Can this Schaeffer 238 ultra supreme molly grease be used in the u-joints?

I got a case of 30 for the "THUNK".

A blurb form there site....

Excellent pumpability characteristics for use in centralized lube systems.
Excellent resistance to water washout and water spray-off.
Excellent shear and mechanical stability.
Excellent anti-wear and extreme pressure load carrying properties.
100% reversibility. This property allows Moly Supreme to have the ability to retain its grease-like consistency and remain in the bearings during periods of heat, high shock loading, extreme pressure, and severe mechanical action.
Excellent rust and oxidation inhibiting characteristics.
Excellent resistance to oxidation.
A high dropping point.
Low temperature pumpability characteristics.

Further blended into the high viscosity index 100% paraffin base stocks, PAO synthetic base fluids and the aluminum complex thickener is molybdenum disulfide and a solid lubricant package. The molybdenum disulfide and solid lubricant package allows the Ultra Supreme to act as a "backstop" lubricant when the grease base is either destroyed or wiped away due to unexpected loads, start-up or other conditions which can exceed the capabilities of the grease base's fluid film lubrication. This "backstop" is created by the molybdenum disulfide's and solid lubricant package's natural affinity for metal surfaces. This natural affinity for metal surfaces allows the molybdenum disulfide and solid lubricant package to plate itself to these surfaces in order to form a long lasting solid lubricant film. This solid lubricant film will withstand pressures up to 500,000 pounds per square inch, giving the metal surfaces of the bearings the protection they need during periods of high speed, high shock loads and extreme pressure. The grease's solid lubricant film also helps to reduce friction. This reduction in friction results in reduced wear and a reduction in contact area temperature. This in turn leads to increased equipment, less downtime and extended lubrication cycles.

Ultra Supreme has excellent rust and oxidation inhibiting characteristics, excellent water resistance, shear and mechanical stability, and good pumpability properties. Ultra Supreme also has superior cohesive and adhesive properties. Because of these cohesive and adhesive properties, Ultra Supreme will not wash out, pound out, splatter or squeeze out even under the heaviest loads or vibrations. Due to its superior cohesive and adhesive properties Ultra Supreme is not recommended for use in passenger car automotive wheel bearing applications.

If the tube says NLGI wheel and bearing grease you should be good to go.
 
one grease for everything, spiders, u joints, wheel bearings... i've been using mobil1 on everything for almost 20k miles, about 18 months, without any problem. it immediately eliminated my occasional clunk, so i am sticking with it. although it seems that sticking to the maintenance schedule (every 3k miles?) is required with this grease, the i think the clunk wants to start coming back after about that interval... but that might be true for all of our favorite greases?
 
Howdy! We have used this stuff at work for years. I really like it. I would have no hesitation to use it on just about everything, including filling up the knuckle housings and lubing the ujoints. John
 
My only concern is at the bottom of the first post in red....

They say not recomended for wheel bearings, although it is NLGI #2

Appreciate the replies.:)

I am encouraged by inkpot's knowledge of Schaeffer's super molly:cool:

We have used it for tapered, ball, and needle bearings in high speed, long duration apps with no problem. We also use it in brass bushing type bearings, again, with no problems. I just happen to have a copy of the tech data sheet sitting right here. It says it's good to 350 F degrees, and holds up to 500,000psi. These 3 pages do not mention the disclaimer that you found. They also make a wicked moly gear lube, #209, but that's another story. John

Awesome. This solves the problem of a 30 tube case. Planning on purchasing a Pneumatic grease gun. Thanks Inkpot;)
 
The thickeners in the #238 probably aren't ideal for high speed wheel bearings but the three types of extreme pressure additives are exactly what the drive shaft needs.

This is what I have in the grease gun waiting for the next lube cycle in the 100.

Grab some Amsoil 2000 for the wheel bearings.

I'd buy a tube from you Jason if you're willing to sell me one...I'd like to try it on the slip yoke! Sounds like it might be just the ticket!

Dan I´ll drop one in the mail for you next time I´m on U.S. soil!:)
 
I added this a week ago and have put on about 200 miles. This was added to all drive shaft grease points. The Cruiser has 49,000 miles and now drives like a Lexus. This Cruiser also had a clunk under hard acceleration which is now gone.
 
Thats awesome, feels good to get rid of the clunk!
 
I usually use about 1/2 the tube..... my clunks are all gone:)
 
I ordered some of this from amazon: http://www.amazon.com/gp/product/B002KCWWFC/ref=oh_o01_s02_i00_details

Would this be okay to use in all of drive shaft greasing points? Propeller shaft and whatever the other one is called?

Also, never done this before, is one tube sufficient to do the entire driveline?

This is a good grease and will work ...

... but it's not clear if it has the extreme pressure additives (Moly solid lubricant) that help the most with the "thunk". It claims to have a "synerlec" additive for extreme pressures. You'll have to see if it works.

One tube should last you a few years. You may use a lot the first time if the shafts have been neglected.
