Tie rod connects the steering rack to the steering knuckle, making them an essential component of your vehicle’s steering system. It is tie rods that not only help you steer, but they also allow you to turn your vehicle. The steering of your vehicle would be impossible without tie rods.
The tie rods are worn and damaged because they are used every time you steer your vehicle. Damage to a tie rod can also be caused by road hazards such as potholes and accidents. Damaged and failing tie rods can have mild to severe effects.
Define Tie Rod
Normally, you’ll find tie rods on your car. A tie rod connects your steering wheel and gear to your tires. When you turn the wheel, the tie rod moves and the tires move with it. Ball-in-socket motions in tie rods allow the wheels on your car to move smoothly up and down, side to side, as well as front and rear. When trying to move bellows, tie rod motions accomplish the same motion.
Each ball joint and tie rod end is part of the front suspension and steering system of your car. These components are located between the front wheels.
Functions of Tie Rod
The tie rod plays an important role in the steering system of a vehicle. With a ball socket on one end, the rod is used to connect or tie the steering gear to the wheel. As the wheel turns or moves up and down with the road surface, this ball socket allows for controlled movement. A popular steering design usually involves a tie rod inside the steering gear and an outer tie rod outside the wheel assembly. To adjust the alignment of a car’s front wheels, the thread connecting the inner and outer tie rods is adjustable.
The steering linkages play a crucial role in your car’s mechanism. Among its important functions is to transfer driving movements from the steering gear to the wheels, which then direct the movement of the vehicle. Because these components directly affect the direction of the vehicle, it is vital that they work properly. Therefore, if any signs of steering linkage failure are observed, don’t ignore them. Have it repaired as soon as possible.
Parts of Tie Rod
Tie rods are cylindrical structures with two sections made of high-strength steel. Tie rod ends consist of an inner and outer section, the outer section being known as the tie rod end.
Tie rod ends commonly come in 7 piece sets that contain all the parts and components needed to assemble the tie rod.
The sliding ring seal is usually a rubber case or rubber cap that acts as a sliding seal, which facilitates an adequate lifetime at high pressures by increasing contact force at the sealing surface.
In the socket body, the spherical bearing resides along with the preload spring and is protected from damage from impacts. The preload spring and bearing are kept in the correct position by the spherical bearings as they are intended.
The fatigue strength they provide is also enhanced through proper alignment, which helps prevent fretting. As a result, transverse girders are less subjected to bending stress.
To enable the wheels to steer, as well as pivot so that the suspension can move up and down, the ball stud and tightening nut are attached to the suspension and steering components.
Whenever the wheel is rotated, the tie rods must rotate as well. This rotation can be performed with precision and control thanks to spherical bearings on rod ends.
In addition to acting as a seal shield, the closure cap protects the spring from rocks and debris.
It is the preload of the spring that forces the tire down and makes the suspension work.
A large spring preload keeps the tires from rolling down on big bumps at speed, allowing for a more controlled ride. As the spring preload increases, tire contract pressure increases, contributing to improved road traction.
Workflow of Tie Rod
Your vehicle’s steering is dependent on tie rods. Tie rods connect the steering column to the steering arm of your car as suggested by their names. Your steering wheel is connected to the steering arm. Rack-and-pinion steering and or mechanical steering are the two types of steering systems.
In your automobile, the steering linkage is part of the suspension system that connects the front wheels. This linkage connects the gearbox’s transmission to the tie rod’s front wheels. Tie rods are further joined by a ball joint-like socket, known as tie rod ends, which allows the linkage to work freely, so that vehicle motion is not interfered with as the wheels move on the road.
Rack-and-Pinion Steering System
The rack-and-pinion steering system is simple. When you are turning your steering wheel, you will cause your pinion gear, which is attached to your steering shaft, to roll along with the steering rack. When you turn your wheel, the steering rack attached to both front wheels will move accordingly. Tie rods transmit steering rack force to the steering arm, which moves the wheel.
Mechanical Steering System
Mechanical steering systems are a little more complex than rack-and-pinion systems. These systems typically have a gearbox attached. The steering shaft activates several gears that control the pitman’s arm when you turn your wheel. When you steer, the pitman’s arm moves the steering rack. The steering rack in a rack-and-pinion system is connected from the tie rods to the steering arms. It will make a connection between the steering systems to the wheels.
These two systems may look complex but contain very simple & important part, which is known as a tie rod. The tie rod plays an important role in your steering system & without it; the whole steering system will collapse. The steering system & steering arm is connected by the tie rod. There is an outer tie rod end that can be adjusted. As a result, you can replace the tie rod’s length to fix your vehicle’s alignment. The simple tie rods are very crucial for your wheel’s movement when you steer for making a turn.
Types of Tie Rod
In a single-tied expansion joint, the tie rods prevent axial movement and hold the ends constantly. It is possible for lateral movement to occur in the tie rod.
There are many applications for which universal-tied expansion joints make sense. Each element tilts to accommodate lateral offsets while creating a low lateral spring rate. These joints are widely used across many industries.
Universal-Tied with limit Rod
Combined with limit rods, another expansion joint accessory, universal-tied rods can extend the length of the expansion joint while still accommodating axial compression and angular motion.
Signs of Bad Tie Rod
Front end Alignment error
You steer your vehicle with tie rods, which ensure it tracks straight. The front end of your vehicle can become misaligned for a variety of reasons, including a worn tie rod, which can become loose. You should consult a qualified technician if your vehicle is having trouble handling.
Too much Noise
When turning at low speeds, you may hear any clanking or knocking sounds from the front of the vehicle due to worn tie rods. The new noises you’re hearing can be caused by loose tie rods that rattle around at the joints and links. Moreover, if the boot that protects the tie rod joint becomes damaged, dirt and debris can get inside the joint and cause the steering wheel to grind. Check in with a qualified technician if you hear new sounds coming from the front of your vehicle.
Vibration Issue in Steering Wheel
A loose or damaged tie rod can lead to steering problems because the tie rod links the steering wheel to the front wheels. The steering wheel may shake or vibrate, as well as be loose or play excessively. As you accelerate or turn, the vibration usually gets worse. As soon as you notice steering problems, take your vehicle to a qualified mechanic.
Uneven Tire Wear
Tires can wear unevenly or excessively if their tie rods are damaged. Examine your tires visually; if one side displays excessive wear and the other side doesn’t, it could be a sign of a failing tie rod. Tie rods that are working properly are indicated by even tire wear. Make an appointment with a qualified technician if you have concerns about uneven tire wear.
Hit a curb or Pothole
Over time, your tie rods can inevitably wear out from normal wear and tear, but a severe strike on a pothole or curb can do irreparable damage. If your car develops a new shake in the steering wheel, noises when you turn or other symptoms after hitting something. With a worn tie rod, you may still be able to drive, but if it fails completely, you will lose steering control and will need a tow home or to our service center.
Loose Wheel Feeling
You can perform an easy and quick test of your vehicle’s tie rods right in your driveway if you’re not sure whether your tie rods are bad and you have a little time and some tools. It just takes a jack to fix the tie rod of that steering system.
You can grab the front tire with your hands by lifting the front end of your car.
- Shake the wheel between 3 and 9 o’clock with your hands.
- Shake the wheel by placing your hands at 6 and 12 o’clock.
Repeat this procedure on both front wheels. All things being equal, you should only be able to rotate the wheels. You should replace your tie rods or other related components if one or both wheels shift a little bit or make a clicking sound.
How to replace Outer Tie Rod?
Your vehicle’s wheels should be chocked. You can park your vehicle on a flat, dry surface & make sure you wear safety goggles and gloves. You can easily access the car if you lift it, place it on jack stands, and remove the wheels.
Inspect the Tie Rod
On the steering knuckle, next to the tire, is the ball with stud and locking nut. It is recommended to spray penetrating oil on the jam nut and its threads as well as the top castle nut, since they are often heavily corroded. It is connected to the steering knuckle on one side by a castle nut and cotter pin in order to prevent it from slipping. Another side of the tie rod is threaded, and connects to either a center link, drag link, or adjustment sleeve. These components are still found in more traditional steering systems, and this feature still exists in some trucks.
Remove & Separate Tie Rod’s Stud Nut
There is a tapered stud and nut on each side of the tie rod that connects it to the steering knuckle of the car. There are sometimes Nylock nuts in place of this castle-style nut with a cotter pin. Remove the cotter pin from a castle nut.
These can often be corroded and difficult to remove. In order to ensure proper sealing of the nut, flood it with penetrating oil. The next step is to remove the nut. To dislodge the tapered stud from its bore, you will need a tie rod separator. The tie rod must be inserted between the knuckle and the tie rod, and it must be hammered until it drops and separates. Many tie rods are very stubborn, so this process can take time.
Remove the Jam Nut
Hold the inner tie rod steady with a wrench and break the jam nut loose after soaking the jam nut with penetrant. Avoid using a hammer to prevent damage or warping. To remove the lock nut at the other end, move to the other end. There are some outer tie rods that use a castle nut with a cotter pin, which differs from the information provided in this video. Remove the castle nut completely if this is the case for your vehicle. Straighten the pin and pull it out with needle nose pliers.
Remove Completely from Steering Knuckle
Lift the outer tie rod from the steering knuckle using a specialized tool for removing tie rod ends. When removing the old tie rod end from the inner tie rod, count the number of turns, or mark the position before turning. To ensure the replacement part is compatible with the steering system, measure the length, taper, and thread length of the new and old outer tie rods.
New Outer Tie Rod Installation
Count the turns or stop at the mark you recorded earlier when connecting the new tie rod end to the inner tie rod. Be sure to insert the taper all the way into the steering knuckle. When the stud starts to spin, tighten it using your fingers or a light wrench. It is not recommended to use an impact wrench as it will cause unnecessary spinning, which could ruin the new part.
You should tighten the lock nut to the manufacturer’s recommended torque using a ratchet. As soon as you have tightened the castle nut, you should install the cotter pin. Pull the pin through and bend it in combination with needle nose pliers to ensure it is positioned securely around the nut.
Check your car’s alignment
Make sure the other suspension parts are in good working order before reinstalling the wheel. Take the vehicle to an alignment after torqueing the wheel on the ground and going on a short road trip. Reset the steering angle sensor whenever the front end of a vehicle is aligned.
How to Buy the best Tie Rod End?
It is generally more difficult to carry heavier units and even more difficult to install them in vehicles. The front portion of your vehicle will need to be disassembled in order to install tie rod ends. When installing a heavy unit on the vehicle, it can be difficult to hold everything in place at the same time.

How much you need to spend for tie rod replacement?
Tie rod replacements are not an expensive repair even though front end work becomes quite frequent as a vehicle ages. The cost of most tie rods is between $40 and $120, with inner tie rods being more expensive than outer tie rods. It is possible on some cars to buy a tie rod in which inner and outer tie rods are sold together. Depending on whether the inner or outer tie rod needs to be replaced, labor costs will range from $45 to $85 for a tie rod replacement. Wheel alignment will be required to replace the tie rods, adding to the final bill $80 to $100.
Is it right to drive with faulty tie rod?
In the absence of a regular oil change and basic maintenance, your state inspection surely will detect a worn tie rod. Getting the tie rod repaired as soon as possible is best, as a tow will be necessary if the tie rod breaks. It is important to find a good mechanic who specializes in front end and steering repairs, and to schedule an appointment. It should take less than one day for your car to be repaired, since these are fairly common repairs.
Is it ok to replace tire rod at home?
The factory service manual specifies a test protocol for determining if a tie rod end is worn out. Only one tie rod end needs to be replaced if it turns out only one is worn out, and the rest can be left alone. As a result, most mechanics replace tie rod ends as a pair if one end is obvious unserviceable. Although such pairs of replacements are technically not required, economics dictate that if the mechanic is already there, it is less expensive in the long run to replace both, particularly because wheel alignments must be performed after every replacement.
Last but not least, alignment tolerances are extremely small these days. It is literally impossible to align the car to factory settings if there is any wear at all on the nonreplicable tie rod end.
