What you want to do in situations like this, is drill down a bit into what the Ford specifications for a particular lubricant in a particular application are (or were), the numbers or names change. Most of us are familiar with NLGI #2 chassis grease used in drive shaft zerks and kingpins. Often this is the only grade available at retail outlets. But there are other grades of grease available. A "00" grade or "self leveling" grease is just about perfect for manual steering gearboxes.
Only the names are changed, to protect the innocent, something like that. Marketing and brand names just confuse people, or make them spend 10 times what they need to.
