And
thee most proper lube for CLUNKY Ford Ranger driveshafts is...
Motorcraft XG-8! It's "baby blue" in color, but... no one will question your man-cred cuz it's out of sight, down under, so to speak... a 3 oz. tube (enough to do the slippy-clunky driveshaft at least 2, and some say 3 times) costs $28.xx+ at Ford Parts Counter... or $6.29 at O'Reilly... I sheet ye not. I'm about to use a modest quantity on my PVH hubs... expecting great things, lol...
Being fully synthetic, XG-8 is also safe for (most) plastics... soze Ima use some on my eh-spensive Herman Miller office chair... soon az ah ken figure out exactly where da squeak be comin' from...
