CV Axle Not Seated Properly Symptoms: How To Fix Them?

How many CV axle not seated properly symptoms do you know?

This is a difficult question as knowledge about cars and car parts is very much, and not everyone has insights in them.

Some people will even not know which part of the car the CV axle is in, let alone when it’s not correctly placed.

That’s why you shouldn’t skip this article. The next sections will show you the bad axle symptoms you can check to maintain the car’s best performance and ensure safety on the road. Let’s get started!

CV Axle: What To Know

CV Axle

What Is It?

The rubber boots and bearings that make up the CV axle give bearings a range of motion and enable the transmission to drive a car’s wheels.

The constant velocity axles, or CV axles, are used when a vehicle’s wheels move continuously rather than only rolling.

This calls for flexibility so that the transmission can transmit its driving force to the wheels.

How Does It Work?

The hub is connected to the transmission by the constant velocity axle, which turns the vehicle’s wheels. FWD or AWD cars with independent suspensions employ CV axles in the front.

A movable tripod housing makes up the inner CV joint, which allows the axle to expand or shrink. Three rollers are housed inside a carrier with needle bearings, and each roller has a modest swing degree.

The outer CV joint needs to be able to flex a lot close to the steering axis even though it does not telescope. The outer joints comprise an exterior race or housing, a carrier, and an inner bearing race.

The real benefit of a CV axle is that it has input and output shafts that rotate at the same speed and provide a great degree of articulation.

This is perfect for the front wheels because they steer and move sideways and up and down with the suspension.

CV Axle Not Seated Properly Symptoms: How Can You Know

The Symptoms When CV Axle Not Seated Properly  

How can you know that the CV axle not seated into the transmission? You will notice a strange noise, vibrations in suspension, harder car handling, presence of gap, or knocking sound when this part is out of place. 

Strange Noise 

The first one in the CV axle not seated into transmission symptoms is strange noises.

Weird sounds underneath your automobile can signal a loose axle in various ways. When moving in reverse, for example, it could generate a repetitive, louder clunking sound.

Sounds that are loudly popping or clicking might be recognized right away. As the automobile turns sharper or faster, the noise may get louder or more noticeable.

Vibrations In Suspension

Vibrations in suspension alert you about bad inner cv axle symptoms.

Vibration in the suspension frequently gets worse as you accelerate. Remember that any misalignment between the axle shaft and CV axle will influence your CV axle’s balance during wheel rotation.

The shaft and suspension system will vibrate significantly while the automobile is driving as a result. An incorrectly seated axle will suffer damage that could be a factor in the vibrations.

Also, remember to lubricate the suspension periodically to maintain its best.

Harder Car Handling

The next one on our list of bad inner CV joint symptoms is an issue with car handling.

When the CV axle is not properly positioned, you can also notice a detrimental effect on your car’s handling and other characteristics.

The impact of this issue includes decreased aerodynamic efficiency and difficulties steering when turning or rounding bends.

Many reasons lead to this situation, and it can originate from other parts, like the steering wheel. However, when facing this problem, ensure your CV axle is not having problems.

Presence Of Gap

When you notice the gap between the CV axle and transmission, it’s time to check this part more carefully.

The gearbox that links to the axle and the back of the external CV joint has a few inches of space between them. This shows that the axle is not correctly seated as it should be.

Knocking Sound

Similar to what was stated before, a knocking noise you hear while driving could come from the faulty CV axle. Even if the half-shafts are not to blame, unexpected banging rarely has a trivial cause.

This is one of the most popular bent CV axle symptoms. It would be better to drive your car to the service center and get help from professional mechanics.

How To Adjust The CV Axle Properly

Ways Adjust The CV Axle

Can a bad CV axle cause a loss of power? The answer is yes!

Let’s learn how to push in CV axle step-by-step right now!

Step 1: Remove The Strut

When your CV axle not fully seated, remove the strut and axle nut first. It is easy to accomplish and doesn’t require wheel alignment.

Step 2: Rotate It

A small rotation might have a big impact on the situation. The shaft and transmission splines may be aligned up rather than sitting next to one another.

Grease should be applied when installing an axle for the first time to maintain its alignment. The driver’s axle should snap into place without needing a hammer.

After using oil in the center of the lock ring, push the axle in firmly. If it still doesn’t fit to align the threads, try twisting it slightly as you push it in.

Step 3: Arrange The Axle Parallel

If the axle is at any angle when entering the splines, it won’t fit in. To get your car moving, elevate the control arm using the jack.

You can also include a piece of wood to support the axle by placing it on the lower control arm so that it has a clear route to enter the hole. The inner axle’s end should then be easily inserted after that.

Step 4: Give It A Decent Tug

It could be challenging to remove the axle from the transmission. This is because when it locks in place, removal is more difficult. When unsure if it is seated, a good tug will allow you to determine whether it is fully in.

Step 5: You Can Ask For Help

Check the alignment of your splines. While the car is in neutral, spin the axle to check whether you can feel anything catching in the differential.

If so, hold it in place with the help of a friend while you press the exterior of the axle into the wheel hub assembly.

It would help if you did it until all CV joints were compact. After that, use a hammer to tap it in gently.

FAQs 

How To Seat A CV Axle Transmission?

Can a bad CV joint affect transmission? Certainly!

As mentioned above, you can learn how to seat it with our five-step guidelines:

  • Remove the strut
  • Rotate it
  • Arrange the axle parallel
  • Give it a decent tug
  • Ask for help from others

Can I Put A CV Axle In A Wrong Position?

No. Doing so is what causes inner CV joint failure.

If it is not arranged properly, problems with the wrong axle can occasionally develop.

The difference in axle length between a manual and automatic transmission axle on some cars may only be a few millimeters. But it could result in a plunge joint that is either too shallow or too deep.

The surfaces of the balls, bearings, and races may be harmed by the CV or plunge joint bottoming out if the axle is too long.

Under certain circumstances, the axle can pop out of the plunge joint if it’s too short.

Why Do I Hear A Clicking Sound From My Axle?

With constant velocity axles, the transmission can drive the wheels while allowing for more bearing flexibility.

If your automobile makes a loud clicking noise as you go straight, your CV joint may be broken.

Ball joints are mounted in a rubber shaft boot, flexible enough to move the chassis and wheel bearings forward.

During driving, a ripped shaft boot spilling grease causes the parts to be dry and lack lubrication, which generates a “click.”

What Causes A Transmission Fluid Leak In CV Axle?

Can a bad cv axle mess up your transmission? Similar to what we mentioned above, this is easy to happen.

In some cars, the axle seal supports it and seals the transmission. The seal can’t keep the axle correctly if it sustains any damage, making it more likely to pop and loosen.

And this leads to transmission fluid leaking.

Conclusion 

When you notice the CV axle not seated properly symptoms, it’s advisable to fix them as soon as possible.

Continuing driving is dangerous as it can damage other parts and especially affect your safety on the road.

You can learn to fix it at home, or for a better diagnosis, asking for help from a technician for fixing or axle replacement is a great choice.
