G'day folks,
Just a belated followup on this bit;
I wonder whether the semi-fluid should be recommended for the
Peerless boxes and diffs as well?
Dunno offhand; will have to check on the OEM grease specs to answer this one. Watch this space...
I've finally found the time to do a bit of research on the Peerless grease [not real easy to find detailed tech info, on this proprietary product], and it would seem that the OEM stuff still uses a Bentonite clay thickener. And it's about the only 'semi fluid grease' currently on the market, which still does so.
Now, the main reason for using Bentonite [as against one of the organometallic soap compound alternatives] in a grease formulation, is/was to confer water resistance properties on the grease. It also makes the grease 'non-melting', FWIW.
However, unlike Peerless, the rest of the lubricant industry has moved on, and can easily match the Water Resistance properties of the older Bentonite based greases with alternative formulations.
A comprehensive tech rundown on this topic from Penrite is at

So in conclusion, the Lithium based Penrite Semi Fluid Grease, can be considered a very suitable lube for these units.
