Benefits of Wheel Bearing Grease
- Stabilize the bearing's structure. The bearings play a vital role in facilitating wheel rotation. For that reason, their structural integrity is vital for safety, and it can be stabilized by grease or lubricants.
- Reduce friction. The grease reduces friction between the bearings and adjacent components (axle and spindle). The heat generated from friction can also lead to wheel bearing failure. Friction can cause the deterioration of the seals, balls, or raceways.
- Easily rotate your wheels. Greasing your bearings helps to reduce friction in your wheels, so they can rotate with ease. The bearings will rotate smoothly even as they bear the weight of the vehicle and endure high pressure and powerful forces at high speeds.
- Keep the bearings in good condition. Grease lubricates and protects the bearings from wear and corrosion. Also, some bearings have a seal that locks in the grease and keeps out water and other contaminants to prolong its life.
- Long-lasting. Grease will last longer than thin lubricating oils when added to moving metal parts. Most greases can also withstand being exposed to the elements for a long time without thinning, freezing, or washing out.
- Keeps out contaminants. Grease acts as a great sealant and keeps out contaminants such as dirt and debris. This helps your wheel bearings to spin smoothly for optimal efficiency.

Best Wheel Bearing Grease Pricing
- Under $30: Some of the best chassis, trailer axle, and wheel bearing greases are found within this price range. The greases mostly come in 14-ounce bottles or 3.5-ounce tubes. You typically have to purchase a pistol grease gun separately with most of the products here.
- Over $30: At this price, the greases simply come in larger cans or in sets of six or more tubes. Also, expect to find some of the best marine wheel bearing greases that sport the highest level of water resistance. Some multipurpose greases come with their own piston guns for easy application.
The best greases can form a protective shield against water and moisture. This helps to protect the metal from rust and corrosion so it can last longer. You must have water-resistant grease if your vehicle is frequently exposed to saltwater.
Viscosity is the rate of internal friction within a fluid that enables it to resist flow. Different types of grease are rated at a viscosity ranging from zero to 6. The ideal rate for a wheel bearing grease is two, which feels a lot like soft peanut butter.
- Temperature Tolerance: The best grease should remain stable even at high temperatures. Lithium-based greases have the highest temperature tolerance in comparison to calcium- or sodium-based greases.
- Pressure Tolerance: Some greases are formulated to withstand high-pressure conditions, such as an emergency brake on the wheels. Most brands indicate the maximum pressure limit for their products. Moly EP greases have the highest pressure tolerance.
- NLGI Number: The National Lubricating Grease Institute (NLGI) consistency number is a grease grading system that can also influence your buying decision. It rates greases by how thick or soft they are. Greases used in wheel bearings usually have an NLGI 2 rating.
- Application: Some greases come in packaging that allows you to apply them directly. Others will require a grease gun or some other form of applicator.

Honorable MentionValvoline Multi-Vehicle Moly-Fortified Gray GreaseCheck Latest Price
This grease is specifically recommended for Ford, Lincoln, and Mercury vehicles—“where M1C75B NLGI GC-LB grease is recommended” as stated. It has properties that lubricate from temperatures of 0 to 375 degrees Fahrenheit. The formula includes “moly” (a type of mineral in lubricants) that enhances lubrication ability.
It is also a general purpose grease, so in addition to wheel bearings, you can use it on suspensions, chassis, ball joints, tie rods, steering linkages, and universal joints. It is easy to install in a grease gun.
On the downside, due to moly in the formula, the grease may more easily stain clothes, driveways, workbenches, and other areas. Also, the package may arrive damaged.

The polyurea base makes it last four times longer than regular grease. It’s also plastic-safe, and packed in a user-friendly grease gun cartridge. Able to withstand high pressures and temperatures of up to 560-degrees Fahrenheit, the product has an NLGI-grade 2 rating. It can be used on farming and construction equipment and heavy-duty trucks.
One downside is the polyurea base isn’t compatible with lithium-based greases, which are often compatible with almost all grease types.
If you are looking to spend the least time possible greasing your wheel bearings and lubricating hard-to-reach areas, consider CRC White Lithium Grease. It comes in an aerosol container and sprays like oil, but it adheres to the surface like grease. Formulated with advanced additives that provide enhanced film strength, corrosion protection, and heat resistance, it’s great for providing long-lasting lubrication to heavy-duty metal applications such as wheel bearings, even under stressful conditions. Aside from that, this grease is water-resistant and works effectively up to a temperature of 300 degrees Fahrenheit.
The main complaint we noted lies with the design of the spray system. It doesn’t provide an even spray so the application can be quite messy. Also, it can stain non-metal components.
This is great wheel bearing grease for high-temperature situations. It is manufactured specifically for both drum and disc wheel bearings. The formula contains anti-wear additives, corrosion inhibitors, and water-resistant components for excellent protection in demanding environments. It helps prolong wheel bearing life and provides a smooth ride. It’s also heavy-duty and tacky (in a good way) compared to other brands.
However, you may want a thicker grease to pack tapered roller bearings that have the inner race pre-installed. Also note that there are no specifications on the can, such as standards ratings or a melting point.
Sta-Lube is a sodium-based bearing grease designed for drum and disk brake wheel bearings and other slow-speed bearings. It’s also a short-fiber grease with some of the best adhesive and water washout resistance capabilities. The product can withstand severe pressure conditions and has a temperature tolerance ranging from zero to 325-degrees Fahrenheit. Sta-Lube’s formulation includes a highly refined base oil and an added polymer to increase its lubricity and cling properties. The product is packaged in a 14-ounce can and has an NLGI grade rating of 2. It’s recommended for autos and trucks with a drum brake system and for janitorial and cleaning supplies.
The downside of the product is that it has a lower temperature tolerance in comparison to standard greases.
- Some wheels come with completely sealed bearings, meaning you can't add more grease to the unit when you notice a rumbling sound. This often indicates that the bearings are straining. In that case, you would have to buy a new set of bearings.
- Grease certification is an easy way of knowing what type of grease is suitable for your bearings. Greases that are only GC-approved are ideal for disk-brake wheel bearings. LB-approved greases are suitable for chassis. GC-LB approved are suitable for all types of wheel bearings and chassis.
- Do not mix different brands or qualities of wheel bearing grease. It may compromise lubricity and other protective properties. Clean out the old grease with white spirit before you apply the new grease.
- For a grease base, choose a product with an aluminum-complex or a lithium-complex grease base since they have some of the best anti-wear and anti-corrosion capabilities. Do not use copper as a grease base as it forms an electrochemical reaction with the bearing metal. The product of that reaction dissolves in salty water and leads to faster deterioration of the bearings.
Q: Do I have to grease new wheel bearings?
It depends on the make of your car. If it has a sealed pre-assembled hub unit, then you don't have to grease them since the new bearings come pre-greased. Sealed bearings are never greased but replaced when they start to wear out. Only grease bearings for vehicles with unsealed locks or hub units.
Q: How will I know that I need to replace my wheel bearings?
Just like any other metal component of your vehicle, the bearings will give some telltale signs that they need to be replaced. You may start to hear a rhythmic thumping noise that sounds like a card that's stuck on the spokes of a rotating wheel. The noise gets louder the more the bearings wear out.
Q: What is the ideal dropping point for wheel bearing grease?
Dropping point refers to the temperature at which the grease changes from its semi-solid state to a liquid state. Most greases have the recommended dropping point of 500-degrees Fahrenheit. Grease with a low dropping point won't serve its purpose as a lubricant.
Q: How long do wheel bearings last?
Depending on the quality of the bearing, they normally last between 85,000 and 100,000 miles. Some premium bearings can be pushed to 150,000 miles. However, you shouldn’t rely on the manufacturer’s advertised lifespan to determine when you should replace your bearings. To be on the safe side, check the condition of the bearings every 30,000 miles.
