Best Grease for U-joints

Best Grease for U-joints

If you are looking for the best grease for U joints, you should know the grease types and their uses.

You’ll see grease is referred to as NLGI number one or number two.

What does this mean?

NLGI stands for the National lubricating grease Institute, and they certify grease.

You’ll commonly see NLGI number one and two greases, but these numbers can range from triple zero up to six. These numbers measure the hardness of the oil.

Lower numbers are softer greases and easier to pump over longer distances. If you have a long hose or in cooler temperatures, a number one grease or more insufficient may be best.

A number two grease is the most common hardness for lubricants and consistency. More manufacturers recommend number two greases due to their ability to stay in place over a wider.

NLGI GC means grease is acceptable for disk brake wheel bearings, and NLGI LB means it is sufficient for chassis lubrication.

If they grease NLGI GC LB, it is acceptable for both disc brake wheel bearing and chassis applications.

NLGI No. 2 High-Temperature grease is preferable for the universal joint that is also known as U-Joint.

If you notice noise when making a turn or extra vibration, you need to check U-joint, and it may be a signal for greasing. When the u-joint becomes dry or grease thirsty, you need to lubricate it; otherwise, it eventually fails.

Benefits of Grease:

Reduce friction:

Friction may occur in any dangerous accident that a primary reason for using the grease reduces friction. If moving metal pieces are left to glide across without lubrication, the components are worn more quickly and mechanically fail.


Grease can protect your metal component from corrosion and rust. It also protects from dust and water and, ultimately, it extends your product longevity.

Reduce noise:

When you notice any noise from your metal components like bearing, chains, or any other vehicle joint, that means your metal part is thirsty for grease. And if you don’t care timely, you might face a big problem.

Smooth operation:

If you use lubricant regularly, it gives you a noise and vibration-free smooth experience.
