When it says "Contains a ridiculous amount of moly!" but then doesn't give you the percentage I'm immediately skeptical.

Completely agreed

 

[93Chewbacca]

and what NLGI number should i use? 1, or 2? I ask because i have been pulling parts together and grease is the last thing I'll need beside luck and shop rags and a 24 case of beer....

NLGI 2 is what the FSM specifies

 

[93Chewbacca]

and what temp rating should this grease have?

Temp ratings vary, but something suitable to your climate is usually recommended

I loaded my knuckles with Palladium earlier this year. I need to grease my u-joints now but couldn't find palladium anywhere locally. I searched Amazon and also came to a dead end. It looks like the palladium has been discountinued for Valvoline VV985. Is VV985 recommended for knuckles and u-joints?

I saw that @93Chewbacca also liked the Amsoil. Is there any particular one? Amsoil makes a 5% moly NLGI#2 for off-road applications, Synthetic Polymeric Off-Road Grease.

Synthetic Polymeric Off-Road Grease, NLGI #2

I use this for u-joints and its good stuff

Anyone used any of the Texas Refinery Corp greases?

I was looking at the Moly Paragon 3000. Link below. no affiliation, just bored at work and cruising through old threads.

Looks like a good grease. It uses a calcium sulfonate thickener, which isn't exactly what the LC FSM specifies, but calcium sulfonate greases are compatible with lithium greases, so you should be ok to mix the two. Calcium sulfonate greases typically outperform lithium greases too.

NAPA stores carry Valvoline Palladium.

For the front axle repack on my 1983 FJ60, the two service manuals I have (one the reprint from SOR, the other an actual full Toyota FSM in the flesh) have two different greases used for the whole job. Can anyone explain why that is and what special purpose each offers. Here is a rundown:
A = Molybdenum disulphide lithium base grease
B = Multi-purpose grease


used in
A = All birf rebuilding/packing, knuckle bearings, 3/4 of all of the knuckle ball
B = "lip of the oil seal" in the knuckle, the entirety of the hub pack


To restate, why are two different greases used ?

 

[mct75]

Moly is for things that slide, multipurpose is for things that roll.

Thanks ! Much appreciated.

So, are there any recommendations on which MP grease to use ?

Thanks again.

I'm reading more off other boards and I think I see what the can o' worms is about. Something about "backwoodsgoop" and whether Toyota intended for there to be two different grease types or one. I don't have enough knowledge to know right from wrong so I am going to stick with the FSM for now.

 

[mct75]

Just about the only thing that everyone can agree on is that fresh grease always is better than old grease or no grease. Anything with the "GC-LB" spec is "good enough."

 

[Irish Reiver]

Does it matter if you mix grease? I had a moly based grease in the birfs but recently had no options other than to use mobile 1 grease. It isn't moly fortified . Not sure if i should top off with the mobile 1 or the moly stuff which I now have.

 

[mct75]

Some say that different brands/types/formulations of grease can interact and turn into a thin liquid. I have never seen it happen but it is never recommended to mix greases.

You should inspect the grease in there to make sure it looks ok, or plan on replacing all of it. I would do option number 1 honestly.

Is a "lithium complex" grease the same as a "calcium-lithium complex base grease" ?

OK - after reading through this thread non-stop, I decided to look into the Valvoline Palladium. Meets all the specs and can be purchased by the tube at NAPA.

 

[93Chewbacca]

Some greases can mix, but I wouldnt recommend it.

Recommendations for Mixing Greases

Its perfectly ok to have molybdenum in rolling bearings and such, fyi. When you have sliding parts, especially under heavy load, that is where a high pressure lubricant such as molybdenum (moly) is necessary.

 

[JLH911]

So what MP grease is everyone using for the bearings? I saw someone mention that they use one type of grease for both birfs and bearing, but Isn't Moly grease a big no-no for bearings?
