So while one may think that the advancements in lubrication technology go hand in hand with production vehicles this is not always the case, While conversing with classic car owners older designs sometimes will require a unique lube of the past, simply by design, so while it is such a niche market larger grease manufactures will not always produce these type of greases, they become obsolete, Now this is apparent in the Closed knuckle as well as a older type of U -joint used in Dodge passenger cars,
It is known as the Ball and Trunnion U joint, this older design owners have found very little success with newer lubricants, The Original lube is described as something between gear oil and grease, with tremendous clinging ability, This describes to a "T" what this type of grease is
Now on the average the mechanic using the grease does not know a whole lot about what it is or how it is made, only what he can see, so by simply smelling or feeling the grease mechanics can get some what of a idea of what they are working with,
So in this day in age when mechanics or techs as what they are called now a days with wear latex gloves to as to protect themselves from this horrendous material they have to work with, less and less is observed,
Aside from smell, that is all about a tech or mechanic can know about them,,
So this type of grease in modern times is generally mis diagnosed as axle seal failure in this closed knuckle application, simply because mechanics or especially Techs are not educated about grease, I know that I wasnt, Only began looking into this subject because of mis leading information from Toyota,
I learned a whole lot in very small time, it all had made sense because I had worked with all types of grease over the years but never stopped to learn about it, never wondered, its funny looking back, I had seen semi fluid in wheel hubs but never thought about it,
Just packed it with #2 grease like anything else, now what is the unique aspect of this axle is that the wheel bearings are also lubed by this #0 grease, and since it acts more like a oil longevity of thirty or more years can be obtained, Since the lube is designed to flow thru the spindle bushing, so its simply not a good idea to use two types of grease for the same assembly, as the grease experts state even greases of the same base can have incompatibility issues,
This is one of the main reasons this Short Fiber grease, Soda grease , Sodium grease is no longer used, Incompatible with any other base of grease,
So much easier just to use and have one type of grease , So while little niche older designs that are engineered for this type of grease, not enough demand, simple, becomes obsolete,
