High moly grease on spider joints?

For lubricating the drive shaft, this thread:

https://www.toyota-4runner.org/5th-gen-t4rs/285126-beginner-fluid-maintenance.html

recommends Mobilgrease XHP 322 Mine for lubricating the slip yoke, and Lucas Oil Red 'N' Tacky #2 (which I gather is sometimes sold without the "#2" on the product label) for the spider joints.

My understanding is that Mobilgrease XHP 322 Mine is preferred in the slip yoke because it has higher molybdenum disulfide than the Red 'N' Tacky.

Is there any disadvantage to using the XHP 322 in the spider joints as well? The Mobil product data sheet says it is good for "general purpose chassis lube":

as long as it has moly in it, and you are maintaining your drivetrain at least once or twice a year, it doesnt matter.

I use mobile 1, valvoline, and red N tacky....basically whatever is in my grease gun at the time and whatever is the cheapest i can get on amazon.
 
Spicer/Dana who is a very large manufacturer of ujoints recommends their own grease which uses a calcium sulfonate base and no moly.
MolyD should be less than 5% to prevent ujoints from binding up as per ExxonMobil Commercial Vehicle Lubricants Applications Engineer Paul Cigala

Does Spicer grease leak lighter oils out of the grease gun like so many other grease products?
 
Moly is needed for sliders, NaGl2 is called for spider joints by Toyota's manual. I use this Harbor Freight Moly goop for sliders for years without any issues:

This is spot on and I have 340K miles on a 2014 SR5 to prove it. I shoot the spider joints on the driveshaft every 5K miles.

I found an article saying a moly grease can be used in "any component" in an on-highway, heavy-duty vehicle, but the article quotes Paul Cigala as saying that U-joint manufacturers specify a molybdenum disulfide content of "5% or less" to avoid binding in the needle bearings inside the U-joint:

The fundamentals of truck and trailer grease application | Commercial Carrier Journal

The moly is especially good in sliding applications like the slip yoke because it bonds to the surface of the metal, creating an extra layer for sliding over. Mobilgrease XHP 322 Mine has 5% moly content, so it would probably be OK in the U-joints. But maybe the best way is to just have two grease guns for the two different types of components, and lubricate often.

Thanks for all your comments.

One can overthink this, but basically 2 greases would probably be best.
There is a reason why Harbor Freight sells moly grease for $8, Spicer grease is min of $20 and a grease like Krytox is $500, in all cases for a 14oz tube.
General rule Better >$. You would be amazed at sone of the higher end tube prices.

MolyD is a mineral and has particle sizes. Google it.
I used MolyD oil for machining and drilling stainless, can't beat it.
For all suspension parts, I use Moly, joints it's Spicer.
I hate changing joints almost as much as paying someone else to do it.
