In the mid 80s we bought a new straight mast rough terrain forklift on Ford tractor/industrial running gear. The manufacturer had redesigned to whole counterweight design, but Ford hadn't yet built a heavier steer axle. This resulted in frequent and continuous failures of king pin bushings(they would peel out), and snapping spindles. While I was battling the company, I was steered by a local parts house to the Drydene synthetic grease, and it made a big difference in keeping the bushings in longer. Eventually the manufacturer was bought out, and we made a settlement to retro tgecomplete new heavier steer axle.
So,"boutique grease" can make a difference.
