For information purposes (I know know nothing but specs regarding CV joint grease): what is the NLGI rating (and brand/name) for the CV grease you are referring to?
I find CV grease as being NLGI 1 or 2 (on a quick search). The Deere product is NLG 0 and the Penrite product is made to replace/service NLGI 00 and 000.
NLGI 1 is thicker than NLGI 00
Grade 0 and Grade 00 are considered to be self-levelling grease (which is required for steering boxes). Grade 1 is the consistency of tomato paste, and Grade 2 is the consistence of peanut butter.
