I have old Craftsman socket wrenches from the early 1970's which haven't seen much use. I think the lubricant in them has dried out because they have a somewhat notchy feel when in use. Is there any way to lubricate them? (They are not the micro ratcheting style)
Only a fool would attempt it, and God help me, I am that fool!
Clean out the gunk with WD-40 then use something like Dupont Multi-Lube.
soak the end of it over night in some thin solvent like WD40, Marvel Mystery Oil, or even diesel fuel.
Mine come apart with a circlip and you can clean the guts. I don't believe mine are lubricated in any way other than surface oil like WD40 or something. Mine are vintage 2000 though.
