Greasing Leaf Springs
Mike, What effect does grease between the leaves of a pre-50 spring have please? Besides stopping them squeaking. Kind Regards, Mike Mike, If the springs are really pre-1950’s, the grease will help them slide against each other easier and help stop the squeaking.

Monoleaf Mistake
