What grease for my spicer u-joints 2500 diesel?

Hey everyone this is for my cummins truck, I had a shop change my original ujoints and they put in a greaseable spicer brand they told me.
The reason im asking this simple question about what grease to use is that I sometimes have floods over some backroads where I live in the winter here in norcal near some farm land and they do flood bad and it gets to my ujoints for sure, and so I was wondering if I could just use one brand and be good or change the grease out to something else during the winter? Currently I have lucas extra HD grease the green stuff in my ujoints, is this alright for my application?
I currently grease it every 5k but I have noticed they start squeaking before that and when new grease goes in it stops for about 3-4k, and also do I pump grease until it purges out or would I pump it a few times and be done? Thank you!
 
I have the factory Spicer joints in my truck. I've been using Traveller Marine and Off Road grease from Tractor Supply in mine. It's an NLGI #2 rated grease with supposed salt and water resistance. I usually put a couple pumps in every 3-4K (shaft going to the front differential once a year), or to where you can just barely hear it start to seep out. Not sure if this is the proper way, but it's what I've been doing. Also used this grease on my old S10's suspension components and never had any issue.
 
Why not go to the source.

Lucas red and tacky is a well rounded choice if you have other machines that need greased and only 1 gun.

If not, I'd run that Dana stuff just because.

Would this grease work if it hits water for a bit? I would prefer to use one grease type and be done with it, since I dont know too much about this lucas XD green grease.

Would the green HD lucas grease I have just be the same thing? Only reason im asking is because of the flooding I have here in the winter so I dont want that to affect my grease if it cant handle water well.
 
I've been using Delo Grease EP NLGI 2 in everything for a while with no issues. I'm using it in the universal joints on all of our farm equipment PTOs and personal vehicles as well as any equipment wheel bearings I have with a zerk.

Interesting that you are getting squeaking after a few thousand miles. Wonder if that's a sign of a warranty issue?

I believe spicer only specifies a nlgi #2 lithium so you should have many affordable and well performing options. If you are really worried about water above all else look and the Schaffer or the amsoil grease. I use that grease Lucas for a GP and bike grease and it seems robust, sorry to hear it'a working poorly for you.


FWIW my all purpose automotive grease gun grease is valvoline synpower but I do use jet lube Simone grease nlgi #3 for poly bushings.
 
Use what Dana / Spicer recommends for grease constituents. It's been so long, I haven't looked, but I settled on NLGI #2 lithium complex soap thickener, medium vis oil (nonsynthetic since it gets spit out and needs regreasing), and MO2 fine dispersed additive for boundary friction antiwear. I used to use Mobilgrease EP 2 with Moly, but since they consolidated distributors and it's not locally available I switched to Mystik available at Fleet Farm.

Don't know what your Lucas grease is made of.

You might try and grease you joints really well and remove the zerks and put in plugs. Personally, the zerks I've had were not water proof as I can blow air though easily them with whatever pressure my lungs can produce. I had a rear spicer go out in about 3 years, it was several months after I drove in a small flood. Since I've switched to Redline grease.
 
If they squeak in 5,000 miles after greasing.....Somethings wrong. The "Blue Seal" Spicers don't seal very well, You need top of the line non-serviceable Spicers with the White seals & thrust washers.

My number one choice is Delo EP #2. My favorite for over 20 years. Mystic JT-6 Hi-Temp is a very close second.
 
Give you a recommendation just based on hundreds of Cardan shafts with U joints all over the lumber industry I have had to design and make last.

The basic joint itself is a needle bearing application where the rolling media and surfaces are hardened.

Any good grade EP grease will suffice as far as the basic tribological requirements go but then comes the loads specific to the application.

Technically the grease could last whatever the L-10 for the joint is but that's only measures in a lab at steady state and at 0 alignment deflection ( most joints can tolerate up to 21 degrees thereabouts)

As each one of those changes- the lubricant needs change so what you may need to do is look at the replenishment frequency to keep good "front line" grease in there as your load profile requires ( which may be radically different than the guy next door with the same truck). Of course the purging helps too.

I believe that activity and assessment will benefit you more in performance and reliability over the long game than hunting for a better grease.
 
Spicer recommends Spicer ultra premium synthetic grease, Chevron Ultra Duty EP2, or compatible lithium based NLGI 2 grease. I have used multiple brands of grease lithium with and without moly over the years and the most important thing is to keep them greased and make sure all 4 caps are taking grease.

I'd use a moly-free grease - that Chevron grease works. I've been using WD-40 Specialist Multi-Purpose for U-joints. It meets GC-LB specs and uses calcium sulfonate.
 
Mystik - for me never dries up. In the old days, my dad applies whatever he have on his grease gun.
A word of caution: Do not get into a flooded area where your car get stranded where water will get inside car's u-joint. You need to re-grease your u-joint immidiately using grease fitting. If not your u-joint not last long.
