Just edited thread to add some findings on the grease.
This was the green I was referring to. I ordered it.

Lucas Xtra HD is mentioned in the thread but i don't see it being lithium based..
This is what’s in my gun, I squeeze it in the slip yoke as well even though I’m sure there’s a better option. If I get enough of a education/bashing from this comment I’ll buy another grease gun for those drive shaft zerks.
That is one option I was considering. Tractor supply has it nearby. https://www.tractorsupply.com/tsc/product/mystik-jt-6-hi-temp-grease-no-2
I have the AMSOIL multi purpose sitting here that they sent me for free when I ordered some oil sampling kits.
Manual says you can use "no moly" option for spider and slide.
Claude gave me these options when I asked to pick a lithium complex no moly option..
Since you have the AMSOIL already why not run it? This is one of those rabbit holes that has no ending or perfect answer. I’d say the frequency of greasing is more important than finding the absolute perfect grease.
Yeah, that’s what I’m gonna do.
Oreilly has Mystik, Green grease (says Lithium), and old formula Red N Tacky.
Mystik is good and I use it for spider yokes along with amsoil - it’s also good for wheel bearings if you have a trailer, etc. Valvoline pictured is good too. Just make sure it’s compatible and recommended. The one I used in the past from Napa isn’t offered here. Someone who I can’t remember posted on mud about g4700 molykote for our slip yokes. I did a deep dive and that’s some good stuff. Spendy and not readily available though.
I have a dedicated set of grease guns for my greasing needs. Yes - I know I have a problem.

My impression is the u-joint design is good enough that grease quality isn’t critical as long as it’s done often enough. I don’t know if the Lucas green changed formulas but it has served me well for probably 200k miles of service over a couple of Landcruisers.
I also have separate grease guns. It’s just the easiest way if you are using different types of grease.
I run the Mystik in my trailers as well. If I remember my rabbit hole journey I believe it faired the best against water immersion. I try to avoid water crossings as best I can but you never know where that trail may lead and turning around isn’t always an option when you have your base camp in tow.
I don’t have anything against it but was confused at why it was mentioned a lot since it’s not showing as lithium based. And the polyurea base is not compatible with a lot of the other products.
I will try to track down whether it’s always been polyurea.
I got Lucas Xtra HD (which is green so assume what you are talking about) and I have applied at 30 and 40k miles and will repeat at least every 10k miles. I hope it will serve me well and following this conversation I know I displaced a lot of the factory grease in the process (though it seems the drive shaft splines had little from factory in there).
In other words, hope displacing the old with new iby pumping it in (especially the spiders) allows it to work well to grease and lubricate the services.
And to late to reconsider so I am going to stay the Lucas HD course.

On the Lucas X-Tra HD polyurea question: Yes, it has always been polyurea. The original Lucas X-Tra Heavy Duty product page and data sheet from at least as far back as 2008 confirmed it as a polyurea grease, and Lucas's own product data sheet describes it as using an advanced polyurea thickener system. There was some confusion over the years because some forum posts and even a tractor dealer labeled it as lithium-based, but those were errors. Lucas themselves confirmed the green X-Tra HD is polyurea-based and is NOT compatible with any grease that is not also polyurea — and that most competitors' green greases are NOT polyurea, so don't assume compatibility by color. It's always been the same formulation — the confusion was never a formula change, just widespread misidentification.
As long as it's the only product you are using, it's fine but just be careful going back and forth with other products because of incompatibility.

Thanks for clarifying. I bought a bunch of Lucas X HD since they seem to be short on supply 2 years ago so 1) I am going to stay the course so it is all the same grease and 2) re grease a bit more frequently to ensure all factory stuff is out.
I have an email out to Lucas Oil to see what kind of polyurea since there's a compatibility difference between Conventional and Shear stable.
Considering most folks haven't had any issues with it, it might be shear stable (more compatible). I will report back what they say.

EDIT: adding response from Lucas.
This is a polyurea conventional grease (not considered "shear stable") and is NOT compatible w/ other grease types. *Grease Compatibility Chart attached for reference. Let us know if you have any questions and thank you for your support. Have a greatrest of your day!
