A Grease Story

[IH8mush]

Personally I was interested to learn about this, Grease and Oil Specialist, encouraged me to write a article about this, I have, will continue to do so, use this type of grease in other applications,

Why,?

Last longer.

I finished the repair on the 79 F250 and will post the pictures,

Since all I get is Flack from folks about this on the website that I paid to talk about this grease, "the4x4network" I will post them here, I hope Bob wont mind,

Thanks

79 F250 Open knuckle overhaul

The next few photos show the old grease, in wheel hub, I have observed that only the grease that is packed into the bearing is used, the excess grease in between the two bearings is just along for the ride, does not get used to any benefit, that I can think off,

This Rig was packed full a estimated half a 14 0z Tube between the two wheel hubs,
While only 10% of the grease does any lubing,

 

[IH8mush]

Amount of grease in 1 hub

 

[IH8mush]

Combined amount of grease,

You can see the unused grease, identify the color, see that is never been used,

The Black more oily grease has been broke down and heated (Used)

As mention a very small amount,

 

[IH8mush]

Since I will be using a grease that is described as incompatible with any other sort of grease, Cleaning out the pre lubed spindle bearing will be required,

This would be a good idea anyhow, to ensure whatever grease your using will be compatible,

 

[IH8mush]

New spindle seal, while it is just a molded rubber seal it does the Job containing the semi fluid grease,
It is important to replace these seals, as well as the Dust boot on the axle and thrust washer,

these complete kits are available,

 

[IH8mush]

At first I hand packed the bearings but all is required is pump a nice bead of goop around the bearing, and spin it after plenty of rotations the semi-fluid works its way into the bearing, rather easy,

 

[IH8mush]

Same procedure on the outer bearing

 

[IH8mush]

Pre-lubed bearing

 

[IH8mush]

Pumping the wheel hub with lube, If you get the Tube wedged between the spindle and behind the outer race tips it up a smiggin to get a good amount inside the hub, The Ideal level would be a half way full I would think,

 

[IH8mush]

Just as the lube begins to drool out, is when I stop pumping and insert the outer bearing,

 

[IH8mush]

The concern of the lube leaking out thru the hub, is always area that would potentially cause trouble,

Now some hubs bolt on,to the wheel hub, no worries with that style,

This type is the style that bolts to the inner hub gear and not to the wheel hub,

So I measured the inside and out of this set up and was dis-edified to find almost .015 movement between the two parts,
Now this is a double edge deal, while concern of leakage with a fluid lube it also means that water can get in and contaminate,
I have talked to guys who Mudd race and they have to rework the bearings quite often,
So My solution to this was to run a bead of silicon around this area, and clean and prep the wheel hub and silicon that as well, I have found that it is required to apply silicon to both surfaces to ensure a good seal,

I also recommend applying a bit of silicon to the shoulder of the bolt,

[IH8mush]

The silicon of choice is the "Right Stuff" sold at Napa, its a bit spendy but well worth it,

 

[IH8mush]

Completed Repair,

Took the New School Ford got thrown back 10 years long lasting semi fluid grease in wheel hub,

 

[IH8mush]

The Next project is to Re work the 1971 F250,

This Rig has the Proper lube on one side, and a #2 regular wheel bearing grease in the other,

The side with the #2 grease will be full of dirt, the other (original) side will be clean,

So thanks Toyota, Now I know what Ford meant by "Proper lube"

Probably because it has a proprietary asbestos base thickened with dredgings from Hiroshima Bay and micronised lead/mercury amalgam solid lubricant additives.

Toyota does not tend to have good technical customer support. I think it might be because the guys who would know the answers (the lube engineers) are in Japan and don't speak English. I think the Toyota model for a long time was Toyota builds them ships them to US Sales and US Sales sells them with out any mixing of roles. With more US design and Manufacturing that will probably change.



Exactly,
The Salesmen Educate the Techs,Write the books, So this is why there is a incorrect recommendation in the FSM,

Salesman write repair manuals.
Yeah, you bet.
