What to look for before buying a grease for slip yoke (Buying Guide)

best grease for drive shaft slip yoke

When you are in the market for the best grease for drive shaft slip yoke, there are some factors you need to consider. Otherwise, you may end up with a lubricant that isn’t ideal for use in driveshaft slip yokes. Some of these features are; 


Water can easily wash away the lubricant and harm the drive safety joints & applications. For that, it’s important to look for grease that has excellent water resistance.

Besides, this will allow it to form a protective shield against moisture. This will protect the metal components from rust and oxidations, thus extending their longevity. 

Pressure performance 

The role of slip yoke is to erode before heavy loads cause the mechanical components to wear and tear. Unfortunately, some lubricants tend to erode faster due to extreme pressure.

You can avoid this by choosing a slip yoke grease that has exceptional ability to withstand severe pressure conditions. In that regard, Moly EP greases are considered to have the highest pressure resistance. 

Temperature resistance 

Temperature resistance is another crucial factor when choosing the best grease for slip yoke. High temperatures can cause the lubricant to melt prematurely. Once that happens, they will drip off the car components they are intended to protect. 

On the contrary, extremely low temperatures can cause the lubricant to solidify. As a result, they become so stiff to the extent of cracking when subjected to high-pressure conditions. 

With that in mind, choose a lubricant that stays stable, both at low- and high- temperatures. Luckily, some slip yoke greases can withstand temperatures as high as -40 deg F and as low as 400 deg F. 

Chemical composition 

The chemical composition of a lubricant is one of its most important features since it determines its properties. Synthetic lubricants contain various materials like petroleum, silicone, mineral oils, metal composites, silicone, surfactants, etc.

Some even contain special additives like molybdenum, which increases the grease’s lubricating properties.

Also, additives provide the formula with other important features like anti-oxidant, anti-wear, and anti-corrosion.


Applying grease on slip yoke every now and then can turn out to be a very daunting task. That’s why it is important to look for a lubricant that will last for a long time. That way, you don’t need to lubricate the slip yoke any time soon after application.

Besides, buying durable grease will help you save money and extend the longevity of car components. 

Final Word 

Lubricating slip yokes should not be avoided since it will extend the durability of your car’s driveshaft and keep it running smoothly.

And now that you’re acquainted with the list of the best slip yoke greases available, there is no reason to keep the driveshaft unlubricated.

Any of these lubricants will guarantee unparalleled performances, even when subjected to heavy pressure and severe temperature conditions.

Just remember to keep the factors we’ve mentioned in mind before you make your final buying decision. 

Frequently Asked Questionss 

1. How often should you lubricate your vehicle’s driveshaft? 

You should grease your car’s drive shaft every couple of mounts to prolong its life. If that’s not possible, lubricate it at least once a month. Doing so will have a huge impact on your car’s performance in the long run. 

2. How do you lubricate a drive shaft? 

Knowing how to grease a drive shaft will help you to prevent wear & damage that may be caused by friction. Here’s how to go about it; 

First, ensure you’ve got the right type of slip yoke grease. More importantly, never use engine oil or lubricating oil to lubricate the drive shaft. Similarly, avoid using moisture-sensitive lubricants. 

Next, pour some grease on the spline and let it drip down the driveshaft. This technique is known as the drip method. 

3. What’s the best type of grease for lubricating slip yokes? 

Lithium-based grease is perhaps the best type of grease for lubricating drive shaft slip yoke. This is because it has excellent resistance against most chemicals, water, extreme temperatures, and high-pressure applications. 

4. How much will it cost to grease slip yoke? 

The cost of greasing your vehicle’s driveshaft will depend on the type of grease used as well as your car’s lubricating needs.

Also, the average cost will depend on whether you need to replace or change any component in the process. All in all, lubricating slip yoke is an affordable service for most people.
