What Is A Tie Rod? Its Functions, Diagram, And How its Works

Steering systems come in a variety of forms, including rack and pinion steering and recirculating ball steering, but they all have one thing in common that makes them work well: the tie rod end.

Each front wheel has tie rods that connect the steering gear to the steering knuckle and are engaged each time you turn your steering wheel. Simply explained, you cannot steer a car without tie rods.

Well, in this reading, we’ll explore what a car tie rod is, its functions, diagram, and how it works. We’ll also learn its signs of failure.

Let’s get started!

What Is A Tie Rod?

A tie rod (also called a hanger rod if vertical) is a narrow structural unit used as a tie that can only handle tensile loads in most situations. It is any rod or bar-shaped structural element used to keep two parts of a vehicle together.

The tie rod end is a component that all steering systems have that allows them to steer properly, despite the fact that there are many different types of steering systems, including rack and pinion steering and recirculating ball steering.

Tie rods are positioned on each front wheel and connect the steering gear to the steering knuckle when you turn the steering wheel. Simply put, without tie rods, you can’t steer your car. A car has two tie rod ends, one inner and one outer, normally presented on each side of the car.

For a four-tie rod ends, two on each side. Although tie rod ends are typically permanently lubricated, some, especially aftermarket ones, may contain Zerk fittings for re-greasing.

Function Of A Tie Rod

The functions of a tie rod is to connect the steering rack to the steering knuckle. One of its functions is to help move your wheels when you steer and make turning possible in your car. The tie rod in a car is a bar-shaped strutural member designed to prevent the separation of two parts.

Construction Of A Tie Rod

A tie rod is a thin, two-sectioned, cylindrical construction composed of high-strength steel.

Together, the inner and outer tie rod ends provide you with the best possible wheel control. While the outer tie rod attaches to the steering knuckle, the inner tie rod, which is composed of an inline ball joint, links to the steering rack.

How A Tie Rod Works

Tie rods are an essential component of the steering system in your car. A tie rod connects the steering rack of your car to the steering arm, as the name implies. The steering arm is attached to the wheel.

Steering systems come in two varieties: recirculating ball or mechanical steering and rack-and-pinion steering.

The operation of a rack-and-pinion steering system is simple to understand. When you turn the steering wheel, a pinion gear attached to your steering shaft moves along the steering rack.

The steering rack will move in reaction to wheel rotation because it is connected to both of the front wheels.

The tie rods are responsible for transferring force from the steering rack to the steering arm and wheel movement.

Further, the recirculating ball or mechanical steering system is a little more intricate than the rack-and-pinion system. The gearbox is part of the mechanical system.

When you turn the wheel, your steering shaft engages multiple gears that regulate the pitman arm. Depending on how you steer, the pitman arm moves the steering rack.

The steering rack, like the rack-and-pinion system, is connected to the tie rods, which are then connected to the steering arms. Your steering system is connected to your wheels via tie rods.

Signs Of A Bad Tie Rod

Tie rods are prone to wear and damage since you use them each time you steer your car. In addition to normal wear and tear, driving hazards such as potholes, poor road conditions, and accidents can also result in tie rod failure or damage.

It is essential that you schedule an appointment with your mechanic for an accurate diagnosis if you encounter any of the following symptoms:

Viberating Or A Loose Steering Wheel

Observe the sensation of your steering wheel. A loose tie rod end could be the source of excessive play, vibration, or shaking.

Front-End Misalignment

Worn tie rods may be the cause of alignment issues in the front end. You should bring your car to your mechanic if something seems off because broken tie rods are not the only thing that can cause front-end misalignment.

Uneven Tire Wear

Check the outer and inside edges; if one side of the tires is heavily worn while the other is barely worn, there may be a problem with the tie rods.

Strange Sounds

Worn tie rods may make knocking noises or other odd noises when turning. A visit to your technician will validate the diagnosis and perform the appropriate repair.

FAQs

How long do tie rods last?

Tie rods can last for several years. It’s possible that you won’t ever need to replace your tie rods. Your driving environment has a big impact on how long tie rods last.

Can you drive with a damaged tie rod?

Driving with a damaged tie rod can significantly affect how your car handles and steers. You might discover that your steering veers, giving you little control over turning the car in the desired direction.

Do not hesitate to schedule a technician’s appointment for the appropriate repair if you think you may have a tie rod issue.

What would happen if a tie rod broke?

If a tie rod fails, the consequences might be as little as early tire wear or as serious as losing all control of your car. In just a few miles, a malfunctioning tie rod might deteriorate further.
