The Ford Barn - View Single Post - Pack the U-Joint?

Ford specifies in the services bulletins for the AA trucks to pre pack the joint with 8 ounces of grease.

Ford specified to use “universal joint” grease which was 600w oil thicken up with sodium tallow soap. Ford also stated that the universal grease was not as thick as wheel bearing grease.

The specification I found for Universal Grease in the November 1932 Ford Service Bulletin has a ASTM Worked Penetration of 310-330 which equates to NGLI 1 “tomato paste” grease. The multi purpose grease used in wheel bearings is thicker, NLGI grade 2 grease.

Here's a chart of grease grades: http://en.wikipedia.org/wiki/NLGI_Grade

A lot of people use the John Deere "Cornhead Grease" for the universal joint which is an NLGI grade is 0.
