Thats NLGI, not NLG1. It is an NLGI 2, thus the #2.

#2 and #7 are slip yokes, which want moly lithium based NLGI grade 2. NLGI 2 is the majority of greases in the auto parts stores. NLGI grade is shown on back of tube.
For the other joints use non moly general purpose lithium NLGI 2
Yes, grease is better than no grease, but you might as well use the correct one.
Is NLGI#2 ,that's good ??

Yes. NLGI 2. get one tube with molybdenum, one without. Buy 2 grease guns with flexible hoses.

PROPELLER SHAFT JOINT GREASE
Models:
’96–’99 4Runner 4WD
Use a grease gun to apply:
(my edit: Lithium base, NLGI No. 2) multi–purpose grease to the No. 1, 2, 3, 7 and 8 grease fittings. (Slide Yokes, Spiders)
Apply molybdenum disulfide lithium base chassis grease, NLGI No. 2, to the No. 4, 5 and 6 grease fittings (Double Cardan Joint)

Is it NLGI#2? Probably....You'd have to ask whoever designed the label that doesn't clearly early state what NLGI rating it is. You could obtain some clearly labelled NLGI #2 grease and compare the two.
I'm with the others that just buy a lithium-based, #2 Molybdenum Disulphide["moly"] grease and lube everything with that. Moly grease is dark gray to black in color.
Do not mix lithium-based grease(the most common kind for automotive) with another type of base: I've done it in the past and it can cause both greases to become stiff and hard(start the jokes now...3...2...1...)
I bought Valvoline Synpower grease. It has moly added, and the "syn" means it costs more.

The '2' refers to its viscosity. 2 is thicker than 1, which is thicker than 0, which is thicker than 00. "The NLGI has established a scale to indicate grease consistency which ranges from grades 000 (semifluid) to 6 (block grease). The most common NLGI grade is two and is recommended for most applications." Step-by-Step Grease Selection
Moly is best for sliding surfaces, like slip yokes.
Non moly is best for spinning surfaces, like wheel bearings.
It has to do with the way moly works. It is like tiny super hard ball bearings. "It does become part of the metal surfaces by creating a layer of Mo - S lattice on the metal surfaces when they are under high pressure and friction. This layer is an antiscore, antiwear, antifriction, and antioxidant layer." New Tie Rods, Need Grease Recommendation | Grease | Bob Is The Oil Guy.
"Sliding or rubbing contact such as with automotive ball joints, sleeve bearings, some gears, etc., requires both extreme pressure and anti‑wear qualities along with a tenacious film to prevent squeeze-out, washout or both. In this type of application, the use of solid lubricants to aid in the prevention of wear is common, with molybdenum disulfide being the dominant solid." Application is Key in Grease Selection.
"Bearings (ball, roller, needle, etc.) normally see much less contamination but experience wide variations in both speed and temperature. Here, you need a grease that has outstanding mechanical stability (very minor softening or hardening), excellent oxidation stability (long life) and performance over a wide temperature range. Where temperatures do not exceed 250 degrees F, the lithium 12‑hydroxy greases find the widest use. When temperatures increase or long life is required, either a lithium-complex or polyurea can be used."
Thats why non moly is specified for wheel bearings. This is what I gather from all of the stuff I read when figuring out the moly vs non moly question.

I can't seem to find moly grease !!!!!
You posted pictures of two different brands of grease in this thread, that specifically stated they contained Molybdenum Disulfide, right on the packaging..
Speaking of New Jersey, I'm at E-town dragstrip, right now.
So valvoline syn blend should be good then
? For slip yoke and even for every other zerk there. Or the red and tacky Lucas is good for other zerks. The coastal brand is for domestic cars. What u doing at e-town drag strip lol. I live 15 from there.

Yes, the Valvoline would be good. The Coastal brand doesn't know whether it's being used on a Domestic or Foreign car. It would be fine to use.
As for E-town, I've worked on various NHRA Top Fuel Dragster teams for 10+ years.

Holy cow, this has gotten out of hand...
Slapdappy, read my grease reference thread. I have included both the FSM and the TSB's from Toyota themselves on what grease to use in which zerks, they are nto consistent themselves. I read through a bunch of the bobistheoilguy stuff on this, and both opinions were common there. Additional research showed that moly grease is NOT bad for rolling mechanisms such as bearings, and in fact moly was an important part of the development of sealed bearing technology as the moly remained as a lubricant even after the grease itself has been washed out over time. High speed and high temp applications seem to be ideal applications for moly.
Now I am not claiming to be the end all decider on this issue, but I wrote that grease thread after extensive research, and after reading bobistheoilguy and many other sources. I read alot about the thought that building up the moly layer is bad for tight toleranced mechanisms, but if you look outside of bob, you will find there are many other facts than just what is presented there. Together with other sources, I think that the argument of moly being bad for bearings is not correct. The use of moly in sealed bearings seems pretty common, so it can't be that bad... And FYI, in my research I read many posts by people claiming to be toyota techs at toyota dealers some said they use only MP grease, some said they use only moly grease. The only thing that was consistent was that NO toyota tech claimed to use multiple greases, they just had 1 big source of grease.
Kolelt, relax. If you need grease, just buy some grease, don't stress about whether it's moly or not; you can always switch back next time. As was pointed out, you have found moly grease, both the valvoline and the coastal clearly state they are moly greases. Don't worry so much about the grease being claimed to be for japanese or domestic only. Just buy any of those 3 you took pictures of, and use just the 1 grease gun. You don't need 2 guns.
To Pluton's point, you don't want to mix lithium grease with other types of grease, but most available automotive greases are lithium based, so most any MP or EP grease is fine to mix.

I assume moly and non moly greases exist for a reason, that molybdenum has specific properties which make it appropriate for some applications and inappropriate for others. I assume this premise is the basis for the ongoing discussions about which is best for a given application. I am surprised that there is not a simple and definitive answer easily found online.
Right or wrong, I've got it lodged in my mind that moly is for sliding surfaces and non moly is for spinning ones like wheel bearings.
I read your thread many times when I was trying to figure out this thing several months ago. Thanks for taking the time to post it. It must have entailed many hours of searching and reading. I assume I read many of the same threads from many of the same sources and you are correct about some saying moly, some saying non moly, each having reasonable arguments, and there being no real consensus other than greasing with either is smarter than not greasing.
The fact that Toyota has published conflicting specifications about this is the most vexing part of this query.

3 s/b the limit on the slip, you can go further on the others, but I still like to keep it to 3 since I lube 'er up every spring. :banana:

I don't think there is a RIGHT and WRONG answer here. It's probably a bit like getting from point A to point B, you can get there in a jalopy, or you can get there in a Bentley. Both are better than walking. Moly has been around for a long time, so if there really was a serious problem with using it where it isn't specified, then they would probably caution specifically to not use moly grease.
