Yes, the red line mark is the correct lube port, but getting oil in there can be messy too. With the modified hex bolt with Zerk fitting, you then use a grease gun filled with whatever you want - oil or cornhead grease, and a lot less messy. Like I said, a worn out box isn't going get better just by adding lube.
