From a mechanical perspective, CV (Constant Velocity) joints play a crucial role in front-wheel drivers. For instance, they keep the drive shaft in the right place to ensure uniform straightness of movement.
Also, they export power from the transmission mechanisms to the wheels. This allows you to turn the car wheels with ease when you apply pressure to the gas pedal.
On the downside, CV joints can cause rapid wear of components and transmissions, especially if they’re not properly lubricated. As a result, the joint may malfunction, thus affecting the car maneuvering.
Luckily, applying the best CV joint grease regularly will keep the CV axle and joint functioning smoothly. Moreover, it will protect the transmission units and parts from premature wear caused by water or other contaminants.
But, which is the most effective CV joint grease, and how do you choose one for your car? Well, we’ve got you covered! In this guide, we’ll show you some of the top products in the lubricant market right now.
So, check them out to find the ideal high-quality grease for your vehicle!

What to Look for Before Buying a CV Joint Grease
With so many lubricants available in the market, finding the best CV joint grease isn’t always a simple task. Nonetheless, certain factors will help you make the perfect option. Some of those factors include;
Type of CV Joint grease
Although there are many types of greases available, not every option is suitable for use in CV joints. However, the following types provide outstanding performance in CV joints;
Multi-purpose grease. A general-purpose grease contains properties of more than a specialized lubricant. More importantly, they’re suitable for use in different places. This makes them quite popular among hobbyists and DIY enthusiasts.
Moly EP grease. Moly Ep grease contains molybdenum disulfide, which is usually referred to as moly. On the contrary, EP is an acronym for Extreme pressure.
This type of grease provides better performance than multi-purpose grease when subjected to high pressure. Yet you can use it for general applications and other places with high pressure and sliding motions like ball joints and U-joints.
Lithium grease. With more than 70% market share, lithium-based lubricant is the most popular type of grease across the globe. At the same, they contain various additives, making them suitable for specific applications.
As you know, additives give the grease extra performance capabilities. As an example, they prevent damage to the metal surface. Even better, some additives help the grease operate at extreme temperatures and pressure.
First, the best grease for CV joint should have excellent ability to withstand high temperatures. In other words, it should not melt when subjected to high heat.
Similarly, the lubricant should remain stable and soft under cold temperatures. Both cases will eliminate the need for regular cleaning and greasing.
As far as temperature tolerance is concerned, lithium-based grease is better than sodium- or calcium-based lubricants
The CV Joint grease’s pressure performance determines how it performs in certain applications. In general, the grease can get too thin or shear when subjected to too much pressure. In most cases, this happens under sudden shock or consistent operating conditions.
Fortunately, CV joint greases are engineered to handle high-pressure applications. This ensures that the lubricants adhere well to the metal surface when subjected to extreme loads. That said, Moly greases are considered to have the highest pressure performance/ tolerance.
Moving on, the ideal grease for CV joints should have exceptional ability to provide water protection on the surface it’s applied on. In essence, this property depends on the oil content of the lubricant.
All in all, water-resistant grease protects metal components from corrosion and rust, extending their durability. Also, this feature will come in handy when your car is exposed to saltwater from time to time.
Viscosity refers to the internal friction rate with a fluid/ lubricant, allowing it to resist flow. Generally speaking, grease has 2 major ingredients, a thickener, and a lubricant.
Thickener gives the fluid a consistency to keep it around the moving component, instead of just flowing or leaking away. On the other hand, the lubricant helps to fight friction.
That aside, different types of CV joint grease have viscosity ratings ranging from 0 to 6. A 0-rated lubricant is almost liquid, while a 6-rated grease is very hard.
Most CV joint lubricants have an NLGI 2 rating, which feels more like peanut butter. NLGI is an acronym for the National Lubricating Grease Institute.
Frequently Asked Questions
1. How much grease should you apply to CV joints?
An average Constant Velocity joint takes about 100 to 200 g of CV grease. However, this may vary from one car model to another.
2. How long do CV joints last?
CV joints are very durable and don’t need any maintenance, provided the CV joint boot isn’t damaged. Generally speaking, CV joints can last for about 70,000 – 130,000 miles. Nonetheless, it’s important to inspect the joints regularly to ensure that they’ve adequate lubricant.
3. Can you mix lithium and moly grease?
Moly and lithium-based greases shouldn’t be mixed since they are incompatible. Specifically, lithium grease is a solid-free lubricant, while moly (molybdenum Disulfide) is a solid additive. Therefore, mixing these products will cause them to lose their lubricating properties.
4. What is so unique about greases for Constant Velocity (CV) joints?
A CV joint grease has many unique properties compared to regular lubricants. For instance, the grease has exceptional water washout resistance, providing superior protection against corrosion and rust.
Also, it’s very shear stable for both low and high temperatures. More importantly, this type of grease is mainly used in automotive applications that are subjected to high loads.
The CV joint grease is a special technical fluid that provides various benefits to your car parts. For instance, it will protect the metal components in your car from corrosion, which can cause cavities in the CV joints.
As a result, you’ll notice an audible knock when turning your car’s steering wheel and the transmission efficiency will be significantly reduced. Moreover, this will hinder the free rotation of elements by increasing the friction coefficient.
Luckily, you can avoid these problems by applying the best CV Joint grease to your car. Best of all, the selection process will now be quite simple, seeing that we’ve listed the top products in the market at the moment.
