Different Types Of Tie Rod End

There are two types of tie rod end: inner and outer. Both types are essential in an automobile for the steering system to perform the basic functioning. So when something bad happens, there is the chance that your car has also bad inner tie rod symptoms and outer tie rod end symptoms. Let’s get to know a bit about these:

1. Inner Tie Rod

An inner tie rod can be found at the center line of the vehicle.  It consists of the first turn point that makes the vehicle rotate in a particular direction. It is more like a ball socket that spins accordingly.

2. Outer Tie Rod

As the inner tie rod includes the initial pivot point, the outer tie rod adds up the final pivot point. Further from the center of the vehicle, it is located at a distance from the inner rod and hence named as an ‘outer tie rod.’ The rod makes the vehicle rotate once the inner rod performs its part using the first turn point that gets transferred to the final turn point.

Most of the cases, when your car faces symptoms of bad tie rods, it may be because of the inner tie rod, outer tie rod or both of them.

Signs Of Tie Rod Problems

The constant use of the steering wheel makes the tie rod wear off after a few years. During its lifecycle, an automobile faces different surfaces or roads such as the paved and the rough ones. The more drive hours a car goes through, the more it is likely to create fatigue to the tie rod. As a result, the rod does not work as expected. Here are the symptoms of a broken tie rod.

1. Steering Wheel Shakes or Loose

The tie rod is designed to make sure everything is solid in the suspension. So when it wears out, it tends to bounce or have some play in the tie rod end. The result is the vibration that you can notice in the steering wheel. Usually, the tie rod end will start to vibrate at speeds as low as 20 mph and gradually increase as the vehicle accelerates. 

In some other cases, you will see the tire, wheel combination is out of balance or the suspension component that is broken. They are the symptoms of bad tie rods. The only solution in this situation is to identify the symptoms if a tie rod needs replacement and take it to the nearby auto shop.

2. Unfamiliar Noise

Tie rod end features a lubricated ball stud and bearing that’s sealed within a rubber boot. So when the boot is damaged or cracked, the lubricant which allows the bearing to move smoothly can leak and cause the bearing to grind. The sign is the unusual sound from the car, the squeaking noises especially when you turn the car on.

3. Front End Alignment Is Off

As we mentioned above, the function of the tie rod end is keeping things solid on the front end of your vehicle. The tie rod together with the wheels, tires, stabilizer bars, struts affect directly to the vehicle’s alignment. So when you have the bad tie rod, it will become loose and cause the front end of the vehicle to fall out of alignment. When you drive your car, you can easily feel it. 

4. Uneven And Excessive Tire Wear

If you take your car to the mechanic usually, the tire wears evenly. So if you have trouble with the tire, it means that one in the set wears faster than the others. And the reason behind it could be the bad tie rod. 

Actually, you can easily complete a visual inspection of your tires to determine if they are wearing unevenly or not. You just need to stand in front of your vehicle and look at the edges of the inside and outside of the tire. If they appear to be evenly worn, this is a good sign that your tie rod end is functioning correctly. But if the tire is worn excessively on the inner or outer portion of your tire, this is one of the symptoms of bad tie rods and it should be inspected.

What Causes Tie Rod Ends To Go Bad?

Most of the tie rods wear out over time. But there are also exceptions for the older cars and a few modern trucks have tie rod ends with grease fighting that need to be regularly maintained. Besides, if the boot is damaged or cracked, the grease can leak from there. As a result, the tie rod wears out. 

Knowing what leads to the symptoms of bad tie rods is important, but it is more crucial to fix the worn out tie rod right after you find that signal. So whenever you notice your tie rods are causing your car to underperform, don’t hesitate and bring your car to an experienced mechanic.
