failing Tie Rod
Here are a few symptoms you might encounter when your tie rod fails.
Wheel Feels Loose When Lifted
If you lift up your car on a jack and can wiggle the wheel (not in the direction of the steering)you likely have a bad set of tie rods.
Uneven Tire Wear
And given that you likely can wiggle your tire, imagine that while driving. As such, you’ll likely see uneven tire wear due to that slack in the system.
Just as the top two indicate, that slack will cause uneven alignment. Without proper alignment, your car will not track straight.
With such slack, you’ll also feel it in the steering wheel. Your cornering won’t be as precise.
Noise and/or Vibration
The bad tie rod might also be clanking and vibrating through the steering wheel.

The Car Bibles Tie Rod Glossary
Welcome to Bible school!
A shock is a hydraulic or pneumatic compression absorber that doesn’t feature an external spring.
A strut is a hydraulic or pneumatic compression absorber that features an external spring and is used as a pivot point.
A double-wishbone suspension uses two control arms, one at the top and the other at the bottom. They connect to the wheel knuckle and provide increased possibility of tuning.
Lower Control Arm
The lower control arm allows the suspension to move up and down in a stable fashion.
A ball joint is a spherical bearing that connects the steering knuckle to the control arms.
A sway bar, or anti-torison bar, connects the two sides of the car via the top of the suspension. This increases the car’s torsional rigidity.
Car Bibles answers all your burning questions.
Q: How Much Does It Cost To Replace a Tie Rod?
A: If you do it yourself, you’re looking at anywhere between $40-$150, depending on on the car. If you have a certified mechanic, take on another $100-$200 for labor.
Q: Is It Dangerous To Drive With Bad Tie Rods?
A: As our friends in Minnesota like to say, “You betcha.” At best, it reduces your ability to steer properly. At worst, it can separate the wheel from the rest of the car. Now, do you want that?
Q: Can I Replace Tie Rods Myself?
A: You can! Just make sure you don’t need your car the following day. Any time when you’re working on a part that ensures safe travel, give yourself the proper time to do it right.
