Perhaps it’s an age thing? Perhaps “split sleeve bearing” or other derivations of same have become obsolete?
It’s an interesting thought. Perhaps there are more terms from the days of carbureted engines and ball joints with zerk fittings that will disappear for lack of use when those of us long-in-the-tooth are no longer here?
I have an 826-page hard-bound reference book entitled "The Constitution of the United States of America and Selected Writings of The Founding Fathers. It’s all in “Old English”. The entire book is populated with terms, words, and spelling no longer used. Yet they were commonplace in the 1700s. Perhaps I’ve lived long enough to be actually seeing language evolution in the automotive world. As a matter of fact, I’d bet that we commonly use terms that didn’t exist when I was a young man 1/2 century ago. And I wouldn’t be surprised to find old words and phrases the meaning s of which have changed. “Tune up” comes to mind.
