Many car owners complain about irritating noise after getting an aftermarket axle. The Cardone 66-1325 is one of the high-performance axles that offer noiseless operation. It has a compact shaft that promotes engine transmission and enables swift rotation. The boots are flexible, which lowers the risk of rupturing.

There is a generous amount of bellows on both sides of the joints. Therefore, the grease material stays within the joint area and keeps it smooth. Moly grease improves the temperature resistance of the axle. It also helps the unit to fight off friction. Moreover, the grease keeps dirt from accumulating on the joints.

We must also mention the pair of boot clamps that shield the bellows along with the CV joints. This particular detail adds more to the durability of the axle. Regarding price, the Cardone 66-1325 is not the most affordable option to mull over. That said, you can’t label it overpriced considering the features it comes with.

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.


  • Side Neutral Installation: Side criteria are one of the things you have to think about while buying a CV axle. But, if you are purchasing the Cardone 66-5235, you can ignore that detail since it can fit a vehicle on both the passengers’ and the driver’s side.

The steel shafts of the Traxxas 6851R do a phenomenal job in torque management. It efficiently transfers power from the transmission to the wheels. The external U joints are also instrumental in maintaining such high-performance levels. They are lubricated with high-quality grease to withstand temperature changes and other harmful elements.

The boots are not made of Neoprene, as we have seen in other CV axles we reviewed. But since this axle is for RC vehicles, Neoprene boots are not necessary. These car parts cause far less friction and heat compared to their regular counterparts. So, silicone boots are enough to keep the axle safe.

The nickel coating over the shafts, paired with sleek, ebony silicone boots, imposes a custom look on the axle. The joint pins are firmly secured. So, they won’t fall off when you are operating your RC car in high traction. Its compact and lightweight design makes it perfect for light and medium bashing.

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 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 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
