Call Eljay
Call Eljay oil company and talk with Randy there, he has a degree from the NGLI,
Aside from that look at the engineering of what you have in the frt ends of these things
Look at the original engineering when is was on the drawing board for a weapon of war
Look at the engineering that went into is some 10 years later in Japan where they made improvements to contain a semi fluid lube, we have one Fellow posting up from the real world that knows the advantages of a semi fluid grease as a better form of lube
Read the steering knuckle lube thread on IH8mush,
I will list the items that they are incorrect about the design.
A baffle just behind the little axle seal, a last effort to contain the semi fluid
The knuckle is not vented to the atmosphere, as it warms up in there, slight pressure will build and the semi fluid could possible leak into the third member housing , This pressurized (depending on atmospheric pressure) is a ideal enviroment for the knuckle assembly for the birfield and all other components
The spindle bushing, the lube grove entry points one of them is wisely placed at the six o clock position to ensure lube flow even if the knuckle went down in fluid level that low fluid will flow thru here it is designed to do so
The fill plug location is much higher that the static level on domestic rigs, this is an improvement from the original design for two reasons, one the viscous lube will be flung up to the upper trunion bearing and also the entire wiper seal will be lubed wet forming a viscous seal (a seal of oil)
Another improvement Toyota made is the addition wheel bearings seal, some will call it a dust seal but Toyota lists it as a oil seal
But basically it is a dust seal, to protect the primary oil seal in the wheel hub
By design the seals are for oil, listed as such in the books
I will re-post the link to Utah Rock crawler where I took photos and documented these things, especially the lube thru the spindle I caught so much flak about that is was unreal but I measured It, took a picture of the baffle and most Damming of all call Randy and ask him For some "Moly based grease" it does not exisit!! only in the mushroom factory
The special service Toyota tool lists them as oil seals as well
All of these items are denied to exist or be possible at the mushroom factory
