I guess I'm a bit late to the party on this thread. Back when I was a Pantera guy we had the same discussion. Turns out TRW who bought out the original manufacturer of the Pantera rack changed the recommendation from 90w gear oil to 0w grease because it doesn't leak out or pool in the boots where it has little effect. Ow grease is hard to get in less than 10 gallon drums but assembly lube is about 0-0.5w and that's what most forum people have converted to by now. I converted mine when I replaced my steering rack bushing (yes Panteras have that problem too!) and never had any issues with overdamping.
