Earlier this year while pondering the leaking steering sector on the 51, I grabbed a grease gun loaded with Super Tech Lithium Grease, pumped the steering box almost full and a couple thousand miles later, all's good. No leaks and it steers just fine.
I've ran straight chassis grease in several low speed gear boxes around the farm over the years with zero issues. Me thinks we sometimes over think/complicate things involving our old trucks.
