You folks living in Florida probably don't have to worry, but be careful filling the box with grease if you live where it gets really cold.
A number off years back, I bought a CK5 Jeep. Everything was OK until the first really cold day (-20F) when I promptly stuffed it into a snow bank on the first corner I came to.
The blasted wheel wouldn't turn. The PO had filled the steering box with grease and it had turned to cement in the cold. I had to clean the box out and replace it with gear oil to get it to operate when the temperature was low.

".......So sanded it all down and resprayed. ......" Been there. done that on a couple of paint jobs over the years. Usually took me a couple of days to get over being mad before I started...
