The GSP NCV12184 is suitable for both driver’s and passenger’s seat installation. The boots come with a Neoprene build like most premium CV axle offerings currently in the market.  

Neoprene, aka polychloroprene, is a synthetic rubber that boasts a solid chemical formation. For this reason, it is highly invulnerable to heavy shock, heat, and stress. Therefore, you can expect this axle to stay operational in temperatures where many CV axles would start malfunctioning. 

GSP made no compromise in quality while designing this product. That’s why they sourced it from high-end raw materials. The final phase of production takes place under the CNC Machine technique. In this stage, the parts are cut per their size requirements, and then they undergo final assembly.  

To make the joints and boots more tolerant of friction, GSP has implemented moly grease on the axle during assembly. Also, the presence of molybdenum disulfide in the grease solution makes it immune to intense temperature changes. As a result, the axle can withstand severe conditions and prolong its service period.

Features


  • Moly Grease Application: Moly grease in the joints and boots of this axle makes them more resistant to abrupt temperature shifts and abrasion. The existence of molybdenum disulfide in grease grants it high-temperature tolerance.

The Cardone 66-5235 can be an excellent fit for a Toyota, Lexus, and other brands.

Some axles have specific side requirements. You can’t install an axle to the right side of your car if it’s meant for the left and vice versa. With the Cardone 66-5235, you won’t have to worry about the side orientation of the axle. You can install it on both sides of your car without any hassle at all.

What makes the installation even smoother is the notches that mimic the ones you would find in your car’s OEM axles. So, in terms of fitting, you wouldn’t be able to differentiate between OEM and aftermarket. You would also get an axle nut with the package, just in case your previous one has become defective.

Cardone has used Neoprene to construct the boots. As we have already mentioned a few times, Neoprene is the go-to boot material for high-quality axles. So, they hold up quite well over time. The boots also have additional bellows to make the unit more impervious to heat, friction, and other hostile factors.

Cardone 66-4060, like most Cardone CV axles, has a large selection of compatible vehicles. The Neoprene boots are insusceptible to frequent ups and downs of temperature. Consequently, the risks of boot failure are virtually non-existent. An ample amount of bellows also back up the boots and prolong their lifespan. 

The bellows hold the 3% Moly grease solution, which is responsible for effortless boot movement. The grease is sourced from molybdenite, a graphite-like natural mineral. It alleviates the friction between the parts and slows down their decay. Moreover, it keeps the joints clean.

The transmission seal goes through heat treatment and machine finish for immaculate fitting. Cardone deployed their proprietary Cardone’s Selected Engineering methods to fix the shortcomings of the previous model. Therefore, you can expect an even higher level of accuracy and performance from Cardone 66-4060.

Cardone’s precision rolling technique perfects the threads and splines of the axle. The preciseness of the threads makes the axle easy to mount. On the other hand, the splines firmly connect the inner axle to the transaxle through a mating hub. In doing so, it supplies torque to the wheels via the transaxle.

Features

How To Choose The Best Aftermarket CV Axles?

How can you be sure that the CV axle you are buying is up for the job? Here are the factors you should keep in your mind while choosing a CV axle:

Wheel Drive Type

To get the best aftermarket CV axle for your car, you need to know the nature of the wheel drive your vehicle has. Cars with front-wheel drives use CV, aka constant velocity joints. Some vehicles need rear CV axles too. So, check your car specifications to determine what type of CV axle you would need to suit your wheel drive type. 

Internal Joint 


Structurally, CV axles come with two joints. There is an internal joint and an external joint. Both joints serve their own purpose. The inner joint brings together the transaxle and the transmission through the mating hub. In doing so, it transports power from the engine to the vehicle. 

External Joint


On the contrary, the external joint incorporates the wheels into the rest of the system. As you can see, the joints are crucial in making a car operate smoothly. So, joint quality has to be up to mark for getting optimal performance from the vehicle. Check the bearings of the outer joint and spline thread finishing to validate the robustness of the joint.

Boots


Boots protect joints from heat, friction, and grime. So, durable boots ensure a durable axle. Neoprene tops our list of boot materials because of its flexibility and resistance to detrimental agents. Also, look for extra bellows, which dampens the stress even further. Below-par boots put your axle at risk. So, make sure the boots are durable.

Grease


Grease has an uncomfortable texture, so we usually like to stay away from it. But when it comes to axles, grease is actually a good thing. It makes boot motion smoother. That means there will be less friction, and the parts will wear out at a slower rate. It also builds higher heat resistance. 3% molybdenum sulfite grease is the best one for this purpose.

Center Shaft Quality


CV axles routinely deal with humungous amounts of power and torque. Most of this stress goes through the center shaft. So, look for a sturdy center shaft that can put up with enormous stress levels. CNC-designed axles are the best in torque handling. We suggest a stainless steel construction for better durability.

Frequently Asked Questions

Q. How Long Does A Good CV Axle Last?

A good quality CV axle should last you approximately five years. However, mileage is a better benchmark to answer this question. Usually, a CV axle can cover 60,000 miles before making way for a new one. This number can be greater or smaller based depending on the quality of terrains you drive on. 

Q. Is It Okay To Drive With A Faulty CV Axle? 

A CV axle will not stop working as soon as it gets bad. But, that doesn’t mean you should drive with a faulty CV axle. You should replace it as soon as you can. Even though a bad CV axle can still last around five months, you would never know when you lose control of the car. Therefore, change the axle as early as possible. 

Q. What Are The Telltale Signs Of An Underperforming CV Axle? 

Look out for the following signs to detect a bad CV axle: 

  1. A popping sound comes out when you turn the vehicle. The sound originates from the loose joints of a damaged CV axle.

  2. A knocking sound while driving. However, this could also indicate non-axle issues. So, take the cat immediately to a servicing station if you hear such noises.

  3. If you see grease on your wheels, it possibly means the boots in your CV axles have leaked. 

  4. Vibrations while driving and tends to increase as you accelerate.

Q. Can I Only Replace The Axle Boots Instead Of Changing The Entire CV Axle?


In some cases, you can. But, you would have to detect the boot damage at an early stage. If the grease doesn’t come out of the boots, and no dust or water enters inside, changing the boots is all you need to do. However, you would have to change the whole axle if the boots stay damaged for a long time.

Q. What Is 3% Moly Grease?


Moly grease is a high-performance grease with a molybdenum disulfide concentration of 3%. It has widespread applications because of its excellent resistance to abrupt temperature shifts. Because of its fundamental properties, moly grease is a common lubricant in the automotive industry. 

Q. Can I Change My CV Axle Without Professional Help?


You can, mostly. Some CV axles are very easy to install. You can easily install them by watching DIY videos on YouTube. But, some CV axle models are a bit difficult to handle. In those cases, you should hire a professional mechanic for the job. 

If you don’t have any prior experience working with auto parts, we recommend asking for professional help.

Q. Do You Need To Change Both CV Axles At Once?


You should only change the axles simultaneously if both axles wear out and become inappropriate for use. However, if one CV axle remains functional while the other one becomes unfit, you should only replace the one that has gotten out of service. There is no need to change both axles if they are not broken at the same time. 

Final Words
