All about car axles: What they are and how they work

Vroom, vroom! Every car enthusiasts and non-car enthusiast love that sound, whether it’s a Ferrari or Mustang or any sort of exclusive car. Car enthusiasts will easily know that it’s the engine that’s making this noise, but non-car enthusiasts might think it’s probably some other parts of the car that are making this noise, as they have little to no knowledge about the car’s interior mechanical parts and how they work.

Similar to that situation, many people might think that it’s the steering wheel that’s rotating the car wheels all by itself, but that’s not true and that is why we are here today to help you understand all about what are axles, how many types of axles are there and what is its purpose.

There are certain things that you should know about car axles in order to keep your vehicle running smoothly. This guide will teach you everything you need to know about car axles, from their history to how they work. Whether your car has standard axles or something more exotic, this guide will help you maintain and operate them properly.

In fact, the axle is one of the most important components in a car, and its ability to transfer power from the engine to the wheels is crucial for transportation. Here’s everything you need to know about car axles, from their construction to how they work. Well, to start off with,

What are Car axles?

It is a type of rod that is linked to the car’s two wheels and conveys the car engine’s power to move around the wheels left and right. The axles are one of the prime parts of a car and hold valuable powers within it. They can bear so much weight that they can withstand the mass of the car including the passengers, and their belonging while also handling the force of accelerating and braking.

The axles are reinforced by the bearings that are adjusted in the central parts of the wheels. They can be adjusted in two different ways:

  1. The axle is fixed to the car wheels and will rotate left or right according to the driver’s movements.
  2. The axle is fixed on the vehicle’s structure so that the wheels will rotate left or right according to the axle’s movement.

Now that we have discussed what is an axle and what is its purpose, let us now dive into the various categories of axles present and used in different types of cars. There are three types of axles, and they are as follows:

Types of car axles:

Now that we have discussed what is an axle and what is its purpose, let us now dive into the various categories of axles present and used in different types of cars. Basically, there are three types of axles and they are as follows:

  • Front Axle

You can already guess according to its name where it is located inside the car. They are created using mainly carbon steel and sometimes nickel steel so that they can be as solid as possible. It has four fragments to it.

  • The track rod
  • The beam
  • The swivel
  • Stub axle

 Its main responsibility is to help the car while steering and to feel and process the disturbance felt from the rough rocky and potholes on the road. There are 2 types of front axles. One of them is the Live Front Axle, which assists in power delivered to the front wheels from the gearbox. The other one is Dead Front Axle, which prevents the wheels from rotating on their own and stays in one specific position.

  • Stub Axle

This is the most confusing type of axle created by human beings. They are located in front of the front wheels and they are attached to the front axle. They are very confusing as the left and right wheels are not connected using the same connection so theoretically speaking, they are two different axles. Then again, the basic rule of counting the number of axles present is done sideways, so that would mean this theory is pointless.

Now one might ask, if it’s so confusing, where is it used? And the answer to that question would be on non-driven wheels in a car and kingpins usually attach these axles to their front axles.

  • Rear Axle

They live in nature so that means they rotate with the car’s wheels but not in all cases, just in majority of cases. They are mainly tasked to supply power to the driving wheels. However, they do not come in one piece as they are divided into two-piece, each being called half shafts that are joined together by the differential. Like peas in a bag, they also come in varieties, which are fixated on their ability to support and their mounting system such as:

  • Semi-Floating Axle- This type of axle creates a joint between the wheels all the way to the flange bearing on the axle’s exterior shift and makes sure to tightly clutch it. This type of axle is divided into 2 types. One of them goes inside the axle casing whereas the other one reinforces the axle shaft. Possessing 2 bearings would mean that the semi-floating axle has to be bigger compared to the others to create the same amount of tortuosity. Hence, are used in average sized trucks, SUVs, and several types of cars.
  • Full- Floating Axle- You can already understand how it works according to its name as due to its bearings, it is fixed to be floating in a specific location to help maintain its position. They are designed mainly for vehicles that can handle harsh road driving and a heavy amount of loads on them such as heavy-duty trucks, 4 wheel drive cars and average sized towing trucks as they can convey driving tortuosity. These axles are so strong that they can handle the heavy weight of these vehicles hence making them quite durable. Semi-floating axles are better compared to full-floating axles as they can convey the torques and still weighing less.
  • Three Quarter Floating Axle- While the name is big and complicated, only three quarters of its mass is floating. This type of axle is complex yet well-grounded when compared to semi-floating axle. This type of axle helps to maintain the wheel alignment and also improves in handling.

If you think that’s all there was when it comes to axles, you are going to have to wait for quite some time as there are more types of axles as we progress forward. So, get back on your feet and let us continue.

Axles are further again categorized into 2 different sections, which we will be learning about now.

  • Drive Axle

The drive axle starts from the differential and goes all the way up to the tires. They are placed on either front two or both rear wheels, which are essential, as they need to control both the front and rear axles. They are enclosed within axle housing, which provides more safety and allows it to utilize it much more effectively.

  • Dead Axle

The dead axle AKA lazy axle functions quite the opposite compared to the drive axle. It is a free rotating axle, which isn’t attached to an engine and has no part in the drivetrain. To understand using even simpler words, the rear-axle that is attached to the front wheel drive is basically known as the dead axle. Dead axles don’t have much use but they do, however, bear the weight of the vehicles; for example, RVs and trucks.

How car axles work?

Car axles are the primary means by which a car moves. They are made of three parts: the hub, the axle shaft, and the wheel. The hub is located in the engine compartment and is connected to the axle shaft. The axle shaft goes through the car’s frame and connects to the wheel. The wheel turns around the axle shaft, which in turn moves the car forward or backward.

What affects axle performance?

A basic understanding of axle performance is essential to maintaining optimal vehicle performance. Factors that affect axle performance include the weight and size of the load, the type of axle, the tire size and inflation pressure, and the alignment of the axle. The following are some common factors that can affect axles:

  1. The weight and size of the load: Larger loads will require more torque to move them, while lighter loads will require less torque.
  2. The type of axle: A rear-wheel-drive has more torque required to turn it than a front-wheel-drive because there is more weight on the rear wheels. An all-terrain/off-road axle requires more torque to move through tough terrain than an urban or street-oriented axle.

What should be car axles wheel alignment and axle alignment?

When it comes to car axles and axle alignment, there are a few things that you should keep in mind. First and foremost, your car’s axles need to be adjusted so that the wheels are aligned with the axle. This ensures proper suspension operation and prevents unnecessary wear and tear on your vehicle’s components.

Additionally, properly aligning your car’s wheels can help improve handling performance. Finally, aligning your car’s axles can also prevent wobbling or other abnormal motions. If you have any questions about car axles wheel alignment or axle alignment, don’t hesitate to contact a professional mechanic.

What causes car axle problems?

Car axles are a critical component of a car, and their failure can cause major problems. Some of the most common reasons for axle problems include worn or broken bearings, loose joints, and bent shafts. In order to prevent these issues from occurring, it is important to keep your car’s axles in good condition.

What causes broken bearings in car axles?

Broken bearings in car axles are a common problem that can lead to decreased axle performance and even failure. There are many factors that can contribute to the occurrence of broken bearings, but the most common causes are accidental impact, wear and tear, and abuse. The causes of broken bearings can be many and varied, but a few key factors are often involved.

1) Improperly maintained machines: Poorly maintained machinery is a leading cause of bearing failure. Not only do neglectful operators put unnecessary stress on the machine, but also incorrect maintenance can have devastating consequences for the bearings within it. For example, dirty or greasy surfaces can cause friction that results in wear and tear on the bearings. In extreme cases, this type of damage can lead to the complete failure of the machine’s bearings.

2) Lack of lubrication: Bearing lubrication is critical for its proper function.

3)The accidental impact is the most frequent cause of bearings breaking, as objects inside the car can hit the axle shaft at high speeds. Worn or abused axles can also cause broken bearings, as metal on-metal contact can create heat and pressure that causes the bearing to fail.

What causes loose joints in car axles?

Loose joints in car axles are common and can lead to problems such as vibration, noise, and poor suspension performance. A few factors can cause loose joints in car axles, but the most common is age. As the axle joint loosens, it becomes easier for particles to accumulate and create friction.

This can lead to wear on the joint and eventually failure. Another major contributor to axle joint looseness is improper maintenance. If the axle is not lubricated or properly tightened after repairs, it will continue to suffer from accumulated debris and wear.

What causes bent shaft in car axles?

There are a few common causes of bent shafts in car axles. One of the most common is when the axle is misaligned and undergoes excessive twisting. Bent shafts can also be caused by over-torquing the axle, which can cause the metal to fail prematurely. In cases like these, it may be necessary to replace the entire axle assembly.

How to move a car with a broken axle?

In this section, we will teach you how to move a car with a broken axle. We will use the method of a car jack to lift the car off the ground, and then we will use a tow truck to pull the car out of the ditch.

Step 1: Get a car jack:

If your car has a broken axle, you’ll need a car jack to raise it off the ground. You can use a car jack, but you will need to use a car jack that is designed to lift a car off of the ground. A car jack should be able to lift at least 20,000 pounds. If you don’t have one, you can buy a car jack online.

Step 2: Lift the car:

You can use the car jack to lift the car off of the ground. To do this, place the car jack under the car, and then push down on the handle. This will cause the car jack to raise the car off of the ground.

Step 3: Put the car on the ground:

Now you have to move the car from the raised position to the ground. To do this, place the car on the ground. Then, use the handles of the car jack to lower the car.

Step 4: Attach tow hook:

Attach the tow hook to the back of the tow truck.

Step 5: Connect the tow hook to the car:

Connect the tow hook to the car. When the car is lifted off of the ground, it will be easier to move the car. To do this, you will need to use a tow truck. Ask a friend or neighbor if they have a tow truck. If not, you can rent a tow truck.

Step 6: Pull the car out of the ditch:

Pull the car out of the ditch.

Maintenance tips for your car axle:

Regular maintenance on your car’s axle will keep it running smoothly and help prevent serious repairs. Here are some tips to help you keep your axle in top condition:

  1. Check the fluid level. It’s important to check the fluid level every time you do a tune-up or repair. If it drops below the minimum line, add new fluid. Change the oil and filter regularly
  2. You should change your car’s oil and filter every 3,000 miles. Checking and changing these components helps ensure your axle runs smoothly and prevents costly repairs. Inspect bolts for tightness
  3. Bolts that are too loose can cause your axle to wobble or shake when driving. Tighten all bolts accordingly using a torque wrench to avoid future problems. Check alignment regularly
  4. Alignment is key for keeping your car’s axle running smoothly.


In conclusion, we have learned today the different types of axles present and their function. Different types of axles differ based on the vehicle they will be used for. A lot of people will tend to know about the different types of axles, wheels, and engines, but I think it’s better to know what those different types of axles, wheels, and engines do instead of just knowing their names.

Even though axles are made to withstand extreme weight, they can still have problems within them and break down due to various reasons. Looks like you have most of the answers now regarding axles, and I hope my article has helped you tremendously.

how many axles does a car need?

You might think it’s 2 since one for front wheels and one for the rear wheels, whilst some might think it’s 4 as in one per wheel front and rear. However, the correct answer would be that it depends on the type of vehicle as not all cars are the same and there are a lot of different types of cars and trucks and buses, and many more. A lot of car owners would like to customize their own axles for their own benefit.
At times, it depends on the car’s interior structure which is its suspension system which contains springs, some connections, and a few more other components. In some cases, axles have to support the weight of both the vehicle and the passenger’s belongings on it. Well, to finally answer your question, a normal car has 2 axles present in it, front and rear.

can cv axle stop car from moving?

That’s a question that’s been on many drivers’ minds and it has some surprising answers. In short, the answer is that it depends on the type of CV axle and the make and model of the car.
One common type of CV axle is found in cars and trucks. This type of axle uses a hub and disk system to allow the vehicle to rotate around its center point. When the disk becomes jammed or broken, it can cause the car to lose traction and eventually come to a stop.

Another type of axle is found in SUVs and other large vehicles. These axles usually use an articulated joint between the drive shaft and differential, which allows for more flexibility in terms of the motion. While this type of axle can also become jammed or broken, it’s much less likely to cause a problem with a car.

can you drive a car with a broken axle?

If the axle is only bent or twisted, then it is possible to drive the car until it is fixed. However, if the axle is completely broken, then you will need to get a new one.
When your axle breaks, your car’s suspension will go out of balance and it will become increasingly difficult to drive. If you are driving on an uneven surface or in rain or snow, your car may even flip over. In addition, if your wheel rim is damaged by the broken axle, you may be liable for damage to both your vehicle and your property.

how to know if car axle is broken?

If you are driving your car and notice that one or more of the car’s axles seem to be wobbling, it may be time to take it to a mechanic for inspection. Checking for broken axles is one way of knowing if your car is in danger of becoming unstable. Checking for broken axles can be done by looking at the outside of the axle, as well as checking the wheel nut for looseness or damage. Broken axles can also cause your car to lose power and may even require replacement.
So if you notice any signs that one or more of your car’s axles may be broken, it is important to take action right away.

What is the difference between a CV joint and a CV axle?

A CV joint is a type of joint that connects the steering shaft to the wheel. It is located in the center of the steering column. A CV axle is a type of axle that connects the rear wheels to the car. It is located in the center of the rear end of the car.
