Now why don't you just simply use what's made for it, instead of corn head grease, gear oil, STP, Vasiline, etc.
Penrite Steering Box Lubricant is made for that exact purpose. http://www.penriteoil.com.au/products/classic-car-oil/steering_box_lubricant , http://www.penriteoil.com.au/pis_pdfs/PI_Steering%20Box%20Lube.pdf .
Is it more expensive than a tube of John Deere Corn Head Grease? Sure, but it's not supposed to be a consumable if you seal up the gear box you shouldn't have to add any for years.
