The FSM calls for NLGI #2 Molybdenum Disulphide Lithium Grease for the slip yokes and NLGI #2 Lithium Grease for the u-joints. Nobody that I am aware of (even dealers) keeps and utilizes two distinct types of grease for these. Dealers employ inexpensive bulk grease (if they even touch your zerks at all). In the end, if you lubricate your u-joints every 5,000 miles as directed by the service schedule, any high-quality grease will work just fine and will last longer than the rest of the truck.
I use Amsoil Series 2000 synthetic grease, which is superior than any moly or lithium grease and meets all industry standards: Synthetic Amsoil Series 2000 grease
However, I note that Amsoil now has a new synthetic grease designed especially for “off-road” (heavy machinery) applications: Off-Road Synthetic Polymeric Grease – NLGI #2 by AMSOIL

What sort of grease are U-joints covered in?
MOLY grease is the best kind of grease to use on U-Joints. This grease has been approved for this use. Another excellent option is the lithium-based EP NLGI 2 Grease. Additionally water-resistant, this grease shields the joints from rust and corrosion.
What sort of grease ought to I apply to my drive shaft?
Before we ship any Tom Wood, the drive shaft is completely lubricated. So all you have to do at first is install it. To ensure a long life, you will eventually need to lubricate your drive shaft. Grease your shaft after each oil change as a good starting point. Grease your shaft as soon as you arrive home if you go wheeling and drive through a lot of mud or water. By doing this, the contaminants will be removed before they can cause too much damage. Any grease will work, although we advise using a high-quality grade 2 grease with calcium sulfonate as an addition. Just be sure not to miss the cv center ball! View the center ball anatomical images down below.
For u-joints, is moly grease beneficial?
Moly grease is an excellent lubricant for U-joints, according to Valvoline, and has been used successfully in U-joints for a long time in the automotive and heavy equipment industries.
U-joints can be over-greased, right?
In my opinion, u-joints are usually over-greased. Heck, sealed bearings are now standard on most automobiles. Depending on usage, I’m fine with yearly or monthly, barring excessive angles or loads.
Are ball joints benefitted by green grease?
Numerous applications for cars and motorcycles employ green grease. U-joints, chassis lube, CV joints, upper and lower A-arms, ball joints, tie rod ends, polyurethane bushings, disc brakes, steering linkages, and wheel bearings are a few examples of where you can see it used efficiently.
Describe No. 2 grease.
Synthetic lithium PTFE lubricant and grease is known as high temperature spindle grease. High Temperature Spindle Grease is resilient at extreme heat and won’t melt or run even in a direct flame because it has no melting point and an infinite shelf life. Appliance motors, dental drills, brake calipers, and all other high-speed rotating equipment, robotic slides, and equipment working in high temperature settings all benefit greatly from the use of high temperature spindle grease.
LOX-8 Lubricant There is also NLGI 2. In industrial applications, NLGI Grade 2 grease serves as a multipurpose lubricant for severe chemicals and oxygen. For plain and antifriction bearings operating under a moderate load and at medium speeds, Grade 2 grease is a great lubricant. In high-speed, high-temperature components like wheel bearings and electric motors, NLGI Grade 2 grease lowers friction and wear. Wherever there is oxygen (approved for both liquid and gaseous oxygen) or harsh chemicals like chlorine or strong oxidizers, LOX-8 Grease is the best choice. LOX-8 Grease works well as a lubricant as well as a sealer. Use when lubricating the pumps, regulators, valves, O-rings, and service bearings for oxygen.
Wherever harsh chemicals like chlorine or potent oxidizers like oxygen are present, LOX-8 Paste is the best choice (approved for liquid and gaseous oxygen). Both a superb lubricant and a terrific sealer, LOX-8 Paste excels in both areas. Chemical processing, industrial gases, and other aggressive applications are only a few high-tech industries that use LOX-8.
Chem-8 is a silicone PTFE lubricant and grease that performs admirably with mechanical tools like hinges when frequent autoclaving is necessary. In high pressure gases, Chem-8 performs well (except fluorine and oxygen). It is chemically inert, watertight, and heat-resistant to 300 F. When working with aluminum against aluminum, vacuum systems, instrument threads, mechanical instruments, and high vapor pressure applications, use Chem-8 as a lubricating grease.
How frequently should a PTO shaft be greased?
Regular greasing of the PTO shaft is necessary to prevent universal joints from failing and shaft seizing. Failure to oil your shaft on a regular basis or in accordance with the maintenance schedule for the PTO shaft could cause end thrust, which could potentially break the implement’s gearbox. Standard universal joints should be greasing every 20 hours or every 8 hours in case of extreme situations. Remember! To reach the four cross bearings, grease takes the shortest route through internal apertures. Individual cross bearings can fail because of overheating and poor grease being baked in one port, which prevents grease from getting to that bearing. To ensure grease flows you all cross bearings, make sure to fully expose the guard cover. It is inadequate to grease through the little guard access hole. Check the condition of the PTO safety guards as well; if they are broken or in bad shape, arrange for replacement to ensure the operator’s safety.
How often should U joints be greased?
Compared to permanently sealed u-joints, greaseable u-joints have been in use for longer. Older u-joints may always use some lubrication. So, in response to the question, “Should I lubricate older u-joints? Yes, it is the answer. Every 5,000 miles, it’s recommended to lubricate greaseable u-joints. The u-joint brand determines the precise service interval.
When lubricating your u-joints, you must:
- Lift your SUV or truck
- Use a grease gun and grease cartridge to add new grease to the u-joint.
The top bearing cap or the cross of greaseable u-joints has a grease zerk. That zerk serves as an entrance for the fresh grease.
Every 5,000 miles, be careful to lubricate your u-joints (or as recommended by the manufacturer). They’ll probably live longer than u-joints that are permanently sealed.
NLGI 2: What Does It Mean?
An NLGI grade of 1 grease has the consistency of tomato paste, whereas an NLGI grade of 3 grease has the consistency of butter. A lubricant that is NLGI grade 2, which has the stiffness of peanut butter, would be utilized in the most frequently used greases, such as those used in vehicle bearings. In comparison to NLGI grades 000-0, grades in this range can operate in a wider temperature range and at faster speeds. NLGI grades 1, 2, or 3 are frequently used as greases for bearings.
How do you use a grease gun to lubricate a U joint?
Greasing Procedures
- Remove any dirt or additional grease from the region surrounding the U-joint and the zerk fitting.
- Grease the Zerk Fitting with the grease gun end.
- Grease the U-Joint and start pumping.
- Keep an eye out for any liquid or debris being expelled from the joint’s caps.
- When fresh grease starts to be expelled from the joint, stop.
Describe the slip yolk.
The slip yoke, a crucial component of the drive shaft of your car, is what permits the shaft to bend when driving over unlevel, bumpy terrain. Your drive shaft’s U-joint can continue rotating correctly under more demanding circumstances because to this flexion. The slip yoke moves power from your transfer case to your front axle using this technique.
When should Moly grease not be used?
Molybdenum disulfide can have a corrosive impact on the metal surfaces and is unsuitable for bearings and other components that move quickly, thus greases containing it shouldn’t be used in situations that see a lot of water penetration.
Can lithium grease be applied to U-joints?
The most frequent reason for early failure in u-joint kits and slip assemblies is improper lubrication. The operational needs of a fleet will typically be met or exceeded by properly sized U-joints that are sufficiently lubricated at suggested intervals. Premature u-joint kit failures brought on by insufficient lube cycles and improper lubrication of the slip splines and u-joints may also result in other issues, such as slip spline seizures. By flushing abrasive impurities from the u-joints and slip components during prescribed intervals of relubrication, the life of the driveshaft is extended.
What kind of lubricant should I apply to my universal joints that have grease fittings?
- It is advised to use an EP (Extreme Pressure) grease with a lithium complex soap base that has an NGLI grade of 1 to 2.
Are lithium and moly grease compatible?
Compatible with all types of calcium, lithium, and lithium complex greases Offers lubrication and maintains consistency when subjected to shear.
Do U joints need to be rigid?
Precision bearings called U-joints. They should therefore be able to freely move in both axes. Even when completely oiled, a fresh u-joint will typically feel very stiff when moved by hand. After inserting the first two caps into the yoke of the new u-joint, tap the joint back lightly from each side. After placing the clips and pressing the caps in place, do this. To make sure the caps are firmly affixed to the clips, tap the joint from either side. The u-joints may become a little bit more flexible as a result.
It’s horrible if you have to relocate a new u-joint by hand because it got stuck. Any “catching in the movement” is also undesirable. If you discover either issue, pull the joint apart and inspect the bearing to make sure nothing has moved. It should be acceptable to experience some stiffness as long as your new u-joints provide a fluid motion without sticking.
Describe moly grease.
Moly grease is a unique composition that is typically used on pinion gears and splines when metal slides against metal under intense strain. This silvery black solid compound is a metal dichalcogenide and is found naturally as the mineral molybdenite.
Can red grease be applied to ball joints?
It’s challenging to choose Lucas Oil’s Red ‘n’ Tacky as the Best Value option rather than Best Overall. This grease has several benefits and is a great all-purpose lubricant to keep on hand in the garage for lubricating many components of your car or truck, including the ball joints. Again, variety is nothing without performance, but Lucas Oil is an expert in this area. This product has anti-seize reinforcements and good heat, water, and corrosion resistance. The affordable prices are a plus.
Most automotive businesses will have Red ‘n’ Tacky on hand because it is useful in so many different ways. Even though it’s entirely appropriate in most situations, some people are put off from using it and related products for ball joints since they lack molybdenum. Despite claims of a lengthy shelf life, it does have a tendency to split when left out for months.
